摘　　要：2011年4月到2012年2月在南日岛东岱村大牛山和大峤山2个岩相潮间带断面进行底栖生物调查,共鉴定出南日岛东岱村岩相潮间带生物73种,其中软体动物49种,藻类8种,甲壳动物7种,棘皮动物6种,多毛类1种,其它动物2种。各季节潮间带生物平均生物量为1 658.01 g/m2,平均栖息密度为23 420 ind/m2。潮间带生物种类多样性指数范围为0.42～1.84,丰富度指数范围为0.67～1.71,均匀度指数范围为0.12～0.42,辛普森优势度指数0.13～0.61。结果表明,南日岛东岱村潮间带底栖生物的分布特征受到栖息环境、季节变化和人为活动的综合影响。A survey on two rocky intertidal sections in Dongdai Village of Nanri Island was carried out from A- pril 2011 to February 2012. 73 species were identified and analyzed, including 49 species of Mollusca , 8 species of Algae, 7 species of Crustacea, 6 species of Echinodemata, 1 species of Polychaeta, and 2 others. The average biomass of benthos in the intertidal zone was 1 658.01 g/m^2, and the average inhabit density was 23 420 ind/m^2. The biodiversity index varied 0.42 - 1.84 ; the index of Margalefs species richness varied 0. 67 - 1.71 ; the Pielou＇s evenness varied 0. 12 -0. 42; and the index of Simpson＇s dominance varied 0. 13 -0.61. The distribution characteristics was the result of multiple factors, including habitat, seasonality, and human activity and so on.
