【摘要】 采用样方调查法对芝罘岛、养马岛和龙须岛岩岸潮间带的无脊椎动物群落进行了系统的生态学研究，样方面积为 40 cm×40 cm。3 个群落以养马岛的种类最多 (11 种)，芝罘岛和龙须岛均为 7 种，3 个岛屿的潮间带群落仅有 4 个物种为共有种，在种类组成上存在较大的差异。东方小藤壶在 3 个岛屿的岩岸潮间带群落中为绝对优势种，短滨螺、牡蛎、笠贝和黑荞麦蛤在群落中分别具有很高的优势地位。群落的多样性指数以养马岛最高 (R = 0.91, H’ = 0.67, E = 0.34 )，芝罘岛最低 ( R = 1.23, H’ = 1.20, E = 0.50 )，龙须岛居中 ( R =1.07, H’ = 1.12, E = 0.58 )。更多还原

【Abstract】 Quadrat method is used to investigate the invertebrate communities of rocky intertidal zone. Quadrat size is set at 40 cm×40 cm. The compositions of the 3 investigated communities are quite different. Chthamalus challengeri is the most dominant species in all communities of 3 investigated islands. Littorina brevioula, Ostrea spp., Patelloida spp. and Vignadula atrata occupy relatively higher dominance in the community respectively. The community diversity index ranks as follows: Yangma Dao > Longxu Dao > Zhifu Dao.更多还原
