摘　　要：根据模糊数学的方法,将隶属函数和隶属度等概念引入丹河水环境评价中,用矩阵分析的方法建立模糊综合评价模式。建立评价因子的因子集、评价集、隶属函数和权重集等模糊集合,对丹河进行了分类和质量标准的划分,根据各污染因子对水质的影响差异确定其权重,对丹河流域水环境模糊综合评价,采用了最大隶属度原则和加权平均原则相结合。结果表明评价结果与实际情况有较好的吻合。Using the basic theory and method of fuzzy mathematics, the membership function and relative membership degree of alternative were bought into the water environment evaluation, and then fuzzy comprehensive evaluation was constructed with matrix analysis means. According to the different water equality infection of various contamination factors, the objective weight was ensured. The evaluation factor sets, evaluation criteria sets, membership function and objective weight sets were established, and then a comprehensive fuzzy assessment for the present water environment of the Dan River valley was conducted, by using the principle of maximum membership function and the principle of weighted average method.
