摘　　要：本文根据模糊数学方法和地面水环境质量标准建立了地面水水质综合评判模型，并给出了十种污染因素隶属函数表达式．通过对渭河五个段面水体样本的综合评判，说明了模糊综合评价方法及本文建立的隶属函数的合理性和可靠性，它们对于环境管理具有实际意义。By use of the fuzzy method and based on the Environ-mental Quality Standard of suface water (GB3838-88), an overall guantitative method on evaluating surface water guaity and membership functions of ten pollution factors are stressed An example coprehensively overall evaluating water guality of Wei River with five samples by using this method is given.It is shown that the stressed approach and membership function were rational reliable and have practicability in environmental management.
