摘要: 在模糊物元分析的基础上,结合欧氏贴近度的概念,提出了基于欧氏贴近度的模糊物元分析方法.在对区域水资源可持续利用进行综合评价时,把各地区各开发利用阶段作为物元的事物,以它们的各项评价指标及其相应的模糊量值构造复合模糊物元,通过计算与标准模糊物元之间的欧氏贴近度,并采用层次分析法计算各评价指标的权重,实现对各地区水资源可持续利用的综合评价与排序.该模型被应用到西安市的水资源可持续利用综合评价中,取得了较好的效果,对西安市水资源的可持续利用具有重要的指导意义.Abstract: In order to evaluate regional water resources sustainable ut ilization,the paper puts forward a new method on the basis of the fuzzy matter-element analysis and combined with the concept of Euclid approach degree,regarding the regional samples and the utilization phases as the object of mater-element and constructs the compound fuzzy mater-element with the evaluation factors and their fuzzy value of the object.Through calculating Euclid approach degree between the fuzzy matte-relement and the standard(the best)fuzzy matte-relement,the writer achieves on development and utilization phase of regional water re-sources and its optimum order,with the calculation of weight adopting the analytical hierarchy process method and the model applied to the evaluation of water resources sustainable utilization in Xi'an.It provides significant reference for sustainable development of water resources in Xi'an.
