| 中文摘要: |
| 为了研究水生植物对污染水体的净化效果，以金边石菖蒲（Ａｃｏｒｕｓｔａｔａｒｉｎｏｗｉｉ）、香菇草（Ｈｙｄｒｏｃｏｔｙｌｅｖｕｌｇａｒ ｉｓ）、穗状狐尾藻（Ｍｙｒｔｏｐｈｌｌｕｍｓｐｉｃａｔｕｍ）、金鱼藻（Ｃｅｒａｔｏｐｈｙｌｌｕｍｄｅｍｅｒｓｕｍ）、眼子菜（Ｐｏｔａｍｏｇｅｔｏｎｄｉｓｔｉｎｃｔｕｓ）共５种水生植物为研究对象，在人工气候室中，利用水培法研究了其对污染水体的净化效果。试验结果表明，水生植物对污染水体具有很好的净化效果，可以作为净水植物；其中，金边石菖蒲和香菇草的去氮效果较好，金鱼藻、穗状狐尾藻和香菇草对磷的去除效果非常好；经过７周的试验后，金边石菖蒲、香菇草、穗状狐尾藻、金鱼藻和眼子菜对总氮的去除率分别为８６.２２％、９１.１３％、７９．６９％、
８３.１７％和６５．５１％；对总磷的去除率分别为８７.９４％、９２.０９％、
９２.6１％、９５．２０％和８５．８７％；水生植物对污染水体磷的去除效果比氮好，速度也比较快，可以把这几种水生植物作为人工湿地的首选植物，本研究能为人工湿地植物选择和降低污染水体营养盐水平提供科学依据。 |

| In order to study aquatic plants on the effects of polluted water purification，five kinds of aquatic plants as an object for study，including Acorns tatarinowii , Hydrocotyle vulgaris , Myrtophllum spicatum , Ceratophyllum demersum and Potamogeton distinctus were used by water culture method in the artificial climate chamber to study its purification effect. The experimental results show that: the experimental aquatic plants have a good cleaning effect on the polluted water，it can be used as water purification plants , which Acorns tatarinowii and Hydrocotyle vulgaris had a better effect on removing nitrogen，Ceratophyllum demersum、llyrtophllum spicatum and Hydrocotyle vulgaris had a good removal on phosphorus; after seven weeks growing the five the aquatic plants Acorns tatarinowii, Hydrocotyle vulgaris、Myrtophllum spicatum , Ceratophyllum demersum and Potamogeton distinctus for total nitrogen (TN) removal were 86.22% , 91.13% , 79.69% ,83.17 % and 65.51% respectively，for total phosphorus(TP ) removal were 87.94 % , 92. 09 % , 92. 61%, 95.20 % and 85.87 % apart; the removal of phosphorus in the polluted water was better than nitrogen，so the speed. Therefore，it can put these aquatic plants as the preferred plant on the constructed wetland，which supported scientific basis for selection the constructed wetland plants and decrease the level of nutrition in the sewage water.
