多维胁迫下陕西省县域生态系统健康演变机制与协同治理
Evolution mechanism and collaborative governance of ecosystem health at county-level in Shaanxi Province under multi-dimensional stress:a configuration analysis based on GTWR and fsQCA
摘要
Abstract
The health status of ecosystems determines regional water conservation,soil and water conservation,and climate regulation.Underpressures such as exploitative resource development,pollutant emissions,and extreme climate change,ecosystems face degradation risks.Assessing ecosystem health and its influencing mechanisms is crucial for balancing economic development and ecological governance.Based on the Vigor-Organization-Resilience-Service(VORS)model,this study evaluated the county-level ecosystem health index in Shaanxi Province from 2000 to 2022.A driver system was constructed from economic,natural,and social dimensions,and key driving factors were identified using Random Forest,AdaBoost,GBDT,and XGBoost models.The spatiotemporal heterogeneity between these factors and ecosystem health was revealed through Geographically and Temporally Weighted Regression(GTWR).Fuzzy-set Qualitative Comparative Analysis(fsQCA)was further employed to explore configurational patterns affecting ecosystem health.The results exhibited that:(1)From 2000 to 2022,the overall ecosystem health in Shaanxi Province showed an improving trend,with the mean value rising from 0.478 to 0.528,and spatially presenting a pattern of"better in the south,worse in the north."(2)The influence of each driving factor on ecosystem health exhibited significant spatiotemporal heterogeneity.Precipitation exerted a positive effect,while fiscal revenue/expenditure,impervious surface ratio,and population density had negative effects.The impact of the proportion of primary industry added value in GDP shifted from negative to positive.The influence of slope changed from positive to negative in northern Shaanxi,while it remained positive in the Guanzhong and southern Shaanxi regions.(3)Ecosystem health was affected by the concurrent influence of multiple conditional variables.The pathways promoting ecosystem health were mainly"nature-dominated,""economy-nature-dominated,"and"economy-nature-society jointly dominated,"whereas configurations associated with low ecosystem health were primarily"society-dominated,""nature-society-dominated,"and"economy-society-dominated."The findings provided a scientific basis for zonal ecosystem conservation and management in Shaanxi Province.关键词
