摘    要:本文根据1982年8、11月,1983年2、5月调查资料对长江口、杭州湾浮游动物的生态类型、数量分布、种类多样性等进行了阐述和分析,并对其与环境污染的关系进行了探讨。研究结果表明本调查区浮游动物其生态类型基本以半咸水性河口种类、低盐度近岸种类及温带外海种类为主;在调查区内从种类组成和标本形态来看,虽然目前不能断言污染物对浮游动物的影响,但生物量却有明显下降,浮游甲壳类中铜、锌积累较严重,调查期间出现二次赤潮,范围为30多平方公里和10平方公里左右。这些现象应引起重视。

关 键 词:浮游动物  生态类型  低盐度  温带  生物量  生态调查  种类多样性  种类组成  甲壳类  数量分布

Abstract:The ecological pattern, distribution and diversity of species ofzooplankton in Changjiang Estuary and Hangzhou Bay were investigated and analyzed.On this basis, the impact of pollution on the zooplankton was discussed. It was discoveredthat the hemi-saline estuarine species, low salinity neretic species and temperate offshorespecies were dominating zooplanktons in the investigated areas. In accordance with thecomposition and morphology of the zooplanktons, it is still uncertain whether or notthe extent of the pollutants affected the species. However, the biomass of zooplanktonconsiderably decreased and a large amount of copper and zinc was accumlated in theplanktonic crustacean. Moreover, there occurred two times of red tide which wererespectively more than 30km~2 and 10 km~2 during the period of investigation. There-fore we should pay more attention to all these phenomena.
Keywords:ecology of zooplankton  Changjiang estuary and Hongzhou Bay  biomass  pollutants affected the zooplanktons
