荷兰浅水湖的生态恢复实践

湖泊的富营养化导致了湖泊生态系统的失衡。要使湖泊获得生态恢复,只通过控制入湖的营养负荷是不够的。荷兰的实践证明,外部营养负荷的大量减少并没有带来预期的恢复效果,而通过湖泊的换水和生物控制,湖泊的透明度、水生植物等得到了迅速改善。根据荷兰方面提供的资料,介绍了荷兰通过换水和生物控制进行浅水湖的生态恢复实践和取得的经验。

Practice on Ecological Restoration of Shallow Lakes in the Netherlands

The process of eutrophication of water body is very slow in nature. The human activities accelerate the processes mainly by eutrophication, which result in breaking the balance of the ecological system in lakes. It is not enough to restore ecological balance lakes just by controlling the entering loads of nutrition. The Netherlands' practice have demonstrated that reducing the external nutrition loading didn't attain the goals forecasted. The transparency and macrophyte improved much after flushing and biomanipulation. The paper introduced and described the practices and experiences of ecological restoration of shallow lakes in the Netherlands through flushing and biomanipulation based on the information supplied by the Netherlands partners.
