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 本論文用數(shù)理統(tǒng)計(jì)方法(包括:雙向指示種分析、多維定標(biāo)序列分析、判別分析和多元回歸分析)對(duì)春、秋兩季東、黃海浮游動(dòng)物群落進(jìn)行了劃分、確定各群落的指示種;對(duì)南黃海浮游動(dòng)物的種類組成、分布及其時(shí)空變化進(jìn)行了研究,并與歷史資料進(jìn)行了比較;并探討了黃海冷水團(tuán)對(duì)某些浮游動(dòng)物的意義,以及浮游動(dòng)物對(duì)黃海暖流指示。
