基于极大熵的山东半岛城市群水资源承载力评价

Carrying Capacity Assessment of Water Resources in Cities of Shandong Peninsula Based on Maximum Entropy

综合考虑了经济、社会、环境三方面,选取影响半岛城市群水资源承载力的9项指标,用熵值法对其进行赋权,用极大熵原理计算出各城市的水资源承载力,并计算出各市水资源承载力的综合得分。结果表明:日照市、威海市和烟台市水资源承载力为1级,东营市水资源承载力为3级,其余4市的水资源承载力均为2级。山东半岛城市群水资源承载力总体状况良好,但今后应努力发展节水产业,改变用水结构,实现经济与环境协调发展。

Taking Shandong Peninsula urban agglomeration as an example,the paper selected nine indexes on the basis of economy society and environment,then used the entropy method to empower the components,computed the water resources carrying capacity based on maximum entropy and obtained the scores of water resources carrying capacity of each city.The results indicated that the carrying capactity of water resources of the cities such as Rizhao,Weihai and Yantai was the first grade,that of Dongying was the thire grade,the capacity of the rest four cities was the second grade.The carrying capacity of Shandong peninsula urban agglomeration was in good condition,but still we should make great efforts to develop water-saving industry and to reasonably change the structure of water use so as to realize the harmonious development of economics and environment.
