摘  要：
于2011年5月对乳山湾潮间带8条断面的大型底栖动物进行了定量调查,共鉴定出大型底栖动物116种,其中多毛类58种、软体动物15种、甲壳类27种、棘皮动物3种,其他动物13种.调查潮间带大型底栖动物的平均丰度为872.6 ind·m-2,平均生物量为9.37g·m-2,根据相对重要性指数(IRI)计算优势种为中蚓虫、沈氏厚蟹、纽虫和刺沙蚕等.丰富度指数(d)、多样性指数(H)和均匀度指数(J)平均值分别为2.119、2.384和0.608,为轻度污染海域.以30%的相似性尺度,可将所调查潮间带8个断面划分为3个群落.与同纬度海湾潮间带相比,乳山湾潮间带大型底栖动物具有种数多、个体小、丰度高的特点,仅从大型底栖动物群落结构和多样性指数方面不足以证实该海域贝类养殖对环境产生扰动并对底栖动物群落造成影响,还需要进行更深入的调查研究来综合判断.

摘  要：
Quantitative study on macrobenthos was carried out in 8 transects along intertidal zone of Rushan Bay in May,2011. In total,116 macrobenthic species were identified,among which 58 were polychaetes,15 were mollusks,27 were crustaceans,3 were echinoderms and 13 were other groups. The average abundance and biomass of macrobenthos were 872. 6 ind · m-2and 9. 37g·m-2,respectively. By IRI index,Mediomastus sp.,Helice sheni,Nemertinea and Neanthes sp.were ranked as the top 4 dominant species in the study area. Average Margalef's species richness diversity( d),Shannon diversity( H) and Pielou's evenness index( J) of macrobenthos were2.119,2.384 and 0.608,respectively,indicating slight pollution in the study area. Based on 30%similarity level,8 transects could be grouped into 3 different communities. Compared with other intertidal zones in similar latitude,macrobenthos of Rushan Bay intertidal zone were characterized by higher species number,smaller body size and higher abundance. Besides the macrobenthic community structure and diversities,more exhaustive studies were needed to reveal the possible influence of shellfish culture on intertidal macrobenthic community.
