%X Using ecological methods,we investigated the influence of reclamation on macrobenthic community in the terrestrial zone,the siltation zone and the nature tidal flat of the Hengsha East Shoal from April to December in 2011.The investigation showed that a total of 28 species were found.The rank of the number of macrobenthos species were the nature tidal flat(22 species) > the siltation zone(19 species) > the terrestrial zone(7 species).The rank of the dominant species were the nature tidal flat(6 species) > the siltation zone(5 species) > the terrestrial zone(2 species).The rank of the average abundance of macrobenthos were the siltation zone(118.68ind/m 2) > the terrestrial zone(100.67ind/m 2) > the nature tidal flat(57.67ind/m 2).The rank of the average biomass were the siltation zone(35.71g/m 2) > the nature tidal flat(27.56g/m 2) > the terrestrial zone(1.52g/m 2).The rank of the diversity indices(H’,J,d) of macrobenthos were the nature tidal flat > the siltation zone > the terrestrial zone.The results of CLUSTER and MDS showed that there were significant differences among the three different habitats.The ABC curves also indicated that the macrobenthic community of the siltation zone and the terrestrial zone had been changed while the nature tidal flat were relatively undisturbed.In conclusion,reclamation has significantly changed the composition of macrobenthos.
