摘　　要：在人工浮岛上栽种20余种本土水生植物,通过试验,考察这些植物的生存能力、去污效果、管理难易等诸多方面因素,对这些植物进行综合指标评分,最终筛选出最优的水生植物组成浮岛系统,动态观察其去污效果。室内试验结果表明,植物的生长状况良好,其叶长、株高、根长均有显著增长,对污染水体中的COD的去除率可达90%以上,TN的去除率可达60%以上,TP的去除率可达70%以上。并且,从中筛选出的植物,可以作为人工浮岛生态系统选种植物,从而扩大了可选植物品种范围,所组成的浮岛系统不仅适用于面源性水污染的治理,还可与其它工艺组合用于点源性水污染的治理。Transplanting over twenty species of plants from the countryside to the artificial floating rafts,the growth,purification effects and management of these plants were investigated. To score these plants by comprehensive index,the best to make up the artificial floating rafts was sected. Then the purification effects of the plant system was observed. In lab test,the plant growth was well and the removing rates of COD,TN and TP were 90%,60% and 70%,respectively. At the same time,the plants selected in the test could increase the plants＇ options of the artificial floating rafts. The plant system not only could be used in non- point source pollution contral,but also could be used in point source pollution contral by combining with other technology.
