The troubles are severe in regions suffering from improper land management and unsustainable practices. The Bio-CircularGreen(BCG) economic model, designed to reduce and recycle resources by using environmentally friendly procedures, has been developed. The Azolla plant represents an interesting model for BCG and for enhancing community networks in Southeast Asia(SEA) because it provides multipurpose materials. Azolla can be used for various applications in agriculture such as biofertilizer and animal feed. However, our understanding and utilization of Azolla are limited. Moreover, collaboration among farmers is insufficient to maximize the benefits of Azolla. In this study, we provide a comprehensive review of the role of Azolla in agriculture. We review the main properties of Azolla as biofertilizers, especially regarding rice production and the interaction with cyanobacteria. For livestock, we discuss procedures to use Azolla in animal feed and evaluate the ingredients of the meal. In addition, we discuss product qualities from livestock treated with Azolla in the diet. This review also describes Azolla-based farming, which is designed for efficient land use and promotes nutrient cycling.Hence, we show that the Azolla plant is one of the key factors for farm-based agroecosystem services which can drive sustainable bioresource management in SEA. Moreover, we also propose the potential development of Azolla to improve its properties as a biofertilizer, a functional feed for animals and humans, and a feedstock for bio-oil production.展开更多

文摘The Qinghai-Xizang Plateau(QXP)serves as a crucial ecological barrier in China and Asia,exerting profound influences on global climate and biodiversity conservation.Gannan Tibetan Autonomous Prefecture(hereinafter referred as Gannan Prefecture),located on the northeastern edge of the QXP,represents a fragile alpine ecosystem in which land use change significantly impacts ecosystem services(ESs).This study established a comprehensive framework,utilizing the Patch-generating Land-Use Simulation(PLUS)model coupled with the Integrated Valuation of Ecosystem Services and Tradeoffs(InVEST)model to predict land use patterns under the natural development scenario,cultivated land protection scenario,and ecological protection scenario for Gannan Prefecture by 2030 and evaluated four critical ESs:habitat quality(HQ),water yield(WY),soil retention(SR),and carbon storage(CS).The primary aim is to elucidate the impacts of dynamic land use change on ESs.The results revealed that,from 2000 to 2020,HQ exhibited minimal variation,whereas CS experienced a slight decline.Conversely,WY and SR showed significant improvements.Under the natural development scenario,construction land was projected to increase by 4247.74 hm^(2),primarily at the expense of forest land.The cultivated land protection scenario anticipated an increase in farmland by 2634.36 hm^(2),which was crucial for maintaining food security.The ecological protection scenario predicted a notable expansion of forest land,accompanied by a restrained development rate of construction land.The ecological protection scenario also showed an increase in the ecosystem service index(ESI),encompassing 26.07%of the region.Forest land and grassland emerged as the primary contributors to ESs,while construction land substantially impacted WY.Water bodies exhibited minimal contribution to ESs.This study enhanced the understanding of land use change impacts on ESs in fragile and high-altitude ecosystems,offering essential theoretical frameworks and practical direction for forthcoming ecological policy and regional planning endeavors.

文摘The Jabodetabek Metropolitan Area(JMA),Indonesia’s largest urban agglomeration,faces severe challenges due to rapid population growth and environmental degradation.Expanding urban areas has led to a reduction in green spaces,damaging ecosystem services,and exacerbating urban heat island effect,soil erosion,and flood risk.Therefore,this study identified key ecosystem service indicators,including Urban Heat Mitigation(UHM),Sediment Retention(SR),and Flood Risk Mitigation(FRM),and defined the spatial pattern of ecosystem services and its management zones in the JMA in 2024.Spatial data and ecosystem service indicators were analyzed using the Integrated Valuation of Ecosystem Services and Trade-offs(InVEST)and spatial clustering analysis tool(e.g.,Rustiadi’s Quantitative Zoning Method(RQZM)Ⅱ),and the results served as the basis for formulating strategic recommendations.This study highlighted significant regional disparities.Jakarta,Tangerang Regency,Bekasi Regency,Depok City,Tangerang City,South Tangerang City,and Bekasi City experienced the increase of urban heat effect and flood risk due to dense infrastructure and limited green spaces.Conversely,southern peri-urban areas of Bogor Regency demonstrated higher ecological capacities,particularly in water infiltration and temperature regulation,but remained vulnerable to soil erosion due to urban expansion.The results underscored the critical imbalance between growing urban demands and the diminishing capacity of peri-urban areas to supply ecosystem services,which is driven by the transformation of green spaces into built-up areas.To address these challenges,this study proposed the Nature-Based Solutions(NBS)by emphasizing forested area conservation in the southern region of the JMA,natural landscape restoration and rehabilitation in the central region,and a hybrid of natural and artificial ecosystem creation in the northern region.

