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

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

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 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Enhancing urban ecological resilience(UER)is a new concept for modern tourism-oriented cities to cope with environmental crises.Revealing the impact of the urbanization on UER is critical to the sustainability of urban ecosystems.Taking Zhangjiajie,a typical tourism-oriented city,as an example,urbanization level(UL)and UER evaluation system were constructed,and the change trend was analyzed.The Granger Causality Test model was used to discuss the relationship between UL and UER.The results showed that:(1)the urbanization rate of Zhangjiajie significantly increased by 0.531 from 2011 to 2020.Cili county has the highest UL,and Wulingyuan district including a large number of scenic spots has the fastest development trend.(2)The ecological restoration was more sensitive in the face of rising pressure,and showed a synchronized change trend with pressure.The high pressure in 2016 had the most significant impact on resistance.This effect continued into 2019,with an average decline in resistance of 0.802.(3)The UL has significantly promoted the improvement of urban ecological restoration.Specially,tourism urbanization was the most significant in scenic spots,while economic and social urbanization played a major role in other regions for the improvement of ecological restoration.

文摘The Loess Plateau(LP),one of the most ecologically fragile regions in China,is affected by severe soil erosion and environmental degradation.Despite large-scale ecological restoration efforts made by Chinese government in recent years,the region continues to face significant ecological challenges due to the combined impact of climate change and human activities.In this context,we developed a kernal Remote Sensing Ecological Index(kRSEI)using Moderate Resolution Imaging Spectroradiometer(MODIS)products on the Google Earth Engine(GEE)platform to analyze the spatiotemporal patterns and trends in ecological environmental quality(EEQ)across the LP from 2000 to 2022 and project future trajectories.Then,we applied partial correlation analysis and multivariate regression residual analysis to further quantify the relative contributions of climate change and human activities to EEQ.During the study period,the kRSEI values exhibited significant spatial heterogeneity,with a stepwise degradation pattern in the southeast to northwest across the LP.The maximum(0.51)and minimum(0.46)values of the kRSEI were observed in 2007 and 2021,respectively.Trend analyses revealed a decline in EEQ across the LP.Hurst exponent analysis predicted a trend of weak anti-persistent development in most of the plateau areas in the future.A positive correlation was identified between kRSEI and precipitation,particularly in the central and western regions;although,improvements were limited by a precipitation threshold of 837.66 mm/a.A moderate increase in temperature was shown to potentially benefit the ecological environment within a certain range;however,temperature of-1.00°C-7.95°C often had a negative impact on the ecosystem.Climate change and human activities jointly influenced 65.78%of LP area on EEQ,primarily having a negative impact.In terms of contribution,human activities played a dominant role in driving changes in EEQ across the plateau.These findings provide crucial insights for accurately assessing the ecological state of the LP and suggest the design of future restoration strategies.
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.

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With the first rays of dawn peeking through the rainforest at Shiti Village,Dehong Dai and Jingpo Autonomous Prefecture,Yunnan Province,Xu Xiaolong,a bird-watching guide from the Jingpo ethnic group,led a German bird-watching group into the jungle.His great-grandfather made a living by hunting“weird-looking birds”in the mountains.Today,the birds(Great Hornbill)are attracting tourist dollars from other parts of the world without dodging bullets.In Shiti Village,bird-watchers can enjoy the chirping of Great Hornbills and feel the rumbling in the air as the birds fly past.The village on the Chinese border with Myanmar was formerly poverty-stricken,with an average annual income of barely 2,000 yuan(US$305)per household 10 years ago.Today,the average annual income has grown to 150,000 yuan(US$23,075).It is a shining example of the successful practice of the notion that“lucid waters and lush mountains are invaluable assets.”
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The traditional Feng Shui pattern embodies rich ecological wisdom and philosophical thoughts,which are of great significance to the modern sustainable space design.The core concepts of Feng Shui patterns from traditional civilization can provide a theoretical foundation and research framework for this study.By integrating these principles,such as“hiding the wind and gathering the Qi”and“backing the mountain and facing the water”,a functional relationship between urban structures can be established.This approach can help optimize the spatial layout of urban elements,minimize energy consumption,and enhance environmental comfort.It also examines the influence of the ShanShui City pattern in traditional Feng Shui on guiding the development of modern urban ecological networks,as well as its role in protecting and restoring biodiversity through ecological corridors and ecological nodes.The modern urban design of traditional Feng Shui culture focuses on the inheritance and innovation of riotous things and the combination of traditional Feng Shui concepts and modern design concepts to form ecological spaces with cultural connotation.This paper hopes to give some inspiration or methods for contemporary urban design and to reconcile the relationship between human and nature through these thoughts.

