Title: Storage and distribution of mountain soil organic carbon in west Yunnan
Abstract: The research on medium and small-scale soil organic carbon storage was the basis of improving the accuracy of large-scale study.The soil organic carbon storage in Dali Autonomous Prefecture was estimated and analyzed,according to the physiochemical property and distribution area of 158 typical soil profiles from the second soil survey of Yunnan Province.The result showed that the average soil organic carbon density in Dali Autonomous Prefecture was about 17.88 kg·m-2,which was higher than the national level.The total amount of soil organic carbon storage was about 470.68×106 t.The soil organic carbon density and storage were variation among different soil types.The soil organic carbon density varied from 6.32 to 51.85 kg·m-2.Meanwhile,soil organic carbon storage ranged from 0.06×106 to 137.36×106 t.The distribution of soil organic carbon density and storage were both higher in northwest and lower in southeast in general.
