In order to study the effects of granulated straw (JG) and fungus residue (JZ) amendments (6,12,18,24 t/hm²,respectively) on soil carbon pool of alpine sandy land in northwest Sichuan,a field location experiment was conducted. The results showed that the application of JG and JZ amendments could significantly improve the organic carbon,organic carbon storage,activated carbon,soil microbial biomass carbon,microbial entropy and carbon pool management index of desertification soil,and the enhancement effect on soil microbial biomass carbon and microbial entropy was the most significant. Compared with CK,the soil organic carbon,organic carbon storage,active organic carbon,and carbon storage management index of JG increased by 96.2%,100.0%,157.1%,169.4% on average,while those of JZ treatment increased by 69.2%,66.3%,85.7% and 81.7% in the second year after application amendments. Compared with CK,the microbial biomass carbon and microbial entropy of JG increased by 934.0%,433.0% respectively,while the microbial biomass carbon and microbial entropy of JZ increased by 956.2% and 546.4% on average. JG amendment had a better effect on the improvement of soil organic carbon storage components and carbon pool management index than JZ,while JZ amendment was beneficial to the improvement of soil microbial biomass carbon content and soil organic carbon turnover rate. Both granulated straw and fungus residues could increase the component content of soil organic carbon pool and improved the turnover rate of soil organic carbon and carbon pool management index,which also could fertilize the sandy soil rapidly.