文摘Regular quantitative assessments of regional ecological environment quality(EEQ)and driving force analyses are highly important for environmental protection and sustainable development.Northern China is a typical climate-sensitive and ecologically vulnerable area,however,the changes in EEQ in this region and their underlying causes remain unclear.Traditional evaluations of EEQ rely primarily on the remote sensing ecological index(RSEI),which lacks assessments of indicators such as greenness(NDVI),humidity(WET),heat(LST),and dryness(NDBSI).To address these issues,this study employs the principal component analysis method and the Google Earth Engine to construct an RSEI suitable for long-term and large-scale applications and analyzes the spatio-temporal variations in the RSEI,NDVI,WET,NDBSI,and LST.Additionally,geographical detectors are utilized to analyze the driving factors affecting EEQ.The results indicate the following.(1)The RSEI shows a fluctuating upward trend,with an average value of 0.4566,indicating a gradual improvement in EEQ.The EEQ exhibited significant spatial heterogeneity,with a pattern of lower values in the west and higher values in the east.(2)The NDVI and WET exhibit fluctuating increasing trends,indicating improvements in both indices.The NDBSI shows a fluctuating decreasing trend,whereas the LST presents a fluctuating increasing trend,suggesting an improvement in the NDBSI and a slight deterioration in the LST.NDVI and WET demonstrate a spatial pattern characterized by low values in the west and high values in the east.NDBSI and LST demonstrate a spatial pattern characterized by low values in the east and high values in the west.(3)Land use types and precipitation are the primary driving factors influencing the spatial differentiation of the EEQ.The explanatory power of these driving factors significantly increases under their interactions,particularly the interaction between land use types and other driving factors.This study fills the gap in existing EEQ evaluations that analyze only the RSEI without considering the NDVI,WET,NDBSI,and LST.The findings provide new insights for EEQ assessments and serve as a scientific reference for environmental protection and sustainable development.

文摘Global ecological monitoring faces unprecedented challenges from accelerating climate change,biodiversity loss,urban expansion,and unsustainable resource use.Although existing scientific programs and monitoring platforms have improved data accessibility and methodological standards,they remain constrained by three critical bottlenecks:near-real-time performance,intelligent analysis,and comprehensive coverage.Overcoming these shortcomings is essential to advance global change science,climate governance,and sustainable development.This review synthesized recent progress in international ecological monitoring,including major scientific initiatives,thematic and integrated monitoring platforms,and emerging remote sensing cloud systems.These systems have collectively promoted open data sharing,standardized observation protocols,and cross-domain integration.However,critical challenges remain in achieving near-real-time observation,interpretable intelligent modeling,and globally balanced coverage,which limit the transition toward an intelligent and fully consistent monitoring framework.Building on this foundation,we introduce the Global Intelligent Ecological Horizon Project(GIEHP),an exploratory framework aimed at constructing the world’s first Digital Earth Atlas with long-term consistency and high-dimensional integration.GIEHP represents a pathway toward integrating multi-source observations,intelligent modeling,and cloud-cluster computation to achieve near-real-time,multi-scale,and globally consistent monitoring.Its pilot applications illustrate the potential for unified mapping of key ecological indicators and provide a methodological reference for advancing intelligent,data-driven environmental governance.This review not only summarized the progress and limitations of existing monitoring systems but also outlines a forward-looking framework for the next generation of global ecological monitoring.Achieving a truly intelligent,near-real-time,and globally consistent system requires sustained international collaboration,interdisciplinary integration,and open data sharing.We call on the global scientific community to advance this vision and provide robust knowledge support for ecological restoration,climate adaptation,and sustainable development.

