摘　　要：依据"我国近海海洋综合调查与评价专项"中北黄海海区大型底栖生物春季航次的采泥调查资料,对北黄海大型底栖生物群落进行了研究,共划分出3个底栖生物群落。其中群落Ⅰ位于山东半岛近岸以及辽东半岛长山群岛以北。种类组成以广温低盐种为主,不倒翁虫Sternaspis scutata、双唇索沙蚕Lumbrinreis cruzensis等为优势种。群落Ⅱ位于中央冷水团区,种类组成多为冷水性种,优势种为薄索足蛤Thyasira(Thyasira)tokunagai、浅水萨氏真蛇尾Ophiura sarsivadicola等。群落Ⅲ位于北黄海东部砂底区,种类少,蚕光稚虫Spiophanes bombyx、心形海胆Echinocardium cordatum等为优势种。与1958年的全国海洋综合调查等历史资料对比发现,沿岸性群落的优势类群发生了变化,多毛类动物取代了棘皮动物;冷水性群落的范围大约缩减了1个经度。The community structure of macrobenthos in the North Yellow Sea is presented in this paper.The study materials were collected from 80 stations located in 37°～40°N and 121°～124°E from Apr.24th to May.5th,2007.The macrobenthos were grouped into three communities.CommunityⅠwas located in the offshore areas of the Shangdong and Liaodong peninsulas,with eurythermal and low salinity species the dominant ones,such as Lumbrinreis cruzensis and Sternaspis scutata.Community Ⅱ,which was located in the Cold Water Mass area,contained mainly cold-water species,such as Thyasira(Thyasira) tokunagai and Ophiura sarsi.Community Ⅲ located in the easten part of North Yellow Sea,sand substrate,where Spiophanes bombyx and Echinocardium cordatum were dominant species.Compared with historical data,the dominant species in the offshore area were polychaetes instead of echinoderms,and the range of cold-water commnnity diminished by about one longitude.
