Abstract: The spatial distribution of macrozoobenthic community in five transects of the intertidal zone of Chongming East Shoal was investigated from April to December in 2012.A total number of 40 species was found.The average values of abundance and biomass were(210.30±93.56)ind/m2and(74.07±16.03)g/m2,respectively.Correspondingly,the average values of biodiversity indexes d,H′ and J were 1.81±0.41,2.55±0.38,0.67±0.11.Cluster and MDS analysis showed that there was a significant difference between the southern transects and the northern ones.Using similar historical data from2000 to 2006,the process of the long-term succession of macrozoobenthic community structure in Chongming East Shoal was also analyzed.This historical study indicated that the species number,abundance,and biomass in this area were decreasing.The average taxonomic distinctness( +)also displayed a decreasing trend,while the variation in taxonomic distinctness( +)had an increasing trend,suggesting a closer genetic relationship among species in community.Environmental change and anthropogenic disturbance may be the major causes for the simplification of community structure.
