　　于2010年6月至2011年1月对博斯腾湖大湖区浮游动物群落进行了4次调查研究。结果表明,共鉴出浮游动物83种(属),其中原生动物27种(属),轮虫42种(属),枝角类10种(属),桡足类4种(属)。浮游动物在种类上以淡水习见的广温性种类为主,兼有嗜暖种和嗜冷种；数量上小型浮游动物占优势(>64.8%)；生物量上大型浮游动物(主要是枝角类)占主导地位(>85.2%)。物种丰富度指数8月(夏季)最高(1.52),1月(冬季)最低(0.74)；物种多样性指数和物种均匀度指数10月(秋季)最高(3.01和0.95),1月最低(0.75和0.63)。群落多变量分析表明,博斯腾湖西北部(黄水区)和西南部浮游动物群落结构差异较大,从春季到秋季这种差异逐渐增大,冬季差异最小。本研究通过分析博斯腾湖浮游动物群落结构的种类组成、现存量、多样性指数和群落多变量探讨该湖浮游动物群落特征及其分布的季节性变化规律,以期为博斯腾湖水环境评价与保护、渔业资源合理利用和可持续发展提供理论依据。

We evaluated the community characteristics and distribution of zooplankton from June 2010 to January 2011 in Bosten Lake. We identified 83 species of zooplankton, including 27 species of protozoa, 42 species of rotifer, 10 species of cladocera, and 4 species of copepoda. The zooplankton assemblage consisted primarily of hackneyed eurythermal species with a few thermophil andcryophil species. Micro-zooplankton were the most ab-undant type (>64.8%), whereas macro-zooplankton (chiefly cladocera) dominated the total biomass (>85.2%). The species richness index was highest in summer (1.52) and lowest in winter (0.74). The species diversity index and species evenness index peaked in autumn (3.01 and 0.95, respectively) and were lowest in winter (0.75 and 0.63, respectively). Multi-variate analysis revealed that there were comparatively large differences in zooplankton community structure between the northwest and southwest regions of Bosten Lake. These differences increased between June and October but were lowest in January.
