摘　　要：通过2021年4—9月对衡水湖浮游藻类进行逐月的采样调查,共鉴定浮游藻类54属,主要是由绿藻门(29.63%)、硅藻门(29.63%)和蓝藻门(27.78%)等组成。分析衡水湖浮游藻类藻密度的动态变化和浮游藻类群落结构的变化,并对衡水湖蓝藻水华发生的可能性提出预警性分析,从而对水体富营养化防治和湖泊的生态修复等提供科学依据。Through the monthly sampling survey of phytoplankton in Hengshui Lake from April to September 2021,54 genera of phytoplankton were identified,mainly composed of Chlorophyta(29.63%),diatom(29.63%)and Cyanophyta(27.78%).Based on the analysis of the dynamic changes of phytoplankton density and phytoplankton community structure in Hengshui Lake,the possibility of cyanobacteria bloom in Hengshui Lake was analyzed in order to provide scientific basis for water eutrophication prevention and ecological restoration of the lake.
