From May 2006 to September 2008, the paper investigated the community composition of phytoplankton of the Heiyu Lake in Daqing. The results show that there is an increasing by 36 to 52 genuses from 2005. These 52 kinds of phytoplankton respectively belong to 6 phylums, 32 families, and 52 genuses. The firstly dominant phytoplankton namely Bacillariophyta was substituted with Chlorophyta, and the changes of water quality displayed a trend from eutrophication to heavy eutrophication. It was pre
