Scientific calculation of appropriate ecological compensation standards and the establishment of a sound long-term mechanism for ecological compensation are key elements in promoting high-quality ecological civili-zation construction in national parks.Based on the land use change of Nanshan National Park,the ecosystem serv-ice value is measured by using the ecosystem service value correction model,and then the spatial difference of the evolution of ecosystem service value is described by using the ArcGIS spatial analysis method.Finally,the priority of ecological compensation in each county within the region is comprehensively calculated,and the regional ecologi-cal compensation standard is designed.The results indicate as follows.(1)From a time series perspective,the eco-system service value of Nanshan National Park shows a trend of first decreasing and then increasing,but overall it has shown a downward trend from ten years ago to now.The forest ecosystem service value is the highest,account-ing for 98％of the total value.(2)From the perspective of spatial evolution,the ecosystem service value of each county under the jurisdiction of Nanshan Gongjia Park,from high to low,is as follows:Chengbu Miao Autonomous County,Suining County,Xinning County,Dong'an County.(3)The priority of ecological compensation in each county is:Suining County,Chengbu Miao Autonomous County,Xinning County,Dong'an County;The total eco-logical compensation amount for Nanshan National Park is 480 million yuan,with a decreasing order Chengbu Miao Autonomous County,Suining County,Xinning County,Dong'an County.
