The more serious the eutrophication becomes, the more outbreak of the cyanobacterial blooms, it is necessary to pay more attention to prevention, removal and application of cyanobacteria. The harm of cyanobacteria and controllability was clear on the basis of the analysis of the cause of the attribute of cyanobacteria. The prevention and treatment of cyanobacteria were analyzed comprehensively and the all of advantages and disadvantages of the effects of various single treatment methods were reviewed. The synthetical measure was considered effectively to prevent the outbreak of cyanobacteria. The utilization approaches and methods of cyanobacteria have been revealed effectively according to its biological characteristics.%水体富营养化的状况越来越严重,蓝藻水华的爆发次数也越来越多,蓝藻的防治、去除及应用受到重视。本文在分析蓝藻的属性的成因的基础上,明确蓝藻的危害及可控性,综合分析了蓝藻防治手段,考察了各种单一处理法的利弊,提出综合除藻措施是破解蓝藻爆发的有效手段;针对蓝藻的生物学特征,揭示了蓝藻的有效利用途径和方法。
