[Objective] To calculate the carbon content of the main forest stands in the abandoned land in Jinchuan mine of Gansu Province, and estimate carbon storage years of vegetation in restored areas to provide scientific basis for incorporating ecological restoration system into the voluntary reduction of greenhouse gases in China.[Methods] The organic carbon content of the main species in the restoration area was determined by dry burning method. The average carbon content, vegetation carbon storage density and carbon storage of the main species in the restoration area were estimated and their characteristics were analyzed.[Results] In the repair area, the carbon content of the trees was 0.462 9~0.403 8. The carbon content of the shrubs ranged from 0.413 9 to 0.453. The average carbon content of 8 herbaceous plants was 0.144 5, which was ranked as follows:trees > shrubs > herbs. The average carbon storage density of vegetation in the ecological restoration area of Jinchuan mine abandoned land was 6.209 2 t/hm², and the total carbon storage was 635.10 t. Among the total carbon storage allocation, the arbor was the highest, accounting for 86.71%, and the shrub was the second, accounting for 12.65%. Plants accounted for a small proportion of total carbon stocks.[Conclusion] The ecological restoration of mine wasteland can increase the capacity of carbon storage in the mine area, and there is a great potential for the mine wasteland to be included into China's voluntary greenhouse gas emission reduction.
