Abstract:

In order to understand the characteristics of macrobenthic communities in the intertidal zone for mangroves, two sections of bare flat, two sections with a small number of Spartina alterniflora distribution and two sections covered by Spartina alterniflora were selected in Beihai for ecological investigation, and the community structure of macrobenthic animals and its relationship with environmental factors were analyzed. There were 29 macrobenthic species in the survey area, and there were significant differences in mollusc biomass, arthropod habitat density and crab burrow number in different habitats (P< 0.05), and the species composition of macrobenthic animals was positively correlated with sediment skewness (P< 0.05). The HJ community structure was stable in the bare flat, but the community structure of macrobenthic animals in the other plots was unstable. The growth of Spartina alterniflora affects the structure of macrobenthic communities.

Key words: macrobenthic animals, community structure, Spartina alterniflora, mangrove
