胶州湾潮间带大型底栖动物的群落生态

潮间带是沿岸带位于最大高潮水面到最小低潮水面之间的区域,处于陆海过渡带,生物资源非常丰富,也是受各种理化环境因子以及人类活动影响最大的区域。我国近年来对各地不同类型的潮间带进行了一些生态调查研究,包括对胶州湾也进行了数次生态调查,如劭晓阳等(2001)研究了浙江省岛

Macrobenthic community of the intertidal zone of Jiaozhou Bay

Based on the macrobenthic samples collected seasonally from 9 intertidal stations in Nugukou (N1, N2, N3, the high, middle and low tidal stations), Hongshiya (H1, H2, H3, the high, middle and low tidal stations) and Xindao (X1, X2, X3, the high, middle and low tidal stations) around the Jiaozhou Bay during August 2003 to May 2004, the macrobenthic community of intertidal zone of the Jiaozhou Bay was analysized using PRIMER, of which CLUSTER, MDS and DIVERSE functions were adopted. The results revealed that 110 species were found in the three locations, including 38 species of mollusk, which was the most abundant, 36 species of polychate and 18 species of crustacean. The species compositions, dominant species and the three diversity indices among the 9 stations differed. The results of CLUSTER and MDS analysis showed that the macrobenthic communities from the 9 sampling stations could be converged to four groups, namely, A group, including Stations N1, N2, N3;B group, including Stations H2, H3;C group, including Stations X1, X2, X3, and D group, including only Station H1. The types of macrobenthic community correlated with the types of substratum.
