用隶属度法分析柳杨河水体污染状况

隶属度法和试行评价法对柳杨河两个断面及整个河段进行了分析和评价,结果表明,隶属度法不但可以确定某项污染物是污染等级,还能计算出超标倍数,对试行分析法进行了补充和订正,使得分析结果更加准确。同时分析了断面和水体污染原因,为环境管理提供技术支持和依据。

Analysis of Water Pollution in Liu Yang River with Membership Degree Method

We analyzed and evaluated water pollution of two cross sections and total river section of Liu Yang river with Membership degree method and trial evaluation method.We compared the results of the two methods and found that the membership degree method not only could determine a contaminant being what level of pollution,but also could calculate the degree exceeding this level quality standards.Membership degree can be used to supplement and revise trial analysis evaluation method,which makes the analysis results more accurate.In the mean time,it can analyse the pollution reason of water body,and provide technical support and basis for environmental management.
