【摘要】 分析了1997年7月台湾岛东部和南部浮游动物的种类组成、群落结构和数量分布的特征,并探讨和研究它们与环流的相关性.共记录浮游动物421种,可分为4个生态类群:广高温高盐类群、狭高温高盐类群、广温广盐类群和高温低盐类群.种类和个体数均以广高温高盐类群占优势,表现出热带大洋群落的特征. 着重分析浮游动物的分布与水系的关系,如浮游动物密集区的形成及不同生态类群的分布与黑潮水、低盐水和副热带逆流的相关性;巴士海峡多种不同性质水系共同影响对浮游动物产生的效应.此外,还从种类的多样化、生物量的分布等方面与1997年冬季浮游动物的分布进行了比较.更多还原

【Abstract】 The characteristics on species composition,population structure and mumber distribution of zooplankton in the subtropical circulation system in July 1997 are analysed,and the relation between the characteristics and circulation currents is also studied and discussed. Altogether 421 species of zooplankton are recorded and they belong to respectively the four ecological groups:eury-hypertherm and hyperhaline group, steno-hypertherm and hyperhaline group, eurytherm and euryhaline group, and hypertherm and hypohaline group.Of them the eury-hypertherm and hyperhaline group plays an absolute dominant position,which exhibits the characteristics of tropic pelagic community. The distribution of total biomass of zooplankton in the survey area is analyzed. It also emphatically analyzes the interrelationships between the distribution of zooplankton with the circulation such as the distribution in zooplanktonic concentrated area with Kuroshio, hypohaline water with subtropic countercurrent, and the effects on zooplankton brought by the hydrometric structure of the common influence of multiple water systems in the Bashi Channel,. In addition, the variety of species and biomass distribution are compared with those of zooplankton in the winter of 1997.更多还原
