摘　　要：基于DSR生态系统质量概念模型,构建了一个大湖流域地区生态质量评价指标体系,运用面板数据熵权法对2001—2013年洞庭湖流域14个地区的生态质量水平进行了综合评价。结果显示:近十多年来洞庭湖流域总体生态质量在中等水平附近波动并略有提升,波幅收窄呈空间趋同势头;其中湘江水系区域生态质量低于全流域平均水平,资江、沅江和澧水水系区域生态质量均高于全流域平均水平;水质变化和雾霾扩散是导致近几年洞庭湖流域地区生态质量波动的主要原因。Based on basin ecology quality evaluation index system and panel data entropy weight method, we access the 14 regions＇ performance around Dongting Lake during 2001-2013. The result reveals： （a） The urban ecology quality in Dongting Lake basin experienced a wave rising proceed around middle level and showing amplitude narrowing and spatially convergence. （b） The ecology quality of Xiang River basin is lower than average, Zi River, Yuan River and Li River is higher than average. （c） The slightly drop-down of the hold basin is mainly due to the water quality change and the spread of PM2.5 smog. The main ways to improve the urban ecological quality in the Dongting Lake basin include： Controlling industrial pollution in the Xiangjiang River Basin, agricultural non-point source pollution around the Dongting Lake area and the pollution of the mining industry in Xiangxi area.
