摘　　要：在环境调查和监测的基础上综合评价了青龙河支流和部分青龙河段的水质现状,为青龙河的污染治理及规划提供了科学依据。在评价过程中,叙述了评价因子的选取、权重值的运算,并对其评价的结果与水环境调查的实际状况进行了对比分析。评价结论表明:模糊数学评价的结果与河流水现状相符;金矿排水对地面水有了不良影响,青龙河的水质已经有了变化,水质级别降低;评价方法有实用价值。The water quality of the Qinglong anabranch and the part of the Qinglong River is evaluated comprehensively based on the environmental investigation and monitoring, so as to provide the scientific basis for the pollution treatment and programming of the Qinglong River. This paper discusses the choice of the evaluated factors , the operations of the weight value, and compares with the status of the water environmental investigate in the course of the evaluation. The conclusions indicated the result of the fuzzy mathematics evaluation accorded with the water quality of this river. The mined drainage leads to the bad effects on the surface water. The water quality of the Qinglong River has already changed, and the water quality lever has reduced. So this evaluation is very important in application.
