英文摘要：

There are a lot of factors that influence water environment evaluation. Their reciprocal effects are very complex. In order to clearly reflect different factors in water environment evaluation, the fuzzy comprehensive evaluation method is used in this paper to deal with water environment. Research results show that the fuzzy comprehensive method has good dependability for water environment evaluation. It can calculate main pollutants, provide data for reasonable water environment management and play a reference role in other methods used in water environment evaluation.
