Wind Erosion on Field in a Semiarid Area of China

Xuewen Huang, Halin Zhao, and Bin Xu


Wind erosion is a frequent phenomenon in Northern China where the climate ranges from arid, and semiarid to dry subhumid. Millions of hectares of land have been damaged from wind erosion. This paper reports the field methods used for measuring the soil loss, and soil flux distribution of wind erosion in Naiman, Inner Mongolia, China. In addition, the soil loss with varying topography and residue cover was measured; soil quality affected by wind erosion was also tested. Typical erosion rates on crop land reach 30 to 200 t ha-1 from winter to next spring. Increasing residue cover reduces the erosion. The erosion rates on cropland created by ploughing grassland reach 500 to 1400 t ha-1 depending on topography. In eroded land, fine soil particles, soil organic matter and nutrients declined. In contrast, the pH value increased. Wind erosion impacts soil properties more severely on eroded sites than on deposition sites.
