基于改进熵权法的水资源承载力评价——以曲陆坝区为例
Evaluation of water resources carrying capacity based on improved entropy weight method:A lase study in Qulu dam area
摘要
Abstract
Water resource is one kind of strategic natural resource, which is of great significance for the maintenance of regionally ecological security and sustainable development of society and economy.Based on the fuzzy comprehensive evaluation model of water resources, this paper makes use of the rank ratio method and the minimum relative entropy principle to improve the traditional entropy weight method.Based on the coupling of objective and subjective factors and considering the regional characteristics, 14 evaluation indicators were selected to evaluate the water resources carrying capacity of Qu Lu dam area of five level years.The results show that in the case of no water transfer, the comprehensive evaluation of water resources carrying capacity are 0.479, 0.390, 0.335, 0.287,and 0.283, respectively.in the case of water transfer, the water resources carrying capacity of five years of Qu Lu dam area are 0.446, 0.367, 0.323, 0.351, and 0.365, respectively, which indicates water resources carrying capacity can be improved significantly by external basin water transfer.关键词
