Phytoplankton communities at the water depth of 0.5,5,and 10 m were investigated in the lacustrine zone of Dashahe Reservoir in the winter from December,2009 to February,2010.Total precipitation in the three months was 263 mm;temperature ranged from 15.5℃to 19.4℃;the water column was fully mixed.Sixty four species of phytoplankton belonging to six phyla were identified. Total phytoplankton abundance ranged from 4.1×106 to 14.8×106 cells·L-1.There was no significant difference in the dominant phytoplankton species at the three water layers.Anabaena circinalis and Microcystis aeruginosa were the predominant species,and contributed to about 70%of total abundance in all of the sampling periods at all depths.Anabaena and Microcystis blooms slightly occurred in the December of 2009 and February of 2010.The regulating buoyancy of cyanobacteria,as well as low availability of phosphorus and light led to the dominance of the two species.
