洞庭湖是中国第二大淡水湖泊，是长江经济带重要组成部分，论文以湖南境内洞庭湖区水环境治理绩效为研究对象，基于改良PSR框架模型，筛选14项水环境相关指标构建湖区水环境治理绩效指标体系。测算2010—2019年21个“县域单元”水环境治理水平。结果表明：（1）准则层中权重值由大到小依次为状态值（0.462）、压力值（0.285）、响应值（0.253），表明水环境治理过程中，状态环境是最能反映治理绩效。（2）湖区水环境治理总体呈现良好趋势，但不明显，年均增长率区间为（-0.92%～1.92%），说明治理力度即响应水平还有待提升。（3）洞庭湖区水环境治理绩效呈现出“东西两边高中部低”整体趋势，远...

As the second largest fresh water lake in China and an important part of the Yangtze River Economic Belt,Dongting lake Basin is 14%of the Yangtze River Basin.Taking the water environment of Dongting Lake in Hunan Province as an example,based on the improved PSR framework model,this paper establishes the performance index system of water environment governance in the lake area,which consists of 14 indicators.The water environment governance level of 21 county units from 2010 to 2019 was calculated by entropy weight method and weighted summation ...
