In this paper,soil respiration rates were measured before and after the removal of soil bio-crust, which was formed during the desertification reversion process,with LiCor 6 400 gas exchange analyzer with soil respiration chamber attachment.

By applying the theory of dissipative structure, this paper researches the temporal series and the spatial structure of the reversion process of desertification, and discusses the fluctuations, formation of the dissipative structure, and unbalanced phase change in the reversion process of desertification.

The temporal-spatial dynamics of soil organic carbon of arable layer in reversed desertification area;

This article pointed out that the distributing pattern of Chinese desert and desertification is V shapesd, and the Qinghai-Tibet plateau uplift may be the main factor to this pattern.

Problems and suggestions in research on aeolian desertification in Tibetan Plateau

The results from remote sensor monitoring and field survey show that aeolian desertification process in the study area can be distributed into two stages: the developing stage from late 1980s to 2000,and the reversing stage form 2000 to 2006.

The aeolian desertification is a land degradation characterized by wind erosion mainly resulted from the excessive human activities in arid, semiarid and part of sub-humid regions in Northern Chian.
