摘 要: | 衡水湖是位于河北省东部平原的一个人工湖泊,水源供给主要靠外流域调水.水体相对静止,水量交替缓慢,来水量水质复杂多变,对湖水水质影响较大.为净化水质,衡水湖采用以水生植物进行水质净化的措施,取得了良好的效果.通过对来水量水质、湖水水质监测,分析水生植物对氮、磷物质的净化作用;在不同水生植物区进行取样分析,采用综合污染指数对比的方法,分析不同水生植物的净化作用和效果;分析结果表明:水质净化效果最好的是沉水植物区,依次分别为荷花区、蒲草区、芦苇区.水生植物在净化水质的同时,也美化了环境.

Abstract: | Hengshui Lake is one of the artificial lakes in the eastern plain of Hebei Province.Its water supply mainly depends on water diversion from outside basin.Water body is relatively static,quantity of water alternates slowly,and water quality is complex and changeable,which have great effects on the water quality of the lake.Aquatic plants are used to purify the lake and good results are achieved.By monitoring water quantity and quality,purifying effect of aquatic plants to nitrogen,phosphorus materials is ana... |