文摘Coastal tourism holds substantial development potential.However,coastal ecosystems are affected by tourism development,which limits the supply of ecosystem services(ES).This study aims to conduct a systematic literature review on the impacts of tourism on coastal and marine ES using the Preferred Reporting Items for Systematic Reviews and Meta-alpha Methods.We initially identified 640 studies by searching titles,abstracts,and keywords.After screening,only 50 studies met the criteria for inclusion in the review.The results showed a significant increase in publications between 2011 and 2023.Most studies were conducted in Europe,Asia,and North and Central America.The most used ES classifications were MEA and CICES.Most studies concentrated on the ES supply dimension(43 studies;86%).Cultural ES(47 studies;94%)were researched more than provisioning(28 studies;56%)and regulating&maintenance(29 studies;58%)sections.Regarding cultural ES,most studies were focused on“Physical and experiential interactions with the natural environment”(34 studies;68%)and on provisioning ES on“Wild animals(terrestrial and aquatic)for nutrition,materials or energy”(18 studies;36%).Quantitative and mixed methods were the most used in the reviewed studies.Most studies identified pressures from“Tourism,urbanisation,and population increase”(27 studies;54%)and focused on“Integrative/common management strategies”(20 studies;40%).Only a few of the studies’results have been validated by external data(10 studies;20%).This study provides an overview of the most assessed marine and coastal ES,where studies are needed with more comprehensive geographic coverage.

文摘Ecosystem services(ES)mapping and models have advanced in recent years.Improvements were made,and the assessments have transitioned from qualitative to quantitative.Although this is an important advancement,the ES mapping and modelling validation step has been overlooked,and this raises an important question in the credibility of the outcomes.This has been an important and unsolved issue in the ES research community that needs to be tackled.This highlight paper discusses the importance of validating single ES mapping and models.Conducting this using field or proximal/remote sensing raw data and not data from other models or stakeholder evaluation is important.A validation step should be mandatory in ES frameworks since it can assess the models’veracity,contribute to identifying the model’s weaknesses/strengths and ultimately represent a scientific advance in the field.This is easier to apply to the biophysical mapping and models of regulating and provisioning ES than to cultural ES,as the latter rely more on perception and cultural contexts.Also,ES supply models are easier to validate than demand and flow models.Robust and well-grounded models are essential for ensuring the reliability of individual ES maps and models and should be integrated into decision-making processes.Although several challenges arise related to the costs of data collection,in several cases prohibitive,and the time and the expertise needed to conduct this sampling and analysis,this is likely an imperative step that needs to be considered in the future.This will be beneficial in establishing ES research and improving decision-making and wellbeing.

文摘Cultural ecosystem services(CES),which encompass recreational and aesthetic values,contribute to human wellbeing and yet are often underrepresented in forest management planning due to challenges in quantifying these services.This study introduces the Recreational and Aesthetic Values of Forested Landscapes(RAFL)index,a novel framework combining six measurable recreational and aesthetic components:Stewardship,Naturalness,Complexity,Visual Scale,Historicity,and Ephemera.The RAFL index was integrated into a Linear Programming(LP)Resource Capability Model(RCM)to assess trade-offs between CES and other ecosystem services,including timber production,wildfire resistance,and biodiversity.The approach was applied in a case study in Northern Portugal,comparing two forest management scenarios:Business as Usual(BAU),dominated by eucalyptus plantations,and an Alternative Scenario(ALT),focused on the conversion to native species:cork oak,chestnut,and pedunculate oak.Results revealed that the ALT scenario consistently achieved higher RAFL values,reflecting its potential to enhance CES,while also supporting higher biodiversity and wildfire resilience compared to the BAU scenario.Results highlighted further that management may maintain steady timber production and wildfire regulatory services while addressing concerns with CES.This study provides a replicable methodology for quantifying CES and integrating them into forest management frameworks,offering actionable insights for decision-makers.The findings highlight the effectiveness of the approach in designing landscape mosaics that provide CES while addressing the need to supply provisioning and regulatory ecosystem services.

