The result showed that:(1) There were a higher density of Ostreidae and Balanidae and a lower biodiversity in the cay sampling section of Daxie Island.(2) No significant difference was found in the macrozoobenthos community among the tide plat sampling section in Daxie Island.(3) There was a lower macrozoobenthos species number, biodiversity, and a higher density of Sternaspis scutata and Capitella capitata than those in the sea area beside Daxie Island. Moreover, a significant difference was found in the macrozoobenthos community between the sea area of Daxie Island and the adjacent islands.
