摘要

Among the Chinese lakes with the problem of eutrophication,the Taihu Lake,the Chaohu Lake and the Dianchi Lake have the worst cases of blue algae outbreak,which happen every year.Other lakes also have problems of blue algae outbreak at various degrees.However,some lakes dont have such problems.Practices have shown that through comprehensive management,the problem can be basically eliminated or significantly alleviated. " Water bloom" and blue algae outbreak have different connotation.The major factors affecting blue algae outbreak are sources of pollutants and ecological environment.Experiences are summed up and a new thinking on its management is developed:resolving the problem of blue algae is fundamental to lake management and development goals should be clearly set forth so as to eventually build a healthy aquatic ecosystem.The problem of blue algae cant be fully tackled by solely relying on the management of eutrophication but only by combining efforts of reducing the amount of blue algae and the management of eutrophication.The number of reduced blue algae should be larger than that of naturally proliferated algae so as to alleviate and eliminate the problem of blue algae outbreak.Various engineering and technical measures and relevant protective procedures should be carried out in a scientific and proper manner.The total amount of nitrogen and phosphorous entering the lake either from point-source or nonpoint source pollution should be substantially reduced.Controlling the source of pollution and intercepting pollutants are the basic measures.Wastewater treatment plant is the largest point source pollution in the future and adequate plants should be built with improved emission standards.Meanwhile,other measures including fishing out blue algae,diverting water,dredging,ecological restoration and expanding reed zone,should be implemented to alleviate the problem of eutrophication and eventually eliminate the problem of blue algae outbreak.
