摘　　要：为探明小麦岛邻近海域大型底栖动物生态特征,于2018年10月对小麦岛邻近海域大型底栖动物群落进行调查和分析,通过野外采样、室内生物鉴定和环境因子测定,对其多样性、群落结构、环境因子相关性和丰度—生物量比较曲线进行研究。调查结果显示,本次调查共鉴定出大型底栖动物80种,包括环节动物多毛类57种、节肢动物甲壳类15种、软体动物3种、棘皮动物2种、其他类群生物3种。总平均生物量为65.42 g/m^(2),甲壳类贡献率最高;总平均丰度为474个/m^(2),多毛类贡献率最高。聚类分析结果表明,在25%的相似性水平上,调查海域大型底栖动物可分为3个群落。Shannon-Wiener多样性指数和丰度—生物量比较曲线的结果表明,调查海域部分站位沉积环境存在轻度污染的可能。底质中粉砂含量是影响该海域大型底栖动物群落结构和多样性的主要环境因子。The present study aimed to reveal the status of macrofaunal community and diversity in the surrounding area of Mai Island in Qingdao.Samples were collected from 9 stations in October 2018.The biodiversity,macrobenthic community structure,and correlations between biotic and abiotic parameters were analyzed in this study.A total of 80 species of macrobenthic fauna were identified,including 57 species of annelids,15 species of crustaceans,3 species of mollusks,2 species of echinoderms and 3 species of other taxa.The mean total biomass was 65.42 g/m^(2),of which crustaceans contributed most;and the mean total abundance was 474 ind./m^(2),of which polychaetes contributed most.The result of CLUSTER analysis showed that,at the 25%similarity level,the 9 surveyed stations were divided into 3 groups.The Shannon-Wiener diversity index(H′)and abundance and biomass comparison(ABC)curve showed that the sediment environment from partial stations were slightly polluted,while the other stations were relatively clean.The key environmental parameters affecting the characteristics of macrobenthic community and biodiversity of macrofauna in this area were the content of silty sand.
