为了解凡纳滨对虾（Litopenaeus vannamei）池塘水体中浮游植物群落的组成及变化,本文对凡纳滨对虾养殖水体中浮游植物进行了分析.结果表明,养殖水体中的藻类共由21个种类组成,属于5大门类.浮游植物优势种群分别为绿藻门的小球藻（Chlorella sp）和波吉卵囊藻（Oocystis borgei）,硅藻门的小环藻（Cyclostella sp.）、新月拟菱形藻（N.closterium sp.）、角毛藻（C.mueeleri sp.）,蓝藻门的平裂藻（Merismopediasp.）和席藻（Phormidium sp.）.在养殖早期和后期,浮游植物数量的变动范围分别为：0.5～2×107个/升和0.3～5×107个/升.

Phytoplankton community were analysed for the composition and variation of phytoplankton commu- nity of culturing pond of Litopenaeus vannamei in this paper. The results indicated that there were 21 species, be- longing to 5 Phylums in culturing pond. Dominant species of phytoplankton were Chlorella sp ,Oocystis, belonging to Chlorophyta and Cyclostella sp. ,N. closterium sp. ,C. mueeleri sp. , belonging to Bacillariophyta and Phormidium sp. ,Merismopedia sp. , belonging to Cyanophyta. In initial and final stage of culturing, the amount of phyto- plankton was 0.5 -2 × 107individuals/litre and 0.3 -5 × 107indiveduals/litre respectively.
