| Abstract: |
| Aimed at the degraded grassland enclosed for different years, study w as made on the distribution of organic carbon wit hin degraded ecosystems. The results showed that: With the increase of enclosing years,
the density of soil organic carbon grows increasingly，while the highest value of plant organic carbon density oc-curs in the 20 years of enclosing, and the plant carbon intensity of enclosing for 25 years is slightly lower than that of enclosing for 20 years，show ing a low ering trend. Carbon density of processed ecosystem of enclosing for 25 years reaches the highest, 8.22 kg/m2; the proportion of carbon pool in soil in the total reserves of organic carbon pool in ecosystem is little influenced by the enclosing years. |
