Abstract  Taking southeastern margin of Tengger Desert and Southwestern margin of Mu Us Sandland for example, the authors study the dynamic change of soil mechanical composition and soil nutrient of lands with different desertification degrees during the recovering process. Results show that: with the increase of vegetation coverage and recovery degree, the clay and silt contents in both desertified lands of different areas and different locations of the same area all increase clearly(P<0.05); the soil character develops toward loamification and fine graining, the content of organic matter, total nitrogen and total phosphor also increases clearly(P<0.05); The content of available nitrogen and available phosphor has a corresponding increase. There is a significantly positive relation between the content of soil organic matter, total nitrogen, total phosphor and the content of soil clay and silt, and there is also a significantly positive relation between the former threen. Meanwhile, the relationship of the content of soil clay and silt and that of the available nitrogen and available phosphor takes on a distinct variance with different locations and land utilization ways.
Key words:  soil recovery      soil mechanical composition      soil nutrient
