摘要
20世纪90年代至21世纪初,由于大规模发展围网水产养殖和围垦建鱼池,导致植被覆盖率的减少和污染负荷的增加,使东太湖水质变差。在实施退渔(鱼池、围网)还湖、疏浚行洪供水通道及污染底泥、修复生物系统等综合措施后,取得改善水质、提高植被覆盖率、预防蓝藻爆发等良好效果,使东太湖湿地生态系统基本进入良性循环。大中型浅水湖泊(湖湾)湿地修复、控制污染的关键是:修复以芦苇为主湿地、控制人工水产养殖污染、调水、清淤,充分利用有利的自然地理条件等。这些启示对太湖的其他水域,以及全国类似湖泊的湿地保护和修复有良好借鉴作用。
The water quality of East Taihu has become poor because of large-scale purse seine aquiculture, reclamation for building fishponds, reduction of vegetation coverage and increase of pollution load from 1990 s to early 21 st century. After comprehensive measures of returning fishing(fish pond, purse seine) to lake, dredging flood water channel & sediment pollution, and repairing bioremediation system, several great effects are achieved including improving the water quality & the vegetation coverage rate and preventing outbreak of blue-green algae, and the East Taihu Lake wetland ecological system has entered into a virtuous circle. The keys of large & medium-sized shallow lake(lake bay) wetland restoration and controlling pollution are repairing the wetlands with reed-dominated, controlling the artificial aquaculture pollution, water diversion, dredging and making full use of the favorable natural & geographical conditions, etc. These revelations can provide great references for conservation and restoration of Taihu's other water areas as well as the wetlands of domestic similar lakes.