文摘Global warming and climate change have made food production through conventional agriculture inefficient, and their effects on livestock and crop cultivation are leading to disruptions in the food supply. The troubles are severe in regions suffering from improper land management and unsustainable practices. The Bio-CircularGreen(BCG) economic model, designed to reduce and recycle resources by using environmentally friendly procedures, has been developed. The Azolla plant represents an interesting model for BCG and for enhancing community networks in Southeast Asia(SEA) because it provides multipurpose materials. Azolla can be used for various applications in agriculture such as biofertilizer and animal feed. However, our understanding and utilization of Azolla are limited. Moreover, collaboration among farmers is insufficient to maximize the benefits of Azolla. In this study, we provide a comprehensive review of the role of Azolla in agriculture. We review the main properties of Azolla as biofertilizers, especially regarding rice production and the interaction with cyanobacteria. For livestock, we discuss procedures to use Azolla in animal feed and evaluate the ingredients of the meal. In addition, we discuss product qualities from livestock treated with Azolla in the diet. This review also describes Azolla-based farming, which is designed for efficient land use and promotes nutrient cycling.Hence, we show that the Azolla plant is one of the key factors for farm-based agroecosystem services which can drive sustainable bioresource management in SEA. Moreover, we also propose the potential development of Azolla to improve its properties as a biofertilizer, a functional feed for animals and humans, and a feedstock for bio-oil production.

文摘Urban forest parks deliver a wide spectrum of ecosystem services that support biodiversity,climate regulation,and public well-being;however,their perceived value among local visitors remains underexplored in Southeast Asia.This study investigates visitor perceptions and economic valuation of ecosystem services at Mount Pulai Forest Eco Park in Johor,Malaysia.Grounded in the Total Economic Value(TEV)framework and ecosystem service theory,the research employed a structured on-site survey of 392 visitors and applied the Contingent Valuation Method(CVM)to assess awareness,appreciation,and willingness-to-pay(WTP)for forest conservation.Findings revealed that visitors highly valued regulating services,such as air purification and flood mitigation(mean≈4.3/5),and supporting services,like biodiversity(mean≈4.2/5),while provisioning services were rated lower(mean≈2.8/5).Despite limited familiarity with ecological terminology,only 33%understood the term“ecosystem services”.In contrast,a substantial majority(79.1%)expressed WTP for conservation efforts,proposing an average annual contribution of MYR 51.32.Additionally,65%of respondents supported an entry fee model,suggesting a mean payment of MYR 3.07 per visit.These results underscore the economic and non-economic value that urban residents assign to forest benefits,offering new insights into conservation finance and public engagement.The study’s innovation lies in its integration of ecosystem perception with economic valuation in an urban forest setting,providing a replicable framework for sustainable park management across Southeast Asia.

文摘Accurately forecasting ecosystem services is critical for enhancing our understanding and improving management practices within nature reserves,particularly in light of climate change,land use/cover changes,and their complex interactions.However,existing studies often fail to fully consider vegetation response,constituting a gap in the comprehensive assessment of changes in ecosystem services.Therefore,a coupled model framework integrating climate change,land use change,and vegetation dynamics was developed to allow for the simulation of dynamic ecosystem service scenarios throughout the twenty-first century.The Jiulianshan National Nature Reserve in Jiangxi Province was considered as the study area.The results showed that ecosystem services and their synergistic effects will be optimized under scenarios that emphasize strict protection of ecological lands and incorporating the SSP1-2.6 scenario.However,sustaining optimized ecosystem services poses significant challenges in scenarios characterized by resource-intensive development and ongoing climate warming,as in the SSP5-8.5 scenario.Notably,discernible variations exist in balancing and synergizing the management of ecosystem services across diverse land uses and forest types.Our study underscores the importance of integrating vegetation response into the framework of ecosystem service forecasting,which is essential for assisting nature reserves in effectively addressing the multifaceted risks associated with climate change and rapid socio-economic development.

