Abstract: We explored bacterial community structure and geographical distribution on the top layer sediments in five sites in the East China Sea by constructing 16 S r DNA clone library. The results show that the bacteria were belonged to 13 groups including Proteobacteria, Firmicutes, Acidobacteria, Chloroflexi, Actinobacteria, Nitrospira, WS3, Bacteroidetes, Spirochaetes, OP8, Planctomycetacia, Verrucomicrobiae, and Gemmatimonadetes. The Proteobacteria and Chloroflexi were the dominant groups of all sites. WS3, Verrucomicrobiae, and Gemmatimonadetes were unique to Sites DH6, DH9, and DH21, respectively. The descendent order of bacterial diversity in site is DH9 > DH21 > DH17 > DH6 > DH16. In addition, community structure and abundance were closely related to different types of local sedimentary environments.
