摘　　要：于2009年5月对辽东湾西部海域进行了4条断面12个站位的大型底栖动物调查。调查海域共出现大型底栖动物78种,其中多毛类37种、甲壳类24种、软体动物13种、棘皮动物2种和其他类2种(分别是腔肠动物、纽形动物)。调查海域大型底栖动物总平均丰度为1675.8ind./m2,总平均生物量为21.366g/m2。该海域大型底栖动物群落按40%相似性程度可划分为4个。调查海域大型底栖动物群落整体正常,个别站位群落受到轻度扰动。Macrobenthos was investigated at 12 stations in the western waters of Liaodong Bay in May 2009. A total of 78 macrobenthic species were identified in the survey area in which 37 species were Polychaeta, 24 were Crustacea, 13 were Mollusca, 2 were Echinodermata, and the rest 2 species were other taxonomical groups. The average abundance and biomass were estimated to be 1675.8 ind./m2 and 21. 366 g/m2respectively. Four macrobenthic community groups could be identified at the 40% similarity levels according to CLUSTER. The macrobenthic community structures were slightly disturbed in two stations.
