英文摘要	Bacterial communities play a vital role in marine biogeochemical processes. Revealing the effects of geographical distance and environmental conditions on bacterial communities is important for better understanding how environmental changes can drive microbial diversity and maintain their functions. In this study, the diversity and spatial distribution of bacterial communities in water and surface sediments of northern South China Sea were analyzed through high-throughput sequencing of bacteria 16S rDNA, and the effects of environmental factors, geographical restrictions and seabed depth on microbial communities were examined. The results showed that about 95% of bacterial 16S rDNA sequences belonged to the dominant phyla/classes Gamma-proteobacteria, Firmicutes, Cyanobacteria, Alpha-proteobacteria, etc. The dominant bacterial groups in sedimentary samples were mainly related to the environmental parameters such as grain size and N, while the dominant bacterial groups of water samples were closely related to sampling depth. The results of correlation test showed that α-diversity indexes of sedimentary samples had significant correlations with C, while both α-diversity indexes and β-diversity distance matrix of water samples showed significant correlations with sampling depth. In addition, geographical distance and depth of the seabed were not detected to have a significant effect on β-diversity, which may be due to the insufficient space scale of sampling.
