摘      要：Ecosystem services,which include water yield services,have been incorporated into decision processes of regional land use planning and sustainable *** pattern characteristics and identification of factors that influence water yield are the basis for decision ***,there are limited studies on the driving mechanisms that affect the spatial heterogeneity of ecosystem *** this study,we used the Hengduan Mountain region in southwest China,with obvious spatial heterogeneity,as the research *** water yield module in the InVEST software was used to simulate the spatial distribution of water ***,quantitative attribution analysis was conducted for various geomorphological and climatic zones in the Hengduan Mountain region by using the geographical detector *** factors,such as climate,topography,soil,vegetation type,and land use type and pattern,were taken into consideration for this *** key findings were ***,water yield spatial heterogeneity is influenced most by climate-related factors,where precipitation and evapotranspiration are the dominant ***,the relative importance of each impact factor to the water yield heterogeneity differs significantly by geomorphological and climatic *** flat areas,the influence of evapotranspiration is higher than that of *** relief increases,the importance of precipitation increases and eventually,it becomes the most influential *** is the most influential factor in a plateau climate zone,while in the mid-subtropical zone,precipitation is the main controlling ***,land use type is also an important driving force in flat ***,more attention should be paid to urbanization and land use planning,which involves land use changes,to mitigate the impact on water yield spatial *** fourth finding was that a risk detector showed that Primarosol and Anthropogenic soil areas,shrub areas,and areas with sl
