| 摘 要： | 针对湖泊富营养化问题,结合抚仙湖当前污染状况,以马料河人工湿地为例,探讨利用人工湿地控制水体水质下降、脱氮除磷机理及其去除效率.结果显示：马料河人工湿地对TN、TP、SS的去除效率分别为：44.21%、46.03%、86.6%;其中TN的去除效率与进水流速具有一定的相关性;TP的去除效率相对稳定,去除机制主要与湿地基质有关.

| Abstract: | Taking constructed wetland of Maliaohe River as an example, this paper discussed the control of lake eutraphication and removal mechanism and efficiency of nitrogen and phosphorus. Results demonstrated that the removal rates of TN, TP and SS were 44.21% , 46.03% and 86.6% respectively, and the removal rate of TN had a certain correlation with inlet velocity and that of TP depended on the substrates of wetland. |
