-
Based on the remote sensing monitoring data according to land use status of 2000, 2005, 2010 and 2017, Nanchang City was taken as an example site. Diversity index, GIS spatial analysis and ecological value evaluation model were used to analyze the impact of land use change on ecosystem service value of Nanchang in the period 2000—2017. The results show that:(1)from 2000 to 2017, due to the rapid growth of construction land, the cultivated land and forest land decreased, the overall value of ecosystem services in Nanchang showed the decreasing trend; the value decreased from 3.756 9×1010 yuan in 2000 to 3.574 7×1010 yuan in 2017; and the aquatic ecosystem was the main provider of ecosystem services in Nanchang;(2)affected by the change of land use, the change of ecosystem service value in Nanchang showed obvious regional difference; these changes seemed to be obvious in Jinxian County; and regulating service function was the main function of land ecosystem in Nanchang which accounted for more than 67.59% of the total value of land ecosystem services in Nanchang and mainly distributed in Jinxian County and Xinjian County; the lowest regulation service function value(3.8×107 yuan)was found in Qingyunpu distric; towns or streets with lower regulation service function and cultural function mainly distributed in the central urban and the area around it of Nanchang;(3)the value of ecosystem services in each administrative town of Nanchang was negatively correlated with the area of construction land; the excessive increase of construction land affected the increase and decrease of ecosystem service value. These results can provide the basis and reference for the future ecological environment construction and development of Nanchang City.
