英文摘要	Soil organic carbon (SOC) is very important in the vulnerable ecological environment of the Third Pole; however, data regarding the spatial distribution of SOC are still scarce and uncertain. Based on multiple environmental variables and soil profile data from 458 pits (depth of 0-1 m) and 114 cores (depth of 0-3 m), this study uses a machine-learning approach to evaluate the SOC storage and spatial distribution at a depth interval of 0-3m in the frozen ground area of the Third Pole region. Our results showed that SOC stocks (SOCSs) exhibited a decreasing spatial pattern from the southeast towards the northwest. The estimated SOC storage in the upper 3m of the soil profile was 46.18 Pg for an area of 3.27 x 10(6) km(2), which included 21.69 and 24.49 Pg for areas of permafrost and seasonally frozen ground`, respectively. Our results provide information on the storage and patterns of SOCSs at a 1 km resolution for areas of frozen ground in the Third Pole region, thus providing a scientific basis for future studies pertaining to Earth system models.
