摘　　要：湖泊富营养化将直接导致水质下降,功能减退,水生态系统失衡;富营养的治理至今尚无一个湖泊实现水质和生态的完全恢复,即富营养化是一个不可逆过程。本文在分析了湖泊富营养化的现状、成因和危害的基础上,提出了湖泊富营养化的治理对策:严格控制外源污染,逐步去除内源污染,通过物理、化学和生物抑藻技术辅助抑藻;利用生物、生态方法,依靠水生态系统的自然规律,结合人工强化措施进行湖泊富营养化的生态修复。同时指出,采取污染源控制和生态修复是最根本、有效的治理方法,符合可持续发展的要求,也将是今后富营养化治理的发展方向。The eutrophication in lakes will directly lead to water quality deterioration and functional decline as well as aquatic ecosystem unbalance.The eutrophication is an irreversible process so that there is not a lake restoration original water quality and ecological condition through the eutrophication pollution control.Based on the analysis of present situation,causes and harmfulness of the lake eutrophication,the control measures were put forward： strict control of the exogenous pollution and remove gradually the endogenous pollution as well as inhibitting algae by physical,chemical and biological technology.The ecological restoration of eutrophication in lakes should combine biological and ecological technology with artificial strengthened measures,depend on the natural regulation of the aquatic ecosystem.The paper also points out that the pollution source control and ecological restoration are the most effective and ultimate treatment methods complying with the requirement of sustainable development and will be the developing direction of eutrophication control in future.
