Abstract

In this paper,taking 33 years old low-efficiency Cupressus funebris plantation for an object,researches were conducted on the short-term effect of 15% (T1),25% (T2),35% (T3,) and 50% (T4) thinning on the changes and correlation of its soil organic carbon and active carbon. This low-efficiency Cupressus funebris plantation is located in Jingyang District of Deyang City,Sichuan Province. The results indicated that after one year,the total organic carbon(TOC),microbial biomass carbon(MBC),readily oxidizable carbon(ROC),and water-soluble organic carbon(WSOC) increased with the strengthening of thinning intensity,while the positive effects of T3 and T4 were significant at the level of 0.05. Furthermore,there existed significant positive correlations among the TOC and ROC,WSOC and SMBC. Thus,the results displayed that the thinning could facilitate Cupressus funebris to sequestrate more carbon in the soil of the low-efficiency plantation within hilly regions of Sichuan.
