Experimental study on the distribution characteristics of the saltation particle of aeolian sediment in bare tillage

The study bases on Agro-Pastoral mixed regions in Inner Mongolia. The study uses DEM6 pocket three cups wind direction and wind velocity anemometer, LV50 pocket anemoscope that can measure instantaneous wind velocity and average wind velocity in any period. The SC-I dust-collector was also used to collect saltation grains. After sieving and weighting the collection grains, the main variable characteristics of wind movement, such as the percentage of sediment at different altitudes and sediment discharges were analyzed. Based on the study, the results on the particle distribution of saltation process in tillage were obtained. By studying the wind erosion characteristics in the region, some foundations were provided for the further research on the wind erosion dynamics characteristics.
