摘要	该文论述了春秋季黄东海大型底栖动物的生态学特点,并结合历史资料,对底栖动物的季节变化及年际变化作了初步探讨.论文所需资料由2000年10～11月与2001年3～4月在黄东海进行的春秋季调查获得,在121～127<'0>E.26～26<'0>N之间海域共设49个大型底栖动物取样站.除少数种类待鉴定外,两次调查共发现四大类群底栖动物543种,其中多毛类39科147种,软件动物56科182种,甲壳类41科144种,棘皮动物21科70种.该文对黄东海大型栖动物种类分布特点、生物量及栖息密度的分布与季节变化进行研究,并计算生物多样性指数,作生物多样性分析.
其他摘要	This paper presents the results of ecological study of the macrobenthic fauna in the Yellow Sea and the East China Sea. The materials for study were collected from 49 stations in the shelf area west of 127°E between 26°～36°N, in October-November 2000 and March-April 2001. A total of 543 species of macrobenthos were collected. The specie-number of Polychaeta is 147 species, Mollusca 182 species, Crustacea 144 species, and Echinodermata 70 species. The distribution of species of macrobenthos, their biomass and density, and biodiversity indices were described and discussed. Based upon the analysis of the data obtained during the survey, it can be concluded that: 1) The number of biomass of macrobenthos in the Yellow Sea and the East China Sea in autuma is higher than that in spring, while the number of density of macrobenthos in autumn is lower than that in spring; 2) The number of biomass of macrobenthos in the Yellow Sea is higher than that in the East China Sea; 3) The number of species in the Yellow Sea is lower than that in the East China Sea; 4) One of the characteristics of distribution of macrobenthos in the East China Sea is that the species richness increased from the coastal waters to the offshore deep waters, from the north to the south. 5) The species composition in the deeper part occupied by the cold water mass of the Yellow Sea is more stable than that in the coastal part of the Yellow Sea in the late 40～50 years.
