摘　　要：The trade-offs and supply-demand relations of ecosystem services(ES)are at the frontier of geographical and ecological studies.However,previous studies have focused on either trade-offs or the supply-demand aspects,while ES conflicts and supply/demand contradictions have not been comprehensively examined.The relation-ship between ES trade-offs and supply-demand is logically valid and studying the coupling of both can provide approaches for simultaneously alleviating ES conflicts and supply-demand contradictions.This study,based on a review of previous analyses of ES trade-offs and supply-demand dynamics,proposes a new analytic framework to couple them.First,we define two types of trade-offs based on the directions of growth or decline of the two ser-vices.We also define the supply-demand balance area and the supply-demand risk area according to the ES flow characteristics.Second,the mechanisms driving ES trade-offs are clarified,and land-use scenarios are set based on the mechanisms.Third,the supply-demand spatial characteristics of ES are analyzed,and supply-demand risk areas are identified.Finally,scenario iterations are performed to minimize the supply-demand risk area at an acceptable trade-offintensity to identify an optimal land use plan,which simultaneously alleviates ES conflicts and supply-demand contradictions.This analytic framework offers new opportunities for improving sustainable ecosystem management.
