生态系统服务权衡及其影响因素
Tradeoffs of ecosystem services and their influencing factors:A case study of the Shanxi Section of the Yellow River Basin
摘要
Abstract
This study is based on the integrated valuation of ecosystem services and tradeoffs model,which quan-tifies the supply and demand of ecosystem services.This model uses root-mean-square deviation to quantify the intensity of tradeoffs in ecosystem services and analyze the driving factors of tradeoff intensity using a structural equation model.Results show that from 2000 to 2020,the tradeoff intensity of water yield(WY)and soil conser-vation(SC),as well as WY and carbon sequestration(CS)supply,increased.However,the demand coordination intensity of WY and SC services,as well as WY and CS services,decreased.Except for WY services,which had a supply-demand tradeoff intensity greater than 0 in 2020,the supply-demand tradeoff intensity for WY,SC,and CS services was less than zero from 2000 to 2020.The tradeoff and synergy of ecosystem services are primarily influenced by natural factors.Evapotranspiration has a positive effect on the tradeoff between water production and SC services,as well as on the tradeoff between supply and demand for water production and CS services.However,it has a restraining effect on the tradeoff between supply and demand for water production services.The proportion of grassland area has a restraining effect on the tradeoff between water production and CS servic-es,as well as on the synergy between water production and SC service demands.In addition,it has a promoting effect on the supply-demand tradeoff of CS services.Precipitation has a restraining effect on the synergy between water production and CS service demands,as well as on the tradeoff between supply and demand for SC services.However,it has a promoting effect on the tradeoff between supply and demand for water production services.So-cioeconomic factors have a secondary effect on the tradeoff and synergy of ecosystem services.Population densi-ty has a promoting effect on the synergy between water production and soil conservation service demands,where-as it has a restraining effect on the tradeoff between supply and demand for water production services and CS ser-vices.Therefore,when developing comprehensive management decisions for river basins,the spatial characteris-tics and driving factors that contribute to the tradeoff and synergy of ecosystem services must be considered.关键词
