This study examined its population structure and environmental factors influencing its distribution in the semi-arid Karamoja sub-region, Uganda. We surveyed 388 plots (5 m radius) at different altitudes, recording life stages, stem diameters, and regeneration patterns, and analyzed soil samples. Multivariate analyses, including Canonical Correspondence Analysis (CCA), Detrended Correspondence Analysis (DCA), Non-metric Multidimensional Scaling (NMDS), and Multiple Regression Modeling (MRM), identified key environmental factors affecting its distribution. Findings show that O. lanceolata populations in Moroto, Nakapiripirit, and Amudat districts are severely degraded due to overexploitation. The species is primarily regenerating through coppicing rather than seedlings, with an exploitation intensity of 56.6%. Population densities are low, distribution is irregular, and sustainable harvesting is not viable. Soil properties, particularly Ca2+, N, P, K+, Na+, and organic matter, significantly influence its abundance. Conservation efforts should focus on identifying suitable provenances for genetic preservation and plantation establishment. Areas with at least 9 trees per hectare in Moroto, Nakapiripirit, and Amudat could serve as potential sites for ex-situ plantations. Further research should explore how biotic interactions, genetic diversity, and morphology affect oil yield and quality to support restoration, breeding, and domestication initiatives.展开更多

A biological inventory was carried out within the mine’s decade-old progressive ecological rehabilitation sites. This inventory covered insects, amphibians, reptiles, birds and small mammals. The main objective of the inventory was to assess the level of animal recolonization in the 100-hectares’ restored areas. A total of 22 insect genera, 4 amphibian species, 11 reptile species, 43 bird species and 11 small mammal species were found. All of them were strongly settled in the core area within the afforested sites. Prior to the start of the Twangiza mine activities and 4 years before the ecological rehabilitation in the area, the avifauna was depauperate, both in number of species and their abundance. By then, no mammals or reptiles were recorded within the footprint area. The environmental and social baseline assessment identified 38 bird species in 2008, mainly grassland and mobile species, which were using scrub along valley streams as a refuge, outside the current mine footprint. Our results clearly demonstrate the positive impact of the afforestation on insect, amphibian, reptile, bird and small mammal’s diversity in this area.展开更多

Additionally, 5 619.5 m of artificial shoreline has been developed as part of the ecological restoration efforts. Various methods, including UAV remote sensing, orthophoto acquisition, and analysis using ArcGIS software, were employed to assess the length, width, coverage, and other relevant indicators of the newly established ecologically restored shoreline. The findings indicate that the average width, coverage, and ecosystem stability of mangrove forests in the restored area satisfy the criteria for the acceptance of ecological shoreline restoration. Furthermore, a relatively stable ecosystem has been established for over two years. This study offers a scientific foundation for the ecological restoration of mangrove forests and holds considerable significance for the conservation and utilization of mangrove forest resources.展开更多

The present study selected two Forsythia species, Forsythia mandshurica(Fm)-which naturally occurs in a cold temperate zone and Forsythia suspensa(Fs)-which thrives in a warm temperate zone-to reveal their differential chilling defense mechanisms by integrating morpho-physiological,transcriptomic, and metabolomic data. Transcriptome results show that Fm has evolved in a series of adaptive mechanisms designed to help the plants to cope with chilling stress by enhancing sugar, amino acid, hormone, polyamine, and phenol content to improve cell osmotic potential and to mitigate petal browning. Metabolomic data suggested the increased chilling resistance of Fm relies on in the plant being rich in a-linolenic acid, linoleic acid, as well as two amino acids, Phe and Trp, and has low levels of cinnamic acid and gramine in flowers compared to Fs. A higher abundance of glutathione disulfide and NADPH regulated by glutathione peroxidases and NADPH improved the ability of the cellular antioxidant and reduction-oxidation system stability in Fm;Additionally, the elevated levels of pyruvate, a-ketoglutaric acid, and oxaloacetic acid in Fm contributed to a significantly enhanced ATP production in mitochondria. Through Ka/Ks and gene expression analysis,four transcription factors, EVM0025036(bHLH), EVM0010639 and EVM0007275(AP2), and EVM0025908(bZIP) were identified that may contribute to the high cold tolerance of Fm. These adaptations highlight the intricate interplay between genetic and physiological processes that shape the survival strategies of plants in response to their specific ecological niches.展开更多

