Characteristics of bacterial community structure at two sites in the Red Soil Critical Zone Observatory,China
The critical zone evolves from coupled biological,physical,and geochemical processes that we quantify here across varying climatic and topographic conditions.The specific objective of this work was to evaluate vertical distribution of soil bacteria with depth in soil profile on two sites at Sunjia Red Soil Critical Zone Observatory in China.The bacterial diversity was assessed by sequencing 16S rRNA gene amplicons with Illumina Miseq technology.Results showed that bacterial community similarity was different at low depths(0-30cm)as the different land use management in this two sites and Acidobacteria,Proteobacteria and Chloroflexi were dominant phylum in this two sites.Based on Canonical Correspondence Analysis,we found significant relationship between bacterial community and soil physicochemical properties.Soil moisture and nutrient factors like soil organic content contributed directly to the bacterial community structure and its diversity.In conclusion,our results suggest that bacterial display different spatial pattern and its regulated by different forces in the soil profile at Red Soil Critical Zone Observatory.
