基于生态系统服务供需的社会-生态安全格局构建
Construction of socio-ecological security pattern based on the supply and demand of ecosystem services:A case study of the Loess hilly and gully region
摘要
Abstract
The balance between ecosystem service(ES)supply and demand underpins ecological security,making the construction of ecological security patterns(ESPs)integrating ES supply-demand dynamics with human well-being critical for regional sustainability.However,existing studies often focus on single administrative units or static assessments while oversimplifying ecological resistance surfaces,inadequately reflecting the complexity of securing ecological well-being and resulting in ESPs with limited resilience and adaptability.To address this,we propose a novel method for constructing social-ecological security patterns by coupling ES flows with supply-demand ratios.Applying this approach to China' s ecologically fragile Loess hilly and gully region,we integrated the Gaussian two-step floating catchment area method and circuit theory to refine traditional resistance surfaces,establish dedicated supply-demand corridors and nodes,and formulate a holistic,synergistic security pattern.The results revealed:(1)a spatially heterogeneous ES supply("high southeast,low northwest")contrasting with demand exhibiting"linear clustering and scattered distribution",where water conservation and soil retention faced the most severe deficits;(2)identification of 67 ecological source areas(10,776.87 km2),33 demand source areas(1,632.27 km2),7,480.64 km of ecological corridors(demonstrating higher network efficiency in the southeast),8,991.5 km of supply-demand corridors,82 ecological nodes,and 9 supply-demand nodes;and(3)development of a spatial framework termed"four belts,four zones,one barrier,and three clusters",accompanied by targeted conservation-restoration strategies to reconcile ecological protection with economic development.This study provides a scientific foundation for advancing sustainable economic growth and human well-being in the Loess hilly and gully region.关键词
