武汉市水资源可持续利用评价

QUANTITATIVE EVALUATION ON THE SUSTAINABLE APPLICATION OF WATER RESOURCE IN WUHAN CITY

水作为人类所需要的不可替代的一种自然资源,是社会经济持续发展的重要支撑之一。解决武汉市的水问题,直接关系到武汉市人民群众的生活,关系到社会的稳定,关系到城市的可持续发展。采用定量方法———层次分析法和综合指数法对武汉市水资源进行评价,找出近几年来武汉市水资源持续利用的趋势,为武汉市水资源的可持续利用提供可靠的依据。具体步骤是:首先采用层次分析法确定武汉市水资源可持续利用评价指标体系;其次,对武汉市各年代水资源评价指标分别赋值、确定权重;其三,按照加权相加的方法(即综合指数法)评定出武汉市各年代水资源利用得分;最后根据各年代分值的大小进行对比分析,得出武汉市水资源利用变化趋势。

Water is a sort of natural resource that can't be replaced. It is also one of the important supports for the sustainable development of the society and economy. Solving the water problem of Wuhan is benefi- cial to the life of the people, the stability of the society and the urban sustainable development. By using quantitative evaluation method, this paper examed the situation of the sustainable application of water re- source in Wuhan city and found out the better and worse aspects in this city. The purpose is to provide the scientific basis for the sustainable use for Wuhan's water resources. The concrete steps are: firstly, the in- dex system of evaluation is determined; secondly, the weight of each index is determined, and the indexes of each time period are arranged in order in their actual value and the comparative values are given out. Thirdly, the marks of each time are worked out by weighted sum (it also names the method of synthetical- ly index). The end, the order of the water application level is worked out by comparing the marks of each time. By comparing with each index and analyzing the comparatively better and worse index within each time, the author gives a quantitative and overall evaluation. That is a quantitative evaluation.
