Grassland is an important ecosystem carbon pool in China. Several grassland ecological protection projects have been implemented to control grassland degradation and desertification in China. To reveal the impact of ecological management on ecosystem carbon sequestration, four future scenarios of grassland ecological management were set based on the current intensity of grassland ecological managements. Grassland soil carbon sequestration was estimated in China from 2001 to 2030 by using the IPCC Method for National Greenhouse Gas Inventories. The results showed that the mean grassland carbon sequestration was -0.54×108 t CO2 eq/a from 2001 to 2010 in China. The grassland soil carbon sequestration significantly increased to -1.00×108 t CO2 eq/a on average during 2011-2017. Under different grassland ecological management scenarios, the grassland soil carbon sequestration is -0.42×108 to -2.00×108 t CO2 eq/a in China. And grassland soil will sequestrate -5.46×108 to -26.01×108 t CO2 eq accumulatively from 2018 to 2030. This study provides reference for the formulation of future grassland ecological management policies.
