Object: study the characteristic of the soil wind erosion of northwest China,make clear the potential dust source of northwest China,provide the theoretical support for the duststrom administration measures.

Being very little research on the common dust source control,this paper proposes the most important question that clarifies the dust production mechanism to control the dust from its source, then analyzes the forces that drag the dust particles,and builds the corresponding physical model on the superfine dust production mechanisms.
