摘　　要：为调查太湖湖滨带大型底栖动物群落现状和探索不同湖区之间差异,于2009年12月和2010年4月对太湖湖滨带49个采样点完成两次调查采样。共采集大型底栖动物3门7纲69种。太湖不同湖区的湖滨带之间分类数、平均密度和生物量都存在显著的空间差异(P<0.05)。经过计算可以得出,各湖区大型底栖动物多样性和均匀度从高到低依次为东部沿岸、贡湖湾、东太湖、南部沿岸、梅梁湾、竺山湾、西部沿岸。不同湖滨带生态环境的差异,影响了大型底栖动物群落结构的组成。In order to study macrobenthic community status and explore the differences between different districts in aquatic - terreestrial eeotones of Taihu Lake, two surveys were conducted with 49 sampling sites in December 2009 and April 2010.3 Phy- lum, 7 classes, 69 species were collected, species number average density and biomass are significant different in different lake districts（P 〈0. 05）. Diversity and evenness of the benthic fauna in descending order are eastern coast, Gonghu, East Taihu, southern coast, Meiliang Bay, Zhushan Bay, and western coast. The ecological environment differences affected the composition of macrobenthic community status.
