利用DMSP/OLS、NPP/VIIRS和Landsat遥感影像数据分别提取平均夜间灯光数据和生态环境指数，利用熵值法建立综合经济指数，构建耦合协调发展模型定量分析南昌市2003—2018年的城市化、经济与生态环境耦合协调关系。结果表明：(1)2003—2018年期间，南昌市生态环境指数（remote sensing-based ecological index,RSEI）、夜间灯光指数（nighttime light index,NLI）以及综合经济指数总体呈上升趋势，随着社会经济的发展，区域生态环境质量逐渐改善；(2)城市化水平、经济发展以及生态环境质量3个系统的耦合协调度不断提高，耦合协调状态由2003—2013年的初级协调发展向2013—2018年的良好协调发展转变。

Using DMSP/OLS, NPP/VIIRS and Landsat remote sensing image data, the average nighttime light index and ecological environment index are extracted respectively.Entropy method is adopted for establishing integrated economic indicators. The coupling coordination degree model is constructed to quantitatively analyze the coupling coordinated relationship among urbanization, economy and ecological environment in Nanchang city from 2003 to 2018. The results show that:(1)During 2003-2018,the remote sensing-based ecological index(RSEI), nighttime light index(NLI) and comprehensive economic index of Nanchang showed an overall upward trend. With the development of social economy, the regional ecological environment quality is gradually improving, and the regional ecological environment quality was improved gradually with socio-economy development.(2) The degree of coupling and coordination of the three systems of urbanization level, economic development, and ecological environment quality continues to increase, and the status of coupling coordination has changed from the primary coordinated development in 2003-2008 to the favorably coordinated development in 2013-2018.
