    Abstract
  • The purpose of this study is to reveal the effect of microbe on the cycle of soil organic carbon (SOC) in karst areas. Soil samples of paddy fields，maize fields and citrus orchards were collected from a karst area, mixed area and non-karst area at the Maocun karst experimental site in Guilin. The abundance, composition and diversity of microbe were compared based the results from high-throughput sequencing technology. The results show that there are 48,159 sequences with 2,602 OTUs. The dominant phylum of soil bacteria (relative abundance >10%) are Proteobacteria, Acidobacteria and Actinobacteria. The dominant classes (relative abundance >10%) are Acidobacteria and β-proteobateria. The OTUs abundances of both Proteobacteria and Latescibacteria subgroup 6 in the karst area are higher than those in the other two areas. The relative abundances of both subgroup1 and subgroup 2 in the karst area are lower than those in the other areas. Redundancy analysis indicates that SOC, pH and total nitrogen are the key factors to cause microbial changes.
