摘　　要：2011年9月在湖北省对养殖水体桥墩湖的浮游藻类进行了调查,共鉴定出浮游藻类5门40属43种.浮游藻类的平均细胞数量为1.02×108个/L,平均生物量为14.56 mg/L.浮游动物29种,平均数量和生物量分别为13 189.62个/L、15.71 mg/L.其中中华小尖头藻(Raphidiopsis sinensia)、假鱼腥藻(Pseudanabaena sp.)和中华平裂藻(Merismopedia sinica)占到了总的浮游藻类细胞密度的80%.从生物量来说,优势种为硅藻门的尖针杆藻(Synedra acus),达到了总生物量的15.64%,以及浮游动物的轮虫为74.64%.In September 2011, an investigation of phytoplankton in the aquaculture Qiaodun lake was made. The identification result showed that there are 43 species, include varieties, belonging to 40 generas and 5 divisions. The average abundance and biomass of phytoplankton was 1.02 ×10^8 ind/L and 3.32 mg/L respectively. Zooplankton had 29 species, the mean density was 13 189.62 ind/L and biomass was 15.71 mg/L. Raphidiopsis sinensia, Pseudanabaena sp. and Merismopedia sinica contributed over 80% of the total phytoplankton cell dengsity. But from the biarnass the predominant species were the Synedra acus in Bacillariophyta and the rotifer in zooplankton, about 15.64% and 74.64% of total biomass,respectively.
