Abstract: From November 2012 to October 2013, macrobenthic assemblages and biodiversities were investigated seasonally in different intertidal habitats of Maoyan Island in Taizhou, Zhejiang Province. The habitats included artificial Kandelia obovata mangrove forests with different ages, Spartina alterniflora marsh, and bare mudflat. A total of 48 species were recorded, belonging to 28 families, 9 classes, and 8 phyla. Arthropods, mollusks, and annelidas accounted for 83.3% of the total. The density characters of quantitative sampling were used to calculate Shannon index, Pielou index, Margalef index, Simpson index, and G-F diversity index. The results showed that the species and density in S. alterniflora habitat were lower than in K. obovata and natural tidal flat habitats. The numbers of species in summer and spring were higher than in autumn and winter. Either Shannon index or G-F index in mangrove forests was higher than in the other habitats. The species diversity in the young mangrove forest was lower than that in the 6 and 8-year-old mangrove forests, but family and genus diversities were higher in the young mangrove forest. Variance analysis and hierarchical cluster showed that habitat and season were the key factors affecting the distribution of macrobenthic communities.
