【摘要】 利用中日黑潮联合调查研究期间1986年5～6月航次水文与生物的同步取样资料,通过水系与浮游动物桡足类、水母类和浮游植物甲藻类的对应分析,给出了在正常大气系统下、物理海洋学中水系分析结果与海洋生物学中的水系指示生物对东海水系及其混合变性程度的指示作用,二者耦合程度较好;进一步证明了海洋生物的生存与海洋环境有着密切的关系,海洋环境的变化直接影响到生物生态类型的分布及其数量的改变。很多生物类群可作为环境因子特别是水团的良好指示种,其数量的改变可作为判断不同水系混合变性程度的个重要根据。对海洋生态环境问题的合理解释离不开水系与流系的正确判断和分析。更多还原

【Abstract】 The hydrographical and biological data on samples synchronously collected from May to June 1986 in China-Japan joint research program on the Kuroshio are used in this paper. Corresponding analysis between water type and zooplankton (pelagic copepods, siphonophore) photoplankton (Dinoflagellates) is made, and the result indicates their corresponding relation is good. It further proves that there is close relation between the marine organism subsistence and the environment. The environmental variation has a direct influence on ecotype distribution and its quantity change. Many ecospecies can be used as indicator of water type. Change of the quantity can be used to judge the extent of water type mixing and modification. And reasonable explanation of oceanic ecological environment needs correct analysis of water type and current.更多还原
