摘要
构建了黄河流域水资源利用效率评估指标体系,建立基于TOPSIS模糊物元-熵权的综合评估模型,并应用Moran’s I指数对黄河流域各省(区)综合水资源利用效率进行空间分异研究。研究结果表明:流域整体水资源利用效率呈现自西向东的递增趋势,山东与河南的水资源利用效率处于良等级,山西、陕西、青海、内蒙古、甘肃与四川处于中等级,宁夏为差等级。各省(区)水资源利用效率表现出相似性的空间集聚。研究成果对于正确理解黄河流域水资源利用效率及其空间分布提供参考。
Both the comprehensive evaluation model based on TOPSIS fuzzy matter-element and entropy theories and Moran's I are applied to study the comprehensive water use efficiency in the Yellow River Basin.The results show that the water use efficiency showed increasing tendency from west to east in the Yellow River Basin.Shandong and Henan are at a good level,that of Shanxi,Shaanxi,Qinghai,Inner Mongolia,Gansu and Sichuan are medium,that of Ningxia is poor.There is a positive spatial correlation of water use efficiency among provinces.The research results have provided reference for the correct understanding of water use efficiency and spatial distribution in the Yellow River Basin.
