This paper briefly introduced the current situation of the study on the causes of the large- scale cyanobacteria blooms at home and abroad in the large shallow lakes, reviewed some common understandings about water-forming mechanism, analyzed the major environmental factors of solicitating blue-green algae water blooms in Chinas large shallow lakes, and then brought up some targeted control measures about blue-green algae outbreaks in lakes. Key words:shallow lake;eutrophication;cyanobacteria;mechanism;control measure 　　水体富营养化是目前世界各国所面临的重大环境问题之一.蓝藻水华的暴发是水体富营养化的一个 突出表现.大规模的蓝藻水华不仅会降低水资源的利用效能, 还会引起严重的生态破坏和巨大的经济损 失,而且蓝藻毒素的产生也极大地影响着公众的健康.引起蓝藻水华的种类主要有微囊藻(M icrocy stis )、
