研究了后期凡纳滨对虾设施养殖29个池塘中浮游生物的种类组成、数量差异及种类多样性。结果表明：共鉴定出浮游植物5门25属40种，浮游动物3门14属17种，未鉴定种类8种。其中硅藻门27种，绿藻门7种，蓝藻门4种，黄藻门1种，甲藻门1种；原生动物门8种，轮虫类6种，枝角类3种。29个池塘浮游植物丰度6.3×102~4.4×104 cell/mL，生物量12.6~882.0 mg/L，Shannon-Wiener多样性指数0~3.17，Margalef丰富度指数范围0.56~0.95，Pielou均匀度0.19~0.90；浮游动物丰度12.6 mg/L~882.0 mg/mL，生物量1.2×102~2.7×102 mg/L。凡纳滨对虾养殖池塘中，浮游生物种类相对自然海区少、密度大。在相同管理模式下，池塘中浮游生物种类和数量有较大差异，多样性指数也有较大差异。

The species, quantity changes and biodiversity on the culture pond of Litopenaeus vannamei were studied . The results showed that the total number of species of phytoplankton were 40, out of which the Bacillariophyta takes up 27 species;the Chlo-rophyta had 7 species;and the Cyanophyta had 4 species;the Xanthophyta had one specie and Pyrrophyta had one specie. The total number of species of zooplankton were 17, out of which the Protozoa had 8 species;the Rotifers had 6 species;the Cladocerans had 3 species. The population density of phytoplankton was 4.4×104-6.3×102 mg/mL, the biomass was 12.6-882.0 mg/L, the Shannon-Wie-ner index was 0-3.17, the Margalef richness index was 0.56-0.95, the Pielou evenness index was 0.19-0.90. The population density of zooplankton was 12.6mg/L-1~882.0 mg/mL, method the biomass was 1.2×102-2.7×102 mg/L.The species number and the density were little than those in the sea. In the same cultivation, there are big different in the species and density of plankton.
