典型风蚀区地表土壤抗风蚀效应测试研究

he test was carried out on different land surface in half-arid and inclined-arid region in Yinshan Mountain Area. On the basis of the test’s result and sand sample’s calibration coefficient, We calculated several land surfaces’ erosion rate and anti-erosion efficiency. and amount of wind erosion. The result shows that the erosion rate of degenerated grassland and traditional tillage farmland are much more than that of non-degenerated grassland and conservation tillage farmland when wind velocity is constant. Non-degenerated grassland and conservation tillage farmland have much better anti-wind erosion capabilities. Their wind erosion rate vary gently with wind velocity changing and there is not critical point of wind erosion rate. They have obvious anti-wind erosion capabilities to 8 level wind or so.
