On the basis of field investigation and information research in Shenmu County, according to the fundamentals of air flow pressure field theory, the specific wind erosion laws are analysed and soil coarsening causes are discussed. The results are as follows. ① soil wind erosion occurred on facing the wind slope, top of hilly and airflow converging landforms places; ② soil windsand accumulation occurred on the lee slope and airflow divergence landforms places; ③ soil coarsening resulted form winderosion o...
