A series wind tunnel experiments were conduced on in typical farmlands around Beijing. The air-born dusts were measured in the fields under different cultivations, tillage managements, cover rates and intersectional angles between wind and the crop rows. The results show that the amount of raising dust increases with the wind velocity by power function; conservation tillage of one crop a year and two crops a year can reduce wind erosion rate than traditional tillage; the increase of cover rate can reduce the amount, and the more the cover,the better the effect; the amount of raising dust can be changed by the angle between the wind and the crop row, and the amount is highest when zero angle, medium 45° angle, and lowest 90° angle. Finally, some countermeasures such as generalization conservation tillage, hold appropriate stubble and straw in land, were proposed for the wind erosion in typical farmland around Beijing.  
