根据twinspan等多元分析结果，比较各组群的浮游动物种类组成和环境特征，可将东、黄海浮游动物群落分为5个，黄海沿岸群落（ f ） ，指示种秋季为真刺唇角水蚤，春季为墨氏胸刺水蚤；黄海中部群落（ hc ） ，指示种以细长脚虫戎为主，秋季还有中华哲水蚤和太平洋磷虾；东海外陆架高温高盐群落（ k ） ，指示种为角锚哲水蚤、飞龙翼箭虫等多种狭布型暖水种类；黄东海交汇区群落（ he ）和东海近岸混合群落（ m ） ，两群落包含多种生态类型种类，其中温带近岸低盐种在he中较多，广布性暖水种在m群落中较多。 - In this paper , zooplankton communities , their species composition and indicator species in the east china sea and the yellow sea were examined with multivariate methods . in the southern part of the yellow sea , where was known as an important spawning ground of anchovy , the seasonal variations of zooplankton were studied in details with respect to species composition , abundance , biomass and vertical distribution . furthermore zooplankton indication of the yellow sea warm current ( yswc ) in winter was discussed
本论文用数理统计方法（包括：双向指示种分析、多维定标序列分析、判别分析和多元回归分析）对春、秋两季东、黄海浮游动物群落进行了划分、确定各群落的指示种；对南黄海浮游动物的种类组成、分布及其时空变化进行了研究，并与历史资料进行了比较；并探讨了黄海冷水团对某些浮游动物的意义，以及浮游动物对黄海暖流指示。
