摘　　要：文章选择风车草、彩叶草和茉莉等观赏性植物对富营养化鱼塘水进行漂浮种植试验,观察植物的生长适应情况,评价供试植物对水样中COD、N、P等污染物的净化效果。结果表明,风车草和彩叶草可以正常生长,但茉莉的生长适应能力较差;3种植物对富营养化水样均有较好的净化效果,其中风车草效果最佳。Cyperus ahemifolius, coleus blumei and jasmiunm sambac were cultured in a floating bed for the treatment of eutrophicated water, and changes in the concentrations of COD, N, and P in the tested water samples have been measured. The cyperus ahernifolius and coleus blumei grew wel/in the eutrophicated water, however, the growth of jasmiunm sambac was restrained. The results show that floating culture of all the plants tested can improve the treatment of eutrophicated water, especially in the case of cyperus ahemifolius.
