摘　　要：利用高等植物风车草对水体中营养物质的吸收、吸附作用来修复富营养化的双龙湖。试验表明,通过在湖面种植4m宽的风车草带,可以在距其25m的范围内起到净化修复湖水的作用,且在影响半径范围内水质随着离风车草带距离的减小而逐渐好转。The higher plant Cyperus alternifolius.l was used for renovation of eutrophicated urban inner lake by, the action of Cyperus alternifolius.l adsorbing the nutrients. The experiment showed that a zone with width of 4m where this higher plant was planted could take a role in purification and renovation for lake water within 25m, and moreover, in the scope of 25m , water quality became good gradually with the range from this plant decreasing.
