摘　　要：根据2003年1—12月在胶州湾所获得的浮游动物样品,鉴定出浮游动物71种,幼虫、幼体34类。分析了该海域浮游动物的分布﹑时空变化及其与生态环境因子的关系,同相关历史资料进行了比较,结果表明,浮游动物的种类多样性符合中纬度海湾水域浮游动物分布的一般规律,生态属性以暖温带、近岸低盐种类为主。浮游动物生物量和丰度的分布具明显的季节性变化,生物量平均为84.28mg/m3,饵料生物丰度平均为531.76个/m3,非饵料生物为72.08个/m3。浮游动物生物量和饵料生物丰度的分布季节变化与海水平均温度的季节变化节律基本一致,相关回归分析亦证实与温度的关系更为密切。浮游动物生物量的时空分布﹑种类多样性的变化趋势,近20a来基本相同,高峰出现时间的差异,主要是受温度年季和季节变化差异因素的影响。Based on the planktons sampled in the Jiaozhou Bay during the time period from January to De-cember 2003,totally 71species of zooplankton and 34groups of plankton larvae are identified.The spatial-temporal distribution and variation of the species,and their relationships to the environmental factors of the sea area are analyzed.As it is shown by the results from the analysis and the comparison with the his-torical data,the zooplankton species diversity is in accordance with the general rule of the zooplankton dis-tribution in the mid-latitude bay waters.The ecological attributes is mainly of the in-shore and low-salt species of the warm temperate zone.Zooplankton biomass and abundance vary from season to season.The annual mean biomass is 84.28mg/m3,the mean nutrimental zooplankton abundance is 531.76ind/m3,and the counterpart of non-nutrimental zooplankton 72.08ind/m3.The seasonal variation of the zooplankton biomass and the nutrimental zoolankton abundance accords with that of the water temperature.It is evi-denced from the regression analysis for the correlative factors that they can be more closely related to the temperature variation.The temporal-spatial distribution of zooplankton and the species diversity do not va-ry much and maintain a similar variation in the recent 20years.Although there is temporal difference a-mong the annual peak times of the biomass and abundance,it can be attributed to the temperature abnor-mality in the inter-annual variation and the seasonal variation.
