摘　　要：研究浙江大、小长涂岛潮间带大型底栖动物的种类组成、数量分布和多样性指数等群落结构特征。共采获大型底栖动物标本34种,其中包括软体动物21种,节肢动物10种,脊索动物2种,腔肠动物1种。该潮间带大型底栖动物总平均生物量为842.68 g·m–2,总平均栖息密度为1186 ind·m–2。在各类群底栖动物中,平均生物量及密度都以软体动物居首位。大、小长涂岛潮间带大型底栖动物的多样性指数、丰富度指数和均匀度指数的分布范围分别在0.900—1.861、0.433—2.053和0.531—0.956,平均值分别为1.405±0.414、1.208±0.663和0.678±0.191。估算得出,大型底栖动物次级生产力的值为108.98 g·m–2。The community structure of the intertidal macrobcnthic fauna in major and small Changtu island of Zhoushan, Zhejiang, such as species composition, quantity distribution and diversity index, was studied in this paper. The results indicated that there were 34 species, including 1 species of Coelentcrata, 2 species of Chordata, 10 species of Arthropoda and 21 species of Mollusca. The average biomass and density in all stations were 842.68 g.m-2 and 1186 ind.m-2, respectively. The mollusca were the first in biomass and density among all macrobenthic fauna. The values of Shannon-Wiener index, Margalcfs species richness index and Pielou＇s evenness index were 1.176-2.115, 0.833-1.897 and 0.565-0.801; their averages were 1.405±0.414, 1.208±0.663 and 0.678±0.191, respectively. The secondary productivity of the intertidal marcobenthic fauna was 108.98 g.m^-2 based on Bery empirical equation.
