    • Abstract
  • Based on the field observation of wind-blown sand mothion in "100-kilometer wind area" along the Lanzhou-Urumqi Railway, the fresh gales mainly concentrate in spring and summer. The speed of sand-raising wind is for larger than that in desert regions, approximately 9-class wind. The sand transport capacity increases with the height of the wind, which has a good agreement with the experimental results. The sand transport capacity is up to almost 80% of the total capacity below 2 meters. The results of sand particle size analysis show that the form of wind-blown sand motion is bound and peristalsis below 3 meters, and it is mostly suspending over 3 meters.
