石岛海域大型底栖生物群落特征

2008年8月~2009年5月分4个航次对石岛海域进行大型底栖生物调查，共发现大型底栖生物164种，整个调查海域内大型底栖生物的优势种明显；调查海域大型底栖生物平均密度和平均生物量分别为279个/m2和11.00 g/m2；调查海域大型底栖生物初步分为近岸的粗砂底质群落和离岸较远的泥沙底质群落。本调查结果与其他海域调查资料做了对比，并初步分析了与其他调查海域结果不同的原因。

Characters of marine macrobenthic community in Shidao area, Shandong Peninsula

Based on the material collected during August 2008 to May 2009 in the Shidao area, eastern end of the Shandong Peninsula, the species compostion, distribution and community structure of marine macrobenthos were studied and reported in the present paper. In total, 164 macrobenthic species were found from the research area, and the dominant species were obvious. The mean density and biomass were 279 ind./m² and 11.00 g/m² respectively. The macrobenthic community of the research area can be classified as two kinds of type: the seashore rough sandy community and the offshore mud sandy community. These results from the research area were compared with those from the adjacent areas, and the differences among them were discussed.