文摘Cultural ecosystem services(CES)provided by urban green infrastructure are essential for enhancing social well-being and resilience.Identifying and mapping CES at a local scale is crucial for informed land-use decisions that align with citizens'perceptions.However,research on ecosystem services in Romania has been limited,with a notable gap in the assessment of CES provided by urban green spaces.This study is the first to focus on Băneasa Forest,the only urban forest in Bucharest,which serves as a vital recreational area for thousands of residents and visitors.For the first time in Romania,this research uses a web-based Participatory GIS survey to collect spatially referenced data.The survey,which combines questionnaires and mapping exercises,allows us to produce high-resolution CES maps based on 816 responses.The results reveal that the forest's natural characteristics are perceived as the primary contributors to CES.These findings are valuable for urban planners,as they highlight the needs and expectations of forest visitors,promote conservation efforts,and foster collaboration to prevent conflicts.Alongside factors frequently discussed in the literature,such as age and accessibility,the percentage of green space in residents'neighborhoods emerges as a significant factor influencing CES preferences.This insight presents a novel contribution to the literature,being of particular importance for urban planners and policymakers,as it underscores the need to consider not just the green space within parks and forests,but also the broader context of surrounding neighborhoods when planning for CES.Understanding that the availability of nearby green space influences residents'CES preferences can guide more effective strategies to enhance access to CES in urban areas,both in Bucharest and elsewhere.This is especially relevant in the face of climate change and other emerging challenges,which are likely to increase the demand for CES in the future.

文摘Central Asia(CA)faces escalating threats from increasing temperature,glacier retreat,biodiversity loss,unsustainable water use,terminal lake shrinkage,and soil salinization,all of which challenge the balance between ecological integrity and socio-economic development essential for achieving Sustainable Development Goals.However,a comprehensive understanding of priority areas from a multi-dimensional perspective is lacking,hindering effective conservation and development strategies.To address this,we developed a comprehensive assessment framework with a tailored indicator system,enabling a spatial evaluation of CA’s priority areas by integrating biodiversity,ecosystem services(ESs),and human activities.Combining zonation and geographical detectors,this approach facilitates spatial prioritization and examines ecological and socio-economic heterogeneity.Our findings reveal a heterogeneous distribution of priority areas across CA,with significant concentrations in eastern mountainous regions,river valleys,and oasis agricultural lands.We identified 184 key districts crucial for ecological and societal sustainability.Attribution analysis shows that natural factors like soil types,precipitation,and evapotranspiration significantly shape these areas,influencing human activities and the distribution of biodiversity and ESs.Multi-dimensional analysis indicates existing protected areas cover only 15%of the top 30%priority areas,revealing substantial conservation gaps.Additionally,a 38%overlap between ESs and human activities,along with 63.25%congruence in integrated areas,underscores significant human impacts on ecological systems and their dependency on ESs.Given CA’s limited resources,it is crucial to implement measures that strengthen conservation efforts,align ecological preservation with socio-economic demands,and enhance resource efficiency through sustainable integrated land and water resource management.

文摘Marine protected areas(MPAs)play a critical role in maintaining marine ecosystem health,conserving biodiversity,and sustaining coastal livelihoods and socio-economic benefits.However,MPAs in China still face significant design and management limitations,including a lack of a robust scientific basis for boundary delineation,weak enforcement capacity,poor adaptability to environmental and socio-economic changes,and insufficient integration of the ocean’s three-dimensional characteristics.These limitations are particularly evident in the context of climate change,overexploitation of marine resources,and the complex dynamics of ecosystems.This study systematically reviews the current status and challenges of MPAs in China,with a specific focus on the need for and benefits of dynamic and threedimensional protected areas for marine conservation.Dynamic protected areas,supported by real-time monitoring and flexible boundary adjustments,can more effectively respond to the migratory patterns of marine species and seasonal distribution shifts along China’s coast.On the other hand,three-dimensional protected areas enhance ecosystem protection by incorporating vertical ecological gradients and ocean depth,offering a vital complement to the predominantly two-dimensional protection approach currently in use.The study indicates that,with current technological and data capabilities,effective implementation of these advanced approaches requires precision marine observations,advanced analysis methods,and coordinated efforts among diverse stakeholders.In response,the study synthesizes multiple case studies to illustrate the potential ecological,managerial,and policy-related outcomes of dynamic and three-dimensional MPAs.It proposes strategies for optimization,implementation pathways,and targeted policy recommendations.Ultimately,the study emphasizes the critical role of scientific planning and technological innovation in enhancing the effectiveness of MPAs in China.It calls upon policymakers and the broader society to increase attention and investment in dynamic and three-dimensional marine conservation approaches.This work not only provides a scientific foundation for more precise and efficient marine governance in China,but also lays crucial foundation for achieving ocean-related sustainable development goals aligned with China’s national context.

