巢湖生态系统的变化和修复措施
|
摘要
巢湖水域面积减小,大量湿地萎缩,水位高度由自然节律变为人工控制的常年高水位,巢湖水体自然净化能力大幅降低。水土流失和点、面源污染严重造成巢湖底泥、湖水严重富营养化,浮水植物藻类化,鱼类趋向小型化。研究结果表明,巢湖生态系统正经历巨大变化。提出了内、外源性营养物质的控制等生态修复措施恢复巢湖生态平衡。
There are so many changes such as the reduced water area,a large amount of shrinking wetlands,a perennial water level controlled by the law of natural into artificial high water level and the sharply reduced water self-purification capacity of Chaohu Lake. The soil and water loss,the serious sediment caused by point and non-point source pollution,the serious eutrophication of Chaohu Lake,the floating algae,increasing miniaturized fish all show that the ecological system of the lake is undergoing great changes. Taking all the problems into consideration,it was proposed that the internal and external source of nutrients should be limited in Chaohu Lake to restore the ecological balance.
