模糊物元模型在新疆农业水资源可持续利用评价中的应用

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。该模型被应用到新疆农业水资源可持续综合评价中,取得了较好的效果,对新疆水资源的开发具有重要的指导意义。

Fuzzy Matterelement Model for Evaluating Sustainable Utilization of Agriculture Water Resources in Xinjiang

In order to eva1uate regional water resources sustainab1e utilization,a new method on the basis of the fuzzy matter element ana1ysis is put forward combined with the concept of Euc1id approach degree,regarding the regional samp1es and the uti1ization phases as the object of matter e1ement and constructs the compound fuzzy matter element with the evaluation factors and their fuzzy va1ue of the object.Through ca1cu1atilg Euclid approach degree between the fuzzy matter element and the standard(the best) fuzzy matter element,the authors achieve on development and uti1ization phase of regional water resources and its optimum order,with the ca1culated weight adopting the ana1ytica1 hierarchy process method and the model applied to the eva1uation of water resources sustainable uti1ization in Xinjiang.It provides significant reference for sustainable development of water resources in Xinjiang.