文摘Land use/cover change(LUCC)constitutes the spatial and temporal patterns of ecological security,and the construction of ecological networks is an effective way to ensure ecological security.Exploring the spatial and temporal change characteristics of ecological network and analyzing the integrated relationship between LUCC and ecological security are crucial for ensuring regional ecological security.Gansu is one of the provinces with fragile ecological environment in China,and rapid changes in land use patterns in recent decades have threatened ecological security.Therefore,taking Gansu Province as the study area,this study simulated its land use pattern in 2050 using patch-generating land use simulation(PLUS)model based on the LUCC trend from 2000 to 2020 and integrated the LUCC into morphological spatial pattern analysis(MSPA)to identify ecological sources and extract the ecological corridors to construct ecological network using circuit theory.The results revealed that,according to the prediction results in 2050,the areas of cultivated land,forest land,grassland,water body,construction land,and unused land would be 63,447.52,39,510.80,148,115.18,4605.21,8368.89,and 161,752.40 km^(2),respectively.The number of ecological sources in Gansu Province would increase to 80,with a total area of 99,927.18 km^(2).The number of ecological corridors would increase to 191,with an estimated total length of 6120.66 km.Both ecological sources and ecological corridors showed a sparse distribution in the northwest and dense distribution in the southeast of the province at the spatial scale.The number of ecological pinch points would reach 312 and the total area would expect to increase to 842.84 km^(2),with the most pronounced increase in the Longdong region.Compared with 2020,the number and area of ecological barriers in 2050 would decrease significantly by 63 and 370.71 km^(2),respectively.In general,based on the prediction results,the connectivity of ecological network of Gansu Province would increase in 2050.To achieve the predicted ecological network in 2050,emphasis should be placed on the protection of cultivated land and ecological land,the establishment of ecological sources in desert areas,the reinforcement of the protection for existing ecological sources,and the construction of ecological corridors to enhance the stability of ecological network.This study provides valuable theoretical support and references for the future construction of ecological networks and regional land resource management decision-making.

文摘Ecological conservation is at a crossroad as environmental stresses around the world intensify and traditional models of conservation exhibit intrinsic weaknesses in their response to present and future problems.In the project,we evaluated novel approaches integrating adaptive management,technological innovations,and community-based action towards more efficient sustainable conservation results and ecosystem resilience.The multi-site experimental design was based on comparison between conventional reserve management and novel integrative models implemented in diverse ecological zones.Data were collected over a period of three years employing remote sensing technologies,in situ biodiversity assessments,and large socioeconomic surveys.These instruments enabled a robust and multi-dimensional measurement of variables such as species diversity,ecological resilience,community engagement,and stakeholder engagement.The results indicate that adaptive strategies significantly enhance real-time decision-making abilities and enhance long-term ecosystem resilience.Further,technology-driven monitoring greatly enhances data accuracy,responsiveness,and early warning capabilities.Besides that,community-based conservation initiatives were found to be pivotal in facilitating local stewardship,enhancing participatory governance,and enabling more adaptive and adaptive policy systems.This research rejects mainstream conservation paradigms by placing importance on flexibility,interdisciplinarity,and inclusivity of governance systems in effectively mitigating the impacts of climate change and loss of biodiversity.Our findings offer strong evidence that emerging paradigms of conservation can provide greater ecological and social sustainability than traditional methods.These results support the need for a paradigm shift towards conservation strategies that are dynamic,collaborative,and technologically integrated,with significant implications for policy formulation as well as operational environmental management.

