The purpose is to explore the coupling of human development system and natural ecosystem, and to analyze the comprehensive driving force of ecosystem service value. The study makes the assessment and comparison of the ecosystem service values, and explores the influencing factors. Using the two phases of land use data interpreted from Landset TM/ETM high-resolution satellite images in 2010 and 2017, this study applies coefficient correction equivalent factor method based on NPP to calculate the local ecosystem service value. The results show that:(1)the ecosystem service value showed an increasing trend, with Hubei, Hunan and Jiangxi presenting different magnitudes;(2)among all types of land, the ecosystem service values of water and woodland were the greatest, followed by cultivated land and grassland, which have an increasing trend; the ecosystem service value of unused land was the smallest, which had decreased;(3)the ecosystem service value at the county level showed significant spatial autocorrelation; it was affected by patch density, the proportion of the added value of the tertiary industry, and the per capita disposable income of urban residents; the impact of the three on ecosystem services was negative, of which per capita disposable income of urban residents had the greatest negative impact. By avoiding high-density and fragmented development, and protecting important ecological function areas, the value of ecosystem services can be improved, and the construction of ecological civilization in the Yangtze River Economic Zone can be promoted.
