太湖富营养化现状及其生态防治对策

The Current Eutrophication Status of Taihu Lake and Its Ecological Control Countermeasures

太湖是太湖流域的主要水体,由于流域内工业、农业的高速发展及生活污水无节制排放,水污染防治相对滞后,加之湖泊自身的水文特征等效应,使太湖富营养化形势严峻,并已危及流域内的经济发展和居民正常生活。太湖富营养化是典型的生态问题,因此可通过恢复湖泊水生植被,限制湖泊网围养殖面积,实施生物操纵控藻,建设环湖生态农业区,恢复湖滨带生态等生态防治对策加以控制。

As the high-speed development of industry and agriculture, non-controlled eduction of live sewage, relative lag of cure of water pollution and its own water character, the current eutrophication status of Taihu lake, the mostly component of Taihu valley, is dangerous and has endangered the economy development and people's natural life in the Taihu valley. The eutrophication of Taihu lake is a representative ecological problem, so it can be controlled by some ecological control countermeasures, such as resuming aquicolous vegetation, restricting the area of breed aquatics in the Taihu lake, biologically manipulating alga, building ecological agriculture section around the Taihu lake and resuming the zoology of Taihu bank .
