Abstract:: The most effective way to understand the change of regional ecological service value is to study its change and driving factors. Nanchang City was taken as an example. RS and GIS techniques were used to obtain land use data according to the remote sensing images of 2000, 2005, 2010 and 2015. Then, the spatial and temporal characteristics of ecological service values in recent 15 years were studied by revising the ecological service value coefficients of different land use types in the study area. The driving factors and the differences of ecological service values were analyzed by STIRPAT model and geo-weighted regression model. The results show that:in the past 15 years, the ecological service values in Nanchang had changed little, and the total had increased from 3.903 5×10¹⁰ yuan in 2000 to 3.933 0×10¹⁰ yuan in 2015; the high ecological service value areas mainly distributed in the east of Xinjian County and north of Jinxian County, while the low section mainly distributed in the center of Nanchang. The major driving factors of ecological service value (ESV) change are the total population, the proportion of the third industry and the total energy consumption per capita which have a negative correlation with the per capita ESV. There were own driving factors of ESV in different periods, and each factor had its own influence. By analyzing the driving factors of the ecological service value of each district, the influences and born pressures of the driving factors in different regions of Nanchang were different.
