摘要
在针对太湖五里湖水质严重污染和生态严重退化的情况,从分析浅水湖泊生态恢复的理论入手,提出生态恢复过程中控源减污、生境改善、生态重建、稳态调控的四个关键步骤,评价了西五里湖生态恢复示范工程的效果,计算了示范工程区水生植物覆盖度和生物多样性指数,指出达到景观要求的草型清水稳态湖泊还需要一个漫长的演替过程。
The Wulihu lake has been serious polluted and its ecology has been serious degenerated, it was suggested that the controlling the source to reduce pollution, improving the habitat , ecology reconstruction and the regulation of regime shift theory were the essential steps for the Wulihu lake restoration, depending on the shallow lakes restoration theories. This article also discussed the effect of the west Wulihu lake ecological restoration demonstration project and calculated the degree of acquatic plant coverage and the biodiversity index, then it suggested that would be a long-term to make the lake as a stable state of clear water.