文摘Studying the coupling coordination development of new energy vehicles(NEVs)and the ecological environment in China is helpful in promoting the development of NEVs in the country and is of great significance in promoting high-quality development of new energy in China.This paper constructs an evaluation index system for the development of NEVs and the ecological environment.It uses game theory combining weighting model,particle swarm optimized projection tracking evaluation model,coupling coordination degree model,and machine learning algorithms to calculate and analyze the level of coupling coordination development of NEVs and the ecological environment in China from 2010 to 2021,and identifies the driving factors.The research results show that:(i)From 2010 to 2021,the development index of NEVs in China has steadily increased from 0.085 to 0.634,while the ecological environment level index significantly rose from 0.170 to 0.884,reflecting the continuous development of China in both NEVs and the ecological environment.(ii)From 2010 to 2012,the two systems—new energy vehicle(NEV)development and the ecological environment—were in a period of imbalance and decline.From 2013 to 2016,they underwent a transition period,and from 2017 to 2021,they entered a period of coordinated development showing a trend of benign and continuous improvement.By 2021,they reached a good level of coordination.(iii)Indicators such as the number of patents granted for NEVs,water consumption per unit of GDP,and energy consumption per unit of GDP are the main driving factors affecting the coupling coordination development of NEVs and the ecological environment in China.
文摘The efforts Xiamen has made in ecological protection over the last 20 years have helped it become a beautiful and clean city.TWENTY years ago,I had the opportunity to travel to the city of Xiamen in southeastern China’s Fujian Province.Unfortunately,due to the fact that I was in a rush,I did not have the chance to see the whole city.My memory of Xiamen was its pleasant climate and unforgettable beauty-I knew if I ever got the opportunity,I would revisit this place.Twenty years went by until I was able to return to this city again.After emerging from the airport,I realized that I had grown older,while Xiamen was becoming increasingly youthful and vibrant.What exactly had given this city such vitality?
文摘Osyris lanceolata is heavily and illegally exploited in East Africa for its essential oils, yet little is known about its population status and ecological requirements. This study examined its population structure and environmental factors influencing its distribution in the semi-arid Karamoja sub-region, Uganda. We surveyed 388 plots (5 m radius) at different altitudes, recording life stages, stem diameters, and regeneration patterns, and analyzed soil samples. Multivariate analyses, including Canonical Correspondence Analysis (CCA), Detrended Correspondence Analysis (DCA), Non-metric Multidimensional Scaling (NMDS), and Multiple Regression Modeling (MRM), identified key environmental factors affecting its distribution. Findings show that O. lanceolata populations in Moroto, Nakapiripirit, and Amudat districts are severely degraded due to overexploitation. The species is primarily regenerating through coppicing rather than seedlings, with an exploitation intensity of 56.6%. Population densities are low, distribution is irregular, and sustainable harvesting is not viable. Soil properties, particularly Ca2+, N, P, K+, Na+, and organic matter, significantly influence its abundance. Conservation efforts should focus on identifying suitable provenances for genetic preservation and plantation establishment. Areas with at least 9 trees per hectare in Moroto, Nakapiripirit, and Amudat could serve as potential sites for ex-situ plantations. Further research should explore how biotic interactions, genetic diversity, and morphology affect oil yield and quality to support restoration, breeding, and domestication initiatives.

文摘Scientifically constructing an ecological security pattern(ESP)is an important spatial analysis approach to improve ecological functions in arid areas and achieve sustainable development.However,previous research methods ignored the complex trade-offs between ecosystem services in the process of constructing ESP.Taking the mainstream of the Tarim River Basin(MTRB),China as the study area,this study set seven risk scenarios by applying Ordered Weighted Averaging(OWA)model to trade-off the importance of the four ecosystem services adopted by this study(water conservation,carbon storage,habitat quality,and biodiversity conservation),thereby identifying priority protection areas for ecosystem services.And then,this study identified ecological sources by integrating ecosystem service importance with eco-environmental sensitivity.Using circuit theory,the ecological corridors and nodes were extracted to construct the ESP.The results revealed significant spatial heterogeneity in the four ecosystem services across the study area,primarily driven by hydrological gradients and human activity intensity.The ESP of the MTRB included 34 ecological sources with a total area of 1471.38 km^(2),66 ecological corridors with a length of about 1597.45 km,11 ecological pinch points,and 13 ecological barrier points distributed on the ecological corridors.The spatial differentiation of the ESP was obvious,with the upper and middle reaches of the MTRB having a large number of ecological sources and exhibiting higher clustering of ecological corridors compared with the lower reaches.The upper and middle reaches require ecological protection to sustain the existing ecosystem,while the lower reaches need to carry out ecological restoration measures including desertification control.Overall,this study makes up for the shortcomings of constructing ESP simply by spatial superposition of ecosystem service functions and can effectively improve the robustness and stability of ESP construction.