文摘The relationship between ecosystem services(ES)and human well-being(HWB)is fundamental to the science and practice of sustainability.However,studies have shown conflicting results,which has been attributed to the influences of indicators,contexts,and scales.Yet,another potential factor,which has been overlooked,may be the mixed use of spatial and temporal approaches.Using twelve ES and seven well-being indicators and multiple statistical methods,we quantified and compared the spatial and temporal ES–HWB relationships for Inner Mongolia,China.The spatial and temporal relationships differed in both correlation direction and strength.Most relationships of economic and employment-related indicators with food provisioning and supporting services were temporally positive but spatially nonsignificant or negative.Some relationships of economic and employmentrelated indicators with water retention,sandstorm prevention,and wind erosion were temporally negative but spatially complex.However,the spatial and temporal ES–HWB relationships could also be similar in some cases.We conclude that although both the spatial and temporal approaches have merits,space generally cannot substitute for time in the study of ES–HWB relationship.Our study helps reconcile the seemingly conflicting findings in the literature,and suggests that future studies should explicitly distinguish between the spatial and temporal ES–HWB relationships.

文摘In recent years,there has been a pronounced increase in the frequency of extreme weather events.To compre hensively examine the impact of extreme weather on ecosystem services within the Wuhan Urban Agglomera tion(WUA),this study utilized meteorological station data,the Mann-Kendall(MK)test,and the Standardized Precipitation-Evapotranspiration Index(SPEI)to quantify the variation trends in heatwaves(HW)and droughts from 1961 to 2020.Then the Integrated Valuation of Ecosystem Services and Trade-offs(InVEST)model was employed to evaluate and compare the differences in water yield and climate regulation ecosystem services un der various HW,droughts,and HW-drought combination scenarios.The results show that over the past 60 years,the temperature,duration,and frequency of HW have significantly increased in the WUA.Specifically,the high est HW temperature,total HW days,HW frequency,and average HW temperature showed changing trend of+0.17℃/decade,+1.4 day/decade,+0.19 event/decade,and+0.07℃/decade,respectively.The year 2000 was identified as a mutation year for HW,characterized by increased frequency and heightened severity thereafter.The SPEI value exhibited an insignificant upward trend,with 1980 marked as a mutation year,indicating a de creasing trend in drought occurrences after 1980.Heatwaves have a weakening effect on both water yield and climate regulation services,while drought significantly weakened water yield and had a relatively modest effect on climate regulation.During HW-drought composite period,the average monthly water yield showed a notable discrepancy of 60 mm compared to humid years.Besides,as heatwaves intensify,the area of low aggregation for ecosystem services expands,whereas the area of high aggregation decreases.This study provides a preliminary understanding of the impact of urban extreme weather on urban ecosystem services under changing climatic conditions.

文摘Exploring the spatial heterogeneity of ecosystem services(ESs)and their driving factors under various interaction patterns is essential for informing sustainable development policies.Using Northeast China as a case study,this research investigates eight key ESs,including water yield(WY),carbon storage(CS),food provision(FP),habitat quality(HQ),soil conservation(SC),wind-break and sand-fixation(WS),water purification(WP)and aesthetic landscape(AL).The study examines the complexity of ESs from three dimensions:individual ES,ES pairs and ES bundles,and further evaluates their spatial heterogeneity and socioecological drivers.The results indicate that the spatial distribution of ESs remained relatively stable from 2000 to 2020.During this period,WY and FP increased significantly,CS and HQ remained relatively unchanged.SC,WS and AL followed an“increase-decrease-increase”trend,and WP exhibited a“decrease-increase”fluctuation.Overall,synergistic relationships among ES Pairs were more prevalent than trade-offs.Notably,CS showed trade-offs with over 70%of the other ESs,while HQ exhibited trade-offs with SC,WS,WP,and AL.The FP-HQ synergy bundle,primarily located in the Greater Hinggan Mountains and eastern regions,emerged as the dominant ES bundle.Ecological factors—such as solar radiation,temperature,slope,DEM,and NDVI—exerted a stronger influence on ES patterns than social factors like GDP and population density.Furthermore,these ecological drivers had a greater impact on individual ESs compared to ES pairs or ES bundles.These findings offer valuable insights for policymakers to understand the complex interrelationships among ESs and to design more effective and regionally tailored management strategies.

