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.展开更多
