摘　　要：引种了能越冬的浮床植物黄菖蒲、西伯利亚鸢尾,采用维纶醛化丝制作平行排列式人工水草,与美人蕉进行水质改善比较研究,对SRP,TP,NH4^＋-N,TN的去除率分别为70.39%-99.22%,62.07%-94.98%,58.03%-99.26%,59.67%-91.06%。其中,黄菖蒲去除效果突出,对4种污染指标的去除速率分别达到98.42,88.98,1118.87和1668.06mg/（m^2·d）,其次为美人蕉、西伯利亚鸢尾,人工水草最弱。黄菖蒲对4种污染指标的去除速率分别是美人蕉去除速率的2.93,2.82,3.63和5.31倍。黄菖蒲和西伯利亚鸢尾耐寒能力强,能越冬,管理工作量小,且西伯利亚鸢尾在冬季有较好的景观效果。推荐黄菖蒲和西伯利亚鸢尾作为城市水体生物浮床水质改善的主要植物。In this experiment,Yellow Calamus,Siberian Iris,Canna indica and artificial plant were used to remove SRP,TP,NH4＋-N and TN of micro-polluted source water,and the removal rate was 70.39% - 99.22%,62.07% - 94.98%,58.03%- 99.26%,59.67% - 91.06%,respectively.Among them,Yellow Calamus had the greatest capacities to remove SRP,TP,NH4＋-N and TN,the removal rates were 98.42,88.98,1 118.87 and 1 668.06 mg/（m^2·d）,respectively.Canna indica followed,Siberian Iris was the third,artificial plant was the worst.The removal rate of four polluants by Yellow Calamus is 2.93,2.82,3.63 and 5.31 times that by Canna indica.Both Yellow Calamus and Siberian Iris had strong ability to against the cold in winter,and the workload of management was not arduous,what＇s more,Siberian Iris produced better landscape effect in winter.So Yellow Calamus and Siberian Iris were recommended as the main plants of ecological floating bed technology on urban water quality improvement.