文摘The application of ecosystem services(ES)theories in land consolidation is a confusing issue that has long plagued scholars and government officials.As the upgraded version of traditional land consolidation,comprehensive land consolidation(CLC)emphasizes ecological benefits,but it does not achieve the expected effect during the pilot phase.This study first proposed a theoretical analysis framework based on ES knowledge to answer the three key questions of why,where,and how to implement CLC better.Taking mountainous counties as the study area,we found that ES trade-offs/synergies,bundles,and drivers were significantly affected by scale effects.ES knowledge can play a crucial role in designing multi-scale CLC strategies regarding the objective,zoning,intensity,and mode.Specifically,mitigating the significant trade-offs between recreational opportunities,food production,and other ES is the top priority of CLC.Land consolidation zoning based on the ES bundles analysis is more rational and can provide the scientific premise for designing locally adapted CLC measures.Land consolidation can be classified into high-intensity direct intervention and low-intensity indirect intervention modes,based on the major drivers of ES.These findings help narrow the gap between ES and CLC practices.

文摘The Kulpawn River Basin(KRB)plays a critical role in supporting rural livelihoods through agriculture,water supply,and biodiversity conservation.However,between 1995 and 2023,significant land use and land cover(LULC)changes have been observed,affecting ecosystem services(ESs).This study evaluated the ecosystem service values(ESVs)associated with LULC changes.The random forest algorithm was applied to extract LULC information from Landsat images for 1995,2005,2015,and 2023.The benefit transfer method was employed to estimate the ESVs over the study period.Questionnaires were also used to assess the views of respondents on the drivers of the ES changes in the basin.The results showed that agricultural lands expanded by 14.14%,built-up areas by 15.17%,and light savannah forest by 8.73%,while dense savannah forest and water bodies declined by 25.71%and 20.00%,respectively.The total estimated ESV was 410.09×10^(8),362.92×10^(8),335.30×10^(8),and 319.28×10^(8) USD/(hm^(2)·a)in 1995,2005,2015,and 2023,respectively,indicating that the total ESV declined from 410.09×10^(8) USD/(hm^(2)·a)in 1995 to 319.28×10^(8) USD/(hm^(2)·a)in 2023.The study concludes that the reduction in ESVs is due to the LULC changes resulting from agricultural activities,expansion of built-up areas,population sprawl,and artisanal mining activities.Hence,there is an urgent need to develop programs and strategies to mitigate and curtail the degradation of LULC and ESVs in the basin.These findings reveal a growing ecological vulnerability,threatening water security and rural livelihoods.The study offers valuable insights to guide sustainable land use planning and ecosystem conservation strategies.

文摘Land use sustainability is a pivotal concern in contemporary ecological protection efforts,necessitating a comprehensive understanding of the ramifications of changes in land use intensity(LUI)on ecosystem services(ESs).Although ecological control zoning typically emphasizes ES outcomes,it tends to overlook the impacts of human activity intensity.This research focuses on the Yellow River Basin and integrates various data sources,encompassing land use,meteorological,soil,and socioeconomic data from 1980 to 2020.Using the InVEST model,quadratic polynomial fitting,and cluster analysis,this work evaluates the spatiotemporal changes and zoning characteristics of LUI and three ESs—water yield,soil conservation,and habitat quality—to explore the influence of LUI changes on ESs.The results indicate that from 1980 to 2020,LUI shows a sustained increase with considerable spatial heterogeneity,gradually intensifying from upstream to downstream areas.The interannual variability of ESs is minimal,with substantial local fluctuations but overall minor changes.LUI correlates positively with ESs.Based on regional ESs,the Yellow River Basin is categorized into four primary ecological function zones:ecological restoration,ecological pressure,ecological sustainability,and ecological conservation.Considering LUI characteristics,this categorization is further refined into six secondary function zones:ecological restoration,ecological transition,ecological overload,potential development,eco-economic carrying,and ecological conservation.This study provides a scientific foundation for land use planning and ecological conservation policy formulation within the watershed area.