文摘Ecological security patterns are paramount to the advancement of an ecological civilization in China,aiming to enhance the stability and service functions of ecosystems to achieve sustainable regional development.However,current regional ecological protection efforts have not been effectively integrated into the regional development planning of ecological security pattern.This study systematically assessed the effectiveness of ecological protection projects in Yanchi County,Ningxia Hui Autonomous Region,China,through the evaluation of landscape ecological quality.Based on the evaluation results of landscape ecological quality,this study used morphological pattern analysis(MSPA),minimum cumulative resistance(MCR)model,and gravity model together to construct the ecological security pattern of Yanchi County.The findings revealed that from 1990 to 2020,with the implementation of ecological protection projects started from 2000,the landscape stability of Yanchi County first decreased and then increased,and the intensity of landscape disturbance first intensified but then decreased,indicating an improvement in the landscape ecological quality and a significant enhancement of the ecological environment in Yanchi County.The ecological security pattern of Yanchi County consisted of 10 ecological sources,10 ecological source points,23 ecological corridors,and 27 ecological nodes.The ecological security pattern of Yanchi County exhibited distinct spatial variations,with stronger ecological security observed in the southern part than in northern part of the county.The ecological sources were denser in the southern part than in the northern part of the county,and accordingly,the length of ecological corridors was shorter and denser in the southern than that in the northern part of the county.Based on the spatial distribution of landscape ecological quality and the characteristics of ecological security pattern of Yanchi County in 2020,we suggested Yanchi County to build four zones to optimize the ecological security pattern construction:the Haba Lake ecological conservation zone,the urban ecological planning zone,the ecological environment restoration zone,and the ecological security improvement zone.This study can provide essential guidance for the construction of ecological security pattern in farming-pastoral areas both in China and worldwide.
文摘The Twangiza mine is located in the Mitumba mountain range, in the western part of the Albertine Rift Valley, just 20 km East of Itombwe Nature Reserve. A biological inventory was carried out within the mine’s decade-old progressive ecological rehabilitation sites. This inventory covered insects, amphibians, reptiles, birds and small mammals. The main objective of the inventory was to assess the level of animal recolonization in the 100-hectares’ restored areas. A total of 22 insect genera, 4 amphibian species, 11 reptile species, 43 bird species and 11 small mammal species were found. All of them were strongly settled in the core area within the afforested sites. Prior to the start of the Twangiza mine activities and 4 years before the ecological rehabilitation in the area, the avifauna was depauperate, both in number of species and their abundance. By then, no mammals or reptiles were recorded within the footprint area. The environmental and social baseline assessment identified 38 bird species in 2008, mainly grassland and mobile species, which were using scrub along valley streams as a refuge, outside the current mine footprint. Our results clearly demonstrate the positive impact of the afforestation on insect, amphibian, reptile, bird and small mammal’s diversity in this area.

文摘This study focuses on urgent research on restoring and enhancing carbon storage capacity in the Beibu Gulf Urban Agglomer-ation of China,a key area in the‘Belt and Road’Initiative,which aligns with carbon peaking and neutrality goals.This research ana-lyzes the spatial characteristics of carbon metabolism from 2000 to 2020 and uses models to identify stable carbon sink areas,positive carbon flow corridors,and carbon sequestration nodes.The goal is to construct a carbon metabolism spatial security pattern(CMSSP)and propose territorial ecological restoration strategies under different development demand scenarios.The results show the following:1)in 2020,the study area’s carbon sink decreased by 8.29×10^(4) t C/yr compared with that in 2010 and by 10.83×10^(4) t C/yr compared with that in 2000.High-carbon sinks were found mainly in mountainous areas,whereas low-carbon sinks are concentrated in urban con-struction land,rural residential areas,and land margins.2)From 2000 to 2020,the spatial security pattern of carbon metabolism tended to be‘high in the middle of the east and west and low in the gulf.’In 2000,2010,and 2020,16 stable carbon sinks were identified.The carbon energy flow density in Guangxi was greater than that in Guangdong and Hainan,with positive carbon flow corridors located primarily in Guangxi and Guangdong.The number of carbon sequestration nodes remained stable at approximately 15,mainly in Guangxi and Hainan.3)Scenario simulations revealed that under the Nature-based mild restoration scenario,the carbon sink rate will reach 611.85×10^(4) t C/yr by 2030 and increase to 612.45×10^(4) t C/yr by 2060,with stable carbon sinks increasing to 18.In the restora-tion scenario based on Anti-globalization,the carbon sink will decrease from 610.24×10^(4) t C/yr in 2030 to 605.19×10^(4) t C/yr in 2060,with the disappearance of some positive carbon flow corridors and stable carbon sinks.Under the Human-based sustainable restoration scenario,the carbon sink area will decrease from 607.00×10^(4) t C/yr in 2030 to 596.39×10^(4) t C/yr in 2060,with carbon sink areas frag-menting and positive carbon flow corridors becoming less dense.4)On the basis of the current and predicted CMSSPs,this study ex-plores spatial ecological restoration strategies for high-carbon storage areas in bay urban agglomerations at four levels:the land control region,urban agglomeration structure system,carbon sink structure and bay structure control region.

