摘　　要：1997- 1999年连续 3年对太湖北部围隔实验区水生植被自然修复过程的观测表明 ,大型富营养化浅水湖泊滨岸水域 ,通过实施围隔保护等途径 ,土著水生高等植物如荇菜、菱等能够在次生裸区水域自然修复生长 .1998年夏季荇菜、菱种群覆盖面积分别达到围隔保护区总面积的 14.3%和 12 .7% .伴生种群有马来眼子菜、狐尾藻和苦草等 .分析了人为刈割、水产养殖对水生高等植物自然修复进程的影响 .It has been observed and studied that the natural restoration process of aquatic vegetation in the experimental enclosure of northern lakeside, Lake Taihu, from 1997 to 1999 years. It is found that the local macrophytes, for example, the Nymphoides peltata, Trapa sp. and Potamogeton malainus Mig, can be naturally restored in the bare lakeside of big shallow eutrophication lakes by an enclosed protection methods. The cover area by species of Nymphoides peltata and Trapa sp. has taken up to 14.3% and 12.7% of the total enclosure area in the summer of 1998, respectively. The companion species of vegetation are Potamogeton malainus Mig, Hydrilla verticillata Royle and Vallisneria spiralis L. The affection to the natural restore of macrophytes by anthropologic readping and fish culture has also been discussed. According to the results of enclosure experiment, it has provided a strategy for control of eutrophication in big shallow lakes, for example, Taihu Lake.
