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.
