摘　　要： 鱼类清除和沉水植被恢复常是富营养化浅水湖泊生态系统修复的重要手段。为探讨这种生态系统修复方式对亚热带富营养化浅水湖泊太湖五里湖水质的改善效果,论文研究了五里湖生态修复区与未进行任何修复的对照湖区为期6个月(2010年7～12月)的水质监测数据。数据分析结果表明,生态修复区总氮(TN)、总磷(TP)、叶绿素-a(Chl-a)以及悬浮质(TSS)浓度显著降低,分别比对照区低43.4%、48.3%、65.5%和78.9%,透明度则明显升高,约为对照区的3倍。本研究表明以鱼类清除和沉水植被恢复为主要手段的生态系统修复措施能够有效改善亚热带富营养化浅水湖泊水体的水质。 The combination offish removal and macrophyte reestablishment is an important way to restore the eutrophic shallow lakes. In order to investigate the effect of this kind of restoration methodson water quality of the subtropical, eutrophic shallow Lake Wuli, Lake Taihu. The water quality of the restored and the un-restored area was monitored from July to December, 2010. The results showed that the concentration ofTN, TP, Chl a and TSS in the restored area were 43.4%, 48.3%, 65.5% and 78.9% lower than the un-restored area, respectively. The transparency in the restored area was about three times higher than that of the unrestored area （P〈0.05）. Based on these results, we conclude that the combination of fish removal and macrophyte reestablishment is an efficient method for restoring subtropical shallow eutrophic lakes, such as lake Wuli.