文摘Increasing human disturbance and climate change have threatened ecological connectivity and structural stability,especially in semi-arid mountain areas with sparse vegetation and weak hydrological regulation.Large-scale ecological restoration,such as adding ecological sources or corridors,is difficult in such environments and often faces poor operability and high implementation costs in practice.Taking the southern slope of the Qilian Mountains in China as the study area and 2020 as the baseline,this study integrated weighted complex network theory into the"ecological source–resistance surface–corridor"framework to construct a heterogeneous ecological network(EN).Circuit theory was integrated with weighted betweenness to identify critical barrier points for locally differentiated restoration,followed by assessment of the network optimization effects.The results revealed that 494 ecological sources and 1308 ecological corridors were identified in the study area.Fifty-one barrier points with restoration potential were identified along key ecological corridors and locally restored.After optimization,the network gained 11 additional ecological corridors,and the total ecological corridor length increased by approximately 1143 km.Under simulated attacks,the decline rates of maximum connected subgraph(MCS)and network efficiency(Ne)slowed compared with pre-restoration conditions,indicating improved robustness.These findings demonstrate that targeted local restoration can enhance network connectivity and stability while minimizing disturbance to the overall landscape pattern,providing a practical pathway for ecological restoration and sustainable management in semi-arid mountain areas.

文摘The middle reaches of the Yellow River represent a critically ecologically sensitive and fragile area within the Yellow River Basin(YRB),holding significant scientific value for ecological security assessment and environmental management strategies.This study comprehensively evaluates the evolution of the eco-environment in the“Two Mountains,Seven Rivers,and One Basin”(TSO)area of Shanxi Province from 2000 to 2020 based on fraction vegetation cover(FVC)derived from the Normalized Difference Vegetation Index(NDVI),net primary productivity(NPP)calculated via the Carnegie–Ames–Stanford approach(CASA),and the remote sensing ecological index(RSEI).The results indicate a significant improvement in the TSO’s eco-environment from 2000 to 2020,with the RSEI values increased from 0.34 in 2000 to 0.41 in 2020(an increase of 17.76%).Both FVC and NPP demonstrated notable upward trends,with FVC increasing by 22.74%and NPP by 53.11%.Spatially,FVC rose by 21.84%,19.72%and 26.06%,respectively in the Two Mountains,Seven Rivers,and the YRB in Shanxi Province.Similarly,the NPPs increased by 51.60%,48.60%,and 61.65%in these regions over the past 21 years.Both FVC and NPP exhibited decreasing patterns from southeast to northwest,with significant eco-environmental improvements in the northern region and slower recovery in the southern region.Precipitation was the primary causes influencing vegetation recovery,showing positive trends in the central and northern TSO regions,while this trend reversed in the southern.The RSEI value indicate substantial eco-environment improvements in the central and northern areas(Sanggan,Daqing and Hutuo River Basins),whereas the southern regions(e.g.,Zhang,Qin,Fen and Sushui River Basins)remain in poor grade.Human activities,particularly land use/cover changes marked by increased forestation and urbanization alongside decreased cultivated land,significantly affected vegetation cover patterns.This study provides scientific references for formulating policies on ecological construction and high-quality development in the YRB.

