河流水环境质量评价分析

摘要

随着社会经济的快速发展，水环境出现了严重污染问题。运用模糊综合评价法从水体水质方面对桑干河水环境质量进行评价，建立适合于桑干河的模糊综合评价模型，根据污染物对水质的影响程度大小来确定权重，在评价中利用复合运算对桑干河4个监测断面的水质评价结果进行分析，得出东榆林水库属Ⅱ类水质和固定桥、堡子湾和艾庄均属Ⅴ类水质的结论。%With the rapid development of social economy,the serious pollution of water environment is a worldwide prob⁃lem needed to resolve. Sanggan River’s water environment quality is evaluated with the method of fuzzy comprehensive evaluation. The suitable fuzzy comprehensive evaluation model of Sanggan River has been build. The weight has been deter⁃mined according to the size of influence of pollutants on water quality. The water quality evaluation is analyzed of Sanggan River’s four monitoring sections through compound calculation. The results show that:Dongyulin Reservoir is II class wa⁃ter,Gudingqiao,Baoziwan and Aizhuang Reservoirs are V class water.