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Land use change is a fundamental factor affecting ecosystem’s structures and functions.However,few studies have explored the ecological disturbance caused by land use change from a combined structural and functional perspective.In this study,the ecological structural disturbance index(SDI)and functional disturbance index(FDI)were introduced to quantitatively evaluate ecological disturbance caused by land use change in a typical karst area—Huangping County,Guizhou Province,China during 2009–2019.Results show that although the area of ecological land increased during past 10 yr,there had been a fragmentation trend of ecological land.Agricultural occupation was more severe than construction encroachment on ecological land.The grids with negative structural disturbance were consistent with areas of obvious dynamic loss and gain of ecological land.Ecological fragmentation had a greater impact than habitat gain in grids with negative structural disturbance.The ecosystem service functions of supply,adjustment,support,and culture were obviously affected by land use change,and the total FDI reflects the trade-off among them.Negative FDI values were easily observed in the rocky desertification area or water and soil loss area.The combination analysis of the SDI and FDI indicated the characteristic of codirectional ecologically structural and functional disturbance in the majority of grids.The findings improve our understanding of multiple relationships among ecological disturbances and provide valuable information for guiding land use activities.

文摘Territorial spatial ecological restoration is a crucial prerequisite for optimizing the territorial spatial patterns,enhancing the ecosystem functions,and achieving sustainable development at the regional scale.The Qaidam Basin,located in the alpine arid region of the Qinghai–Xizang Plateau,China,is experiencing desertification,biodiversity loss,soil erosion,and environmental pollution.Selecting the Qaidam Basin as the study area,we identified 9 ecological sources in the region using the Morphological Spatial Pattern Analysis(MSPA)method and the landscape connectivity assessment,and extracted 10 significant corridors and 26 general corridors using the Minimum Cumulative Resistance(MCR)and Gravity models.Then,we determined 114 ecological"pinch points"and 42 ecological barrier points by employing the Circuit Theory,thereby constructing the ecological security pattern of the area.Further,we evaluated the ecosystem health of the Qaidam Basin during 2003–2023 using the Vitality–Organization–Resilience–Service(VORS)model.Finally,we integrated ecosystem health assessment and ecological security pattern to comprehensively identify the key areas for ecological restoration in the Qaidam Basin.The results revealed that the ecosystem in the basin fluctuated toward a healthier state from 2003 to 2023.The average ecosystem health index(EHI)for the basin decreased from 0.34 in 2003 to 0.28 in 2013,followed by a substantial recovery to 0.36 in 2023.Higher EHI values were found in the northeastern,southeastern,and southwestern fringes and lower values were located in the basin interior and northwestern region.During 2003–2023,the areas that exhibited a decrease in EHI were primarily located in the interior and northwestern regions of the basin,while those that exhibited an increase in EHI were located in the northeastern,southeastern,and southwestern fringes,demonstrating expanded spatial differences.This may be attributed to the fact that once an eco-environment is damaged,the ecological recovery of the vulnerable areas within the eco-environment will be slow and difficult.This study identified four types of ecological restoration areas,including corridor connectivity,artificial restoration,ecological recovery,and ecological enhancement zones,covering a total area of 6034.7 km2,and proposed targeted ecological restoration strategies according to these different categories.Our findings can serve as a valuable reference for optimizing the territorial spatial patterns,enhancing the ecosystem functions,and promoting sustainable development in the Qaidam Basin.
