摘    要:自2004年8月~2005年4月对青岛岩相潮间带的2个断面(二浴东和小青岛)逐月进行了大型底栖动物群落生态调查,共采集到了9门74种大型底栖动物。初步分析结果显示,2个断面的生物量接近,分别为3498.80和3512.00g·m^-2(湿重),但栖息密度有明显差别,分别为2620.44和1552ind·m^-2中潮带的生物量和平均栖息密度远大于低潮带;贻贝(Mytilus edulis)作为绝对优势种主导着2个断面生物量和栖息密度的分布特征。此次调查的2个断面的多样性指数均不高,小青岛的多样性指数和均匀度高于二浴东。

关 键 词:大型底栖动物  岩相潮间带  生物多样性  青岛

Abstract:Survey of macrobenthic fauna at the 2 sections in the rocky intertidal zones of Qingdao ( the east of the second bathing beach section and the small Qingdao island section) was carried out monthly from August, 2004 to May, 2005. Seventy-four species of nine phyla were collected. The biomass of the two sections were 3 498.80 and 3512. 00 g·m^- 2 (wet weight), respectively, and the density of the two sections were 2 620. 44 and 1 552 ind·m^-2, respectively, Mytiluz edulis dominated the biomass and density of the macrobenthic fauna on the two sections. The biomass and density of the mid intertidal zone were greater than those of the low zone. The average Shannon-Wiener indices and Pielou's evenness index of the two sections in this study were not high, but the indices of the small Qingdao island section were higher than those of the east of the second bathing beach section.
Keywords:macrobenthic fauna  rocky intertidal zone  biodiversity  Qingdao
