Priority protected area and drivers of ecosystem services from supply-demand perspective:taking the loess gully area of the Yellow River basin as an example
Understanding the matching relationship between ecosystem service(ES)supply and demand,and identifying the socio-ecological drivers of regional differentiation is considered crucial for sustainable ecosystem management.Taking the loess gully area of the Yellow River basin as a case study,this study evaluated the supply and demand of four key ES,namely food production service,water yield service,soil conservation service and carbon sequestration service.Then,the identification framework of ES priority protected areas was constructed from the perspective of temporal and spatial stability.Subsequently,this study compared and analyzed the differentiated socio-ecological driving mechanism inside and outside the priority protected area.The results showed that during the study period,all other ES were in short supply except for food production service.Among them,the supply and demand deficit of water yield and soil conservation service decreased,while the supply and demand deficit of carbon sequestration service increased significantly.The ES priority protected area was mainly located in the southeastern region of the loess gully area,with the counties in the loess tableland gully region as the main focus.The variation of ES supply and demand relationship were dominated by population density and rainfall in priority protected area,and by economic density and rainfall in other areas.The research results contributed to the development of differentiated ecological protection strategies according to local conditions,thereby promoting the improvement of the matching relationship between ES supply and demand.
