摘要
为进一步了解大冶湖的水质现状,运用水污染指数法(Water Pollution Index,WPI)评价了2020年大冶湖大桥、磊山湖心、大冶湖闸3个断面的水质。结果表明,磊山湖心WPI全年平均值最小,水质明显优于另2个断面。对比同一断面不同月份的WPI,大冶湖监测断面5—6月份的水质是一年当中最差的;2—3月份水质是一年当中最好的。这可能是5—6月份雨水充沛,将面源污染物冲刷至大冶湖中所致。
In order to research the water quality status of Daye Lake further,the water pollution index(WPI)was used to evaluate the water quality of three water quality monitoring sections of Daye Lake Bridge,the middle of Leishan Lake and Daye Lake Sluice in 2020.The results showed that the annual average of WPI in the middle of Leishan Lake was the lowest among the three sections,and the water quality of the middle of Leishan was obviously better than that of the other two sections.By comparing the WPI of the same section in different months,in the three monitoring sections of Daye Lake,the water quality in May and June was the worst in 2020,while it was the best in February and March.This may result from the abundant rainfall in May and June which washed non-point source pollutants into Daye Lake.
