杭州市水资源开发利用阈限分析的综合评价

Comprehensive evalution on development of water resources by utilizing limit analysis in Hangzhou City

基于模糊数学理论的区域水资源开发利用阈限分析方法,选取灌溉率、产水系数、水资源开发程度、供需水模数、人均供水量和生态用水率7个主要因素作为评价因素,以杭州市区为例进行具体计算与分析。评判结果表明,杭州市区水资源开发已经达到相当的规模,在水资源开发过程中,处于过渡阶段。

Based on the principle of fuzzy, utilizing the comprehensive evaluation model of limit analysis on the development of water resources, the authors selected evaluation factors include irrigation ratio of total land, coefficient of product water, degree of water exploitation, water supply and demand modulus, per capita water supply and ecological water use ratio to analyze. The results show that the water resources development in the studied area has reached a corresponding scale, which has represented a stage of transition.
