To elucidate the relationship between phytoplankton structure indicators in littoral zone of Meiliang Bay,Taihu Lake.Weekly results showed that Cyanophyta,Chlorophyta and Bacillariophyta were three dominant groups,constituting 60%,16% and 22% of annual average total phytoplankton biomass, respectively.Chlorophyta and Bacillariophyta were the main dominant species in winter and spring,while in summer Cyanophyta was the only dominant species.From April to June,average water temperature(WT)was under 20℃,the biomass of Chlorophyta and Bacillariophyta decreased,and Cyanophyta biomass was low,with the total biomass lower than 1 mg·L-1.As WT increased above 25℃, Cyanophyta proliferated rapidly and became the only dominant species.Under the condition of enough nutrients and suitable meteorological factors,succession of phytoplankton structure contributed significantly to algae blooms.
