以松辽流域水资源量与用水状况为例,选择相应的水资源利用效率指标,构建了基于熵权的水资源利用效率综合评价方法,给出了各行政区水资源利用效率综合评价指数,并分析了水资源利用效率相对差异的成因。结果表明,该方法为解决水资源短缺、缩小区域水资源利用效率差异与制定合理的水资源决策提供了参考。
Taking the quantity of water resources and water use in Songliao basin as an example, this paper selects the corresponding indexes of water resources utilization efficiency, constructs a comprehensive evaluation method of water resources utilization efficiency based on entropy weight, and gives the comprehensive evaluation index of water resources utilization efficiency in all administrative districts The causes of the relative differences in water use efficiency are analyzed. The results show that this method provides a reference for solving the shortage of water resources, narrowing the difference of utilization efficiency of regional water resources and making rational water resources decision.
