摘　　要：根据1995-1997年期间在台湾岛以东副热带环流区进行4个季度月的综合调查资料，分析了该海域浮游桡足类的数量分布及其群落的生态特征，探讨其与环境因素的相关性．结果表明，本区大中型浮游桡足类呈低丰度（4个季度平均为6．75个／m^3）、低优势度（Y〈0．131）以及季节变化幅度小等特点．所记录的206种浮游桡足类中，5种生态类群共存．不同性质水系在测区间的动态制约着不同生态类群的配比，但丝毫左右不了热带大洋广布类群的主导地位．The abundance distribution and ecological characteristics of planktonic copepods are analyzed. Their relations to the environmental factors are discussed based on data obtained from 4 cruises during a multidisciplinary survey in the waters under the subtropical circulation zone east of Taiwan Island from 1995 to 1997. The results show that the macro--medium planktonic copepods in this region is the characteristics of low abundance （four seasons average 6.75 个/m^3） , low dominance （Y〈0. 131） and low seasonal variations. A total of 206 copepod species recorded coexisted respectively to 5 ecotypes. It is suggested that these ecotypes were dynamically governed by different water masses nevertheless,the tropical oceanic group was consistently dominated.
