英文摘要	Wind erosion is one of the important aspects of land degradation in arid and semiarid regions. The study of wind erosion variations is very important in choosing and designing biological and mechanical practices for wind erosion control. This research investigates the threshold velocities and soil loss across five different land uses by wind tunnel testing. According to the results, the highest threshold friction velocity (TFV) was related to Ziziphus nummularia natural forests and then agricultural land, rangelands, planted Prosopis juliflora forests, and sand dunes, respectively. Also, the most dust concentration and soil loss was related to sand dunes and then reduced in rangelands, planted P. juliflora forests, agriculture, and Z. nummularia natural forest land uses, respectively.Results of principal components analysis showed three main components controlling the TFV as PC1, PC2, and PC3 with quotas of 51.6%, 20.9%, and 9.7%, respectively (PC1 imposes the largest contribution into TFV). PC1 is composed of the following components: organic matter, Mg, Ca, silt, saturation moisture content, and soil compressive strength. In general, it can be concluded that, among the factors affecting wind erosion, texture, moisture content, and organic matter of the soil have the most significant effects on soil resistance to erosion.
