| Abstract: | Grassland is the one of the most important terrestrial ecosystem and plays an important role in the carbon budget. The driving factors of degraded grassland and carbon changes were discussed. The key driving factors and dynamics of carbon of degraded grassland were discussed. The carbon sequestration potential and mechanism of grassland ecosystems were discussed based on grass and soil properties. And some suggestions were given for researching on the carbon dynamics of grassland ecosystems. |
