通过构建水利绿色发展指数测算模型, 对 2017 年我国 31 省( 自治区、直辖市) 水利绿色发展水平进行了评价, 并引入空间自相关和空间热点探测分析法对我国水利绿色发展水平的空间相关性和异质性进行分析, 从准则层和指标层识别水利绿色发展空间分异的主控因子。结果表明: 我国水利绿色发展水平整体呈现东部高于西部 的态势, 优良等级的省份主要位于我国华北和华东地区; 我国水利绿色发展水平在空间上呈现较强的异质性, 热点区包括北京和天津两市, 冷点区包括新疆、西藏、青海、甘肃和黑龙江等 5 省( 自治区) ; 水利绿色发展水平空间差异主要受水土流失治理率、水利信息化水平、生态用水比例、生产用水综合经济效率和大专以上管理人员比重等指标影响较大。

A calculation model is established to evaluate the level of water conservancy green development in 31 provinces ( autonomous regions or cities) of China in 201 7. S patial autocorrelation and spatial hotspot detection are introduced to analyze the spatial heterogeneity of China's water conservancy green development level. The dominant factors are identified from the criterion and the index level. T he results showed that: The water conser vancy green development level is higher in the east than in the west, and the provinces with ex cellent grades are mainly distributed in north and east China; The level of water conservancy green development in China showed strong hetero geneity in space, and the hot spots of water conservancy green development levels are distributed in Beijing and Tianjin, while the cold spots are located in Xinjiang , Tibet, Qing hai, Gansu, and Heilong jiang provinces or antonomous regions; The spatial differ ence of water conservancy green development level is greatly influenced by soil erosion control rate, water conservancy inform atizatio n level, ecological water use ratio, comprehensive economic efficiency of production water use, and the proportion of managers above co llege level have a greater impact.