文摘The coastal zone ecological restoration project has successfully restored a cumulative shoreline length of 76 km in Fanhe Harbor and Kaozhou Bay ecological restoration shoreline (mangrove forest) located in Huidong County, Huizhou City. Additionally, 5 619.5 m of artificial shoreline has been developed as part of the ecological restoration efforts. Various methods, including UAV remote sensing, orthophoto acquisition, and analysis using ArcGIS software, were employed to assess the length, width, coverage, and other relevant indicators of the newly established ecologically restored shoreline. The findings indicate that the average width, coverage, and ecosystem stability of mangrove forests in the restored area satisfy the criteria for the acceptance of ecological shoreline restoration. Furthermore, a relatively stable ecosystem has been established for over two years. This study offers a scientific foundation for the ecological restoration of mangrove forests and holds considerable significance for the conservation and utilization of mangrove forest resources.

文摘Ecological governance satisfaction is one of the important indicators to measure the ecological revitalization.The paper studies the satisfaction of rural households with ecological governance and its influencing factors in depth through questionnaire survey and other research methods.The empirical analysis conclusions are as follows:(1)at the level of personal influence factors,the satisfaction of rural households with ecological governance is significantly affected by the education level,age and family health status of rural households.However,factors such as gender,occupation,residence time and the number of family members have no significant effect on the behavior of rural households'ecological governance satisfaction.(2)At the level of economic development factors,the total annual family income,the total annual consumption and other dimensions have a significantly positive impact on the satisfaction of rural households with ecological governance.This shows that economic development is a key factor for environmental protection,and the behavior characteristics of the family could seriously affect the effectiveness of rural households'ecological governance satisfaction.(3)At the level of living environment factors,the situation of rural environmental pollution governance,infrastructure and medical conditions have a significant and positive impact on the behavior of rural households'ecological governance satisfaction.This shows that the living environment is also one of the important factors affecting the satisfaction of rural households with ecological governance.(4)At the level of ecological system factors,the three factors of government environmental protection investment,government management measures and government propaganda policies have a significantly positive impact on the behavior of rural households'ecological governance satisfaction.(5)At the level of ecological environment factors,the degree of awareness of ecological environment protection and the situation of environmental treatment have a significant correlation with the behavior of rural households'ecological governance satisfaction.(6)At the level of ecological culture factors,environmental protection education,ecological culture propaganda and rural civilization construction all have a significant and positive impact on the satisfaction of rural households with ecological governance.And relevant policy measures are put forward to improve the effectiveness of ecological governance.

文摘There is a significant disconnect between current aesthetic education and ecological civilization education.Music education focuses on technical training while neglecting the integration of ecological ethics,while ecological education remains limited to knowledge transmission without effective emotional resonance.This has led to weak ecological responsibility awareness among students(a deficiency of 34%)and a disconnection between curriculum practice and ecological themes(87%of textbooks do not include ecological themes).This study employs the theory of dialectical contradiction as the analytical framework,focusing on the core contradiction between“aesthetic isolation”and“cognitive instrumentality.”It constructs a dynamic intervention model of“soundscape domain-ecological consciousness”to reveal the synergistic mechanism of ecological cognitive reconstruction through neural activation(an increase of 21%in alpha wave modulation)and emotional resonance triggered by sound wave vibrations.Based on the principles of quantum acoustics and the interdisciplinary requirements of the Compulsory Education Art Curriculum Standards(2022),this study proposes a practical approach for“ecological soundscape courses.”This includes the analysis of bioacoustic spectra(such as bird song rhythms),the creation of crisis-themed compositions(mapping carbon footprint data to pitch),and a carbon-neutral music performance mechanism.These methods achieve a cognitive leap from“technical training to ecological responsibility.”

