分析2007年4月在青岛近海进行的大型底栖动物定量采集样品资料,研究了该海域大型底栖动物群落的优势种组成和物种多样性、生物量、丰度和群落等级聚类分析(CLUSTER)以及群落受污染扰动情况.本次调查中共获得青岛近海大型底栖动物89种,其中多毛类41种,甲壳动物32种,软体动物5种,棘皮动物6种,其它类群动物5种.群落中优势种以日本美人虾(Callianassa japonica)和日本倍棘蛇尾(Amphioplus japonicus)贡献率较高.平均生物量和丰度空间分布高值区均出现在近岸海域.群落结构聚类分析表明,15个取样站的群落结构相似性程度都非常低,为10%～30%,仅有S10站和S13站、S3站和S9站Bray-Curtis相似性系数达到40%.ABC曲线表明,S6,S7,S12,S13站的底栖动物群落已受到中度扰动,其它各站ABC曲线状态正常,表明底栖动物群落基本未受干扰,处于较稳定状态.

The macrobenthic samples were collected in the coastal Waters of Qingdao in the survey in April. 2007. The characteristics of the macrbenthic population are analyzed to study the dominant species,biomass,abundance,and the species diversity,and to conduct the CLUSTER analysis for the population classification and to learn the pollutional impacts on the population. 89 species are found in the area,including 41 species of Polychaeta,32 of Crostacea,5 of Mollusca,6 of Echinodermata and 5 of the others. The dominant species are Callianassa japonica and Amphioplus japonicus. High values of the average biomass and the abundance are located in the near-shore region. It is learnt from the CLUSTER analysis that the values of Bray-Curtis similarity in the macrobenthic community structure are very low at the 15 stations,ranging from 10% to 30%. The values are above 4% at the S10,S13,S3 and S9 stations. The macrobenthic communities are impacted by the pollutions at the S6,S7,S12,and S13 stations,as the ABC curves show. They are normal without any pollution impact at the other stations.
