灰色聚类法在汇河水质评价中的应用

Application of the Gray Clustering Method on Water Quality Evaluation of Huihe River

以位于山东省肥城市境内的汇河为研究对象,对该河流4个监测断面(北军寨桥、衡鱼南桥、衡鱼北桥和陈屯桥)2008年3,5,7,8,10,11月的水质运用灰色聚类法进行了综合评价.评价结果表明,汇河的总体水质不佳,北军寨桥和衡鱼南桥污染严重,两个断面的评价结果均为Ⅴ类水;衡鱼北桥的水质较好,优于其他三个断面.评价结果为污染控制提供了科学依据.

The water quality of Huihe River in Feicheng city of Shandong provience was studied in this paper.Comprehensive evaluation of four monitoring cross sections（Beijunzhai Bridge,South Hengyu Bridge,North Hengyu Bridge,Chentun Bridge） and nine pollution factors using the water monitoring data of March,May,July,August,October and November in 2008 was conducted by Gray Clustering Method evaluation model.The evaluation results showed that the water qualities of Beijunzhai Bridge and South Hengyu Bridge were both Grade Ⅴ and worst among the four monitoring cross sections.Relatively,the water quality of North Hengyu Bridge was better than the other three.Overall,the pollution of Huihe River was serious.The evaluation results supported scientific basis for controlling water pollution.
