摘　　要：通过对不同水体蓝藻水华大量观测比较分析,认为水体富营养化只是蓝藻水华发生的物质基础,但不存在必然的因果关系。该研究基于有关藻类吸收利用水中营养元素方面的知识,结合一些学者观测资料、研究结论或模拟实验等例证资料,进行科学论证,得出上水层营养缺乏引起的藻类种间的竞争是蓝藻启动悬浮机制的直接诱因,上表水层营养限制是导致蓝藻水华暴发的根本原因。This paper compares and analyzes the cyanobacteria blooms in different water bodies,and argues that the eutrophication is only the material basis of cyanobacteria blooms without necessary causal relationship.The research is based on the knowledge about algae absorption and utilization of nutrients in water,combined with the cross-validation of some scholars’observational data,research conclusions,or simulation experiments to conduct scientific verification.The competition between algae species caused by nutrient deficiencies in the upper water is a direct cause for cyanobacteria to initiate suspension mechanism.Therefore,it is argued that the nutrient limitation of the upper water layer is the primary cause of the outbreak of cyanobacteria blooms.
