Abstract:Jiangsu province has low resources and environmental capacity, but its economy is developing rapidly. Carrying out change research on land use, ecosystem service and ecosystem service value in time and space, under the background of sustainable development, can provide theoretical basis for opening scientific land improvement to reduce regional economic differences. First of all, analysis of land use change situation based on 1995-2015 economic development important time of the node in the study area of land use/cover change (LUCC) data, then introduce assessment and scoring theory to dynamically study changes in ecosystem services, at last, by modified equivalent factor calculation value of ecosystem services and application of spatial autocorrelation analysis method to study the change of ecosystem service value in time and space with the hot spot. The results show that:(1) cultivated land, construction land and water are the main land use types in the study area, and the total coverage is more than 90%;2005-2015 has rapid land use change and the land use in southern part of jiangsu is rich.(2) compared with different landscape types, forest is an ecosystem with more functions; In 2015, the total score of functional attributes was higher than that of 1995, but the ecological function score decreased from 5 to 2 points.(3) Ecosystem services value in Jiangsu Province decreased from 125.189 billion yuan to 120.874 billion yuan and that in southern Jiangsu changed greatly from 1995-2015. It is predicted that by 2022, ESV will fall to 135 million yuan; the value of ecosystem services in southern Jiangsu has changed significantly.
