| Outline of Final Research Achievements |
Grassland ecosystem has been destroyed in Inner Mongolia, China, by the anthropogenic activities in recent hundred years, and desertification progresses rapidly. The results of this study indicated that grassland degradation caused by the over grazing become sever in order of Tongliao > Chifeng > Xilingol > Hulunbuir. Compared to exclosure (control) plots, the above ground biomass and soil microbial activity decreased and the physico-chemical properties of the soils deteriorated significantly in grazing plots. Carbon budget of the soils showed distinct different patterns. Soils in exclosure, mowing and small number tourist plots stored carbon, but carbon was released from soil in the plot with plenty tourists. However carbon store and release was in balance state in the grazing plot. The grassland soil was shown to lose carbon storage function by excessive sightseeing and grazing activity.
