Abstract： Identifying priority areas for ecological compensation under soil and water conservation is animportant reference for establishing a suitable compensation system to support local ecological development. Inthis study, the Ningxia Hui Autonomous Region is taken as the study area, and the InVEST model is employed toevaluate three major soil and water conservation service functions: water connotation, soil conservation, andcarbon storage. Their respective value amounts were assessed. Additionally, the ecological compensation priorityand ecological vulnerability index of each district and county are considered to conduct a spatial identification ofpriority areas for ecological compensation for soil and water conservation in Ningxia. Research has shown thatthe value of soil and water conservation in Ningxia has steadily increased each decade from 2000 to 2020,reaching 247.89 billion yuan, 266.17 billion yuan, and 295.85 billion yuan, respectively. Geographically, thesouthern regions generally exhibit higher values, whereas the northern regions show lower values, with JingyuanCounty, Guyuan City, and Jinfeng District, Yinchuan City, representing the highest, and lowest values,respectively. Over the years, the priority compensation areas for soil and water conservation have experiencedrelatively minor changes. These areas are mainly located in the southern regions, characterized by high ecologicalvalue but economic backwardness. The secondary priority areas for ecological compensation are located in thecentral and northern regions, characterized by low ecological value but high economic development.Compensating these priority areas can effectively improve the efficiency of ecological compensation, foster theregional ecological environment, and promote sustainable economic, and social development.
