| Abstract: | Land use change may influence a variety of natural and ecological processes, including soil nutrient, soil moisture, soil
erosion, land productivity and biodiversity. In this paper, 9 typical land use patterns sustainable 15–20 years have been
chosen to study the effect of different land use patterns on soil nutrient, soil erosion, soil moisture, saline and so on.
We drew conclusions as follows: Firstly, it is clear of the effect of land use change on soil. Land use change results in
the decline of soil nutrient and erosion rate, but the increase of land productivity; secondly, the erosion rate and the rate
of vegetation cover is the subtractive correlativity. It reflects the effect of soil erosion on land productivity. It is clear
of the positive correlativity between land productivity and soil moisture and explains the role of land surface vegetation
to preventing aridity in the northwestern China; lastly, it is feasible to develop animal husbandry properly in arid region.
The topgallant land use pattern is the combination of forest and meadow in arid region. The rational land use may prevent
or weaken the intensity of soil erosion in a certain extent. Therefore, activities accorded with ecological principal such
as readjustment of land use structure, rational reclamation along with adoption of prevention and control measures can reverse
land degradation process.
