| 摘 要： | 秋末冬初在富营养化滆湖的围隔中引种沉水植物,分别构建5种植被区、菹草-伊乐藻区、菹草区、伊乐藻区,调查4种区域内植被恢复及对水质的净化效果。结果发现菹草-伊乐藻区不仅能在冬春季节保持对营养盐较高的去除效果,并能在冬季有效缓解苦草等植物死亡（5种植被区）给水质带来的不利影响;菹草-伊乐藻区对比湖面敞开区域内TP,TN,NH3-N,Chl.a的去除率可达62.9%,31.5%,53.9%,46.1%,对CODMn的去除率仅为9.7%;比较各单种区：伊乐藻对TN的去除效果要好于菹草,菹草对TP的去除效果要好于伊乐藻。

| Abstract: | From the late autumn to the early winter,submerged macrophytes were introduced to the enclosures in Eutrophic Gehu.Five macrophytes community,Potamageton crispus-Elodea nuttallii community,Potamageton crispus community and Elodea nuttallii community were constructed respectively.The restoration and purification of submerged macrophytes of four communities were investigated.The results show Potamageton crispus-Elodea nuttallii community not only remains effective on removal of the concentration of water nutr... |
