The objective of this study was to investigate the vertical distribution of soil carbon and correlations of rubber trees of 1a、6a、11a,16a,21a,26a,31a-old of strain PR107. The results showed that in the vertical distribution,monthly mean soil organic carbon(SOC)and mineralized carbon(CM)and microbial biomass carbon(MBC)content in soil showed similar regularity and decreased with the increase of soil depth,but the carbon content in different soil layers,different ages have different performance.The soil mineralization carbon efficiency of rubber plantation is about 4.15%~8.39%;and the efficiency of soil microbial biomass carbon is between 1.24%~7.55%.There was a significant linear positive correlation with soil organic carbon and mineralized carbon and with the microbial biomass carbon.
