基于灰色关联分析法在区域水环境评价中的应用--以锦江河流域为例

摘要

According to the data from four water monitoring stations at Meihewan, Shimawan, Tanwan and Jinbin, the water environment at the downstream basin of Jin River was evaluated through grey reIational analysis in this study. The resuIts showed that the water environment was severeIy contaminated by phosphorus, am-monia nitrogen and permanganate.%根据锦江河流域下游湄河湾、石马湾、谭湾、锦滨等4个监测点的水质监测结果，运用灰色关联分析法评价该流域下游水环境。结果表明：该域水环境受到较严重污染，主要污染因子为总磷、氨氮和高锰酸盐指数。