文摘Based on the concept of“Lucid waters and lush mountains are invaluable assets”,Chinese government is relying on the ecological and environmental characteristics of cities,in combination with modern ecological,economic,and sociological theories,to achieve sustainable urban development.However,the value realization of ecological products(EP)faces challenges in four major aspects:quantification,trading,transformation,and sustainability.At this stage,seeking breakthroughs to form a stable development path for the realization of the value of EPs is crucial.This paper examines the Guilin Sustainable Development Innovation Demonstration Zone and conducts a case study on oil tea,a characteristic EP.Based on the value realization of EPs,this paper analyzes the oil tea industry in terms of three functions:ecological protection,regional economic development,and traditional cultural support.Drawing on the theory of the gross ecosystem product,this paper examines the role of the value realization of oil tea in improving the quality of the urban living environment and ecosystem functions in Guilin.The results can help promote research on the shaping effects of endemic EPs on sustainable development with respect to the urban economy.Taking a human-centered perspective,the principles of landsenses ecology and traditional ecological knowledge can help analyze the social,historical,and cultural value of oil tea.Combined with on-site research data,a relationship map centered on oil tea culture is created to explore the importance of developing traditional cultural attributes of local EPs in promoting cultural customs,protecting the cultural diversity of ethnic minorities,and driving the development of the cultural tourism industry.By constructing a sustainable urban development model centered on developing local characteristic EPs with the core elements of ecology-economy-traditional culture,this paper aims to strengthen the ecological protection function of cities,promote high-quality economic development,and enhance the soft power of traditional culture.It provides scientific support for the sustainable development planning in Guilin.

文摘Long-term niche differentiation will lead to the evolution of diverse adaptive strategies for species in diverse environments. The present study selected two Forsythia species, Forsythia mandshurica(Fm)-which naturally occurs in a cold temperate zone and Forsythia suspensa(Fs)-which thrives in a warm temperate zone-to reveal their differential chilling defense mechanisms by integrating morpho-physiological,transcriptomic, and metabolomic data. Transcriptome results show that Fm has evolved in a series of adaptive mechanisms designed to help the plants to cope with chilling stress by enhancing sugar, amino acid, hormone, polyamine, and phenol content to improve cell osmotic potential and to mitigate petal browning. Metabolomic data suggested the increased chilling resistance of Fm relies on in the plant being rich in a-linolenic acid, linoleic acid, as well as two amino acids, Phe and Trp, and has low levels of cinnamic acid and gramine in flowers compared to Fs. A higher abundance of glutathione disulfide and NADPH regulated by glutathione peroxidases and NADPH improved the ability of the cellular antioxidant and reduction-oxidation system stability in Fm;Additionally, the elevated levels of pyruvate, a-ketoglutaric acid, and oxaloacetic acid in Fm contributed to a significantly enhanced ATP production in mitochondria. Through Ka/Ks and gene expression analysis,four transcription factors, EVM0025036(bHLH), EVM0010639 and EVM0007275(AP2), and EVM0025908(bZIP) were identified that may contribute to the high cold tolerance of Fm. These adaptations highlight the intricate interplay between genetic and physiological processes that shape the survival strategies of plants in response to their specific ecological niches.
文摘This study comprehensively examines the multifaceted impact of climate change on Morocco’s ecological sustainability and economic development,focusing on four critical environmental stressors:water stress,deforestation,greenhouse gas emissions,and rising temperatures.These interrelated factors contribute significantly to the degradation of natural ecosystems,the decline in biodiversity,reductions in carbon sequestration,and the disruption of ecological balance.Water scarcity—exacerbated by declining precipitation,excessive groundwater extraction,and rising evapotranspiration—threatens the functionality of wetlands,agricultural productivity,and the livelihoods of rural populations.Deforestation accelerates soil erosion,alters hydrological cycles,and leads to the loss of critical habitats,while greenhouse gas emissions and temperature rise intensify climate variability and increase the frequency of extreme events such as droughts and heatwaves.Using longitudinal data from the World Bank(1990-2022)and advanced econometric modeling through EViews 12 software,this study reveals that water stress and rising temperatures have a statistically significant and negative impact on GDP,indicating that climate pressures undermine Morocco’s economic performance,particularly in climate-sensitive sectors.Conversely,the findings show that deforestation and greenhouse gas emissions are positively correlated with short-term economic growth,reflecting a development pattern heavily reliant on natural resource exploitation and carbon-intensive activities,which may offer temporary gains but pose serious long-term risks to sustainability.These results underscore the urgent need for a paradigm shift toward ecosystem-based adaptation and mitigation strategies,including afforestation,wetland restoration,integrated land and water resource management,and the incorporation of climate resilience into national development frameworks.
