摘　　要：于2011年1月至2011年10月,每季度一次对红枫湖水库浮游植物及环境因子进行采样调查,结果显示:红枫湖水库中假鱼腥藻(Pseudanabaen limnetica lauterborn)细胞密度全年保持在107cells/L以上,占浮游植物总丰度的72%～80%,在浮游植物群落中占有最主要的优势,这是2011年红枫湖水库浮游植物群落结构的最显著特征。调查研究后发现,2011年红枫湖水库的水温(WT),pH,溶解氧(DO)等环境因子与浮游植物的丰度显著相关,但对浮游植物群落结构的影响较小。Phytoplankton and environment factors in Hongfeng Lake Reservoir were investigated quarterly from January 2011 to October 2011. Results revealed that Pseudanabaen limnetica lauterborn, maintaining in the 107cells/L above in this whole time with 72% - 80% total abundance of Phyto- plankton being occupied, was uppermost dominated in the phytoplankton community of Hongfeng Lake Reservoir, which is the most remarkable characteristic of Hongfeng Lake Reservoir phytoplankton com- munity structure in 2011. After investigating and studying, it showed that the environmental factors of water temperature （WT）, pH, Dissolved Oxygen （DO） and so on was significant related to the phyto- plankton abundance, but less affecting the structure of phytoplankton community.
