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

Among populations, Tringa totanus, Charadrius dubius, Charadrius leschenaultii, Egratta garzetta and Hirundo rustica were more common than other species. The structure of bird communities in each sampling area was analyzed, and the similarity between communities was studied by using cluster analysis method. The results demonstrated that the avian communities in Xiamen intertidal zone might be classified into three types and the community similarity was related to the intertidal base. Also, the influential factors of community diversity and the economic significance of the birds in Xiamen intertidal zone were discussed.展开更多
