摘　　要：在模糊物元分析原理的基础上,结合水质评价的特点和海明贴近度的概念,提出了基于模糊物元分析方法水质评价模型.在对水质进行综合评价时,分别把水质的分类等级和水样作为物元的事物,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,通过计算与理想模糊物元之间的海明贴近度,实现对水样水质的等级评价和水样排序.研究结果说明:该模糊物元模型简便、通用,计算结果较为客观和稳定,为水质综合评价提供了新的有效方法.In order to evaluate the water quality, a new method is put forward on the basis of the fuzzy matter-element analysis and combining with the concept of Simdilar approach degree,and the feature of evaluation of water quality. Regarding the levels of water quality and water samples as the objects of matter-element,and the compound fuzzy matter-element are constructed with the evaluation factors and their fuzzy value of the object, through calculating Simdilar approach degree between the fuzzy matter-element and the standard （the best） fuzzy matter-element, the level of water quality and the sequences of water samples are achieved. The effect of application show that the model which provides a new effective method to evaluate the water quality is convenient, current and the outcomes are object, stable.
