Abstract: The observations of wind-sand flow were carried out over a flat sandy surface in the hinterland of the Taklimakan Desert with high frequency automatic sand collectors during April 28, to July 30,2015,and then the spatial difference of wind-sand flow structure was analyzed. The results indicated that:(1) for four dust events,the Aeolian sand as a function of height could be expressed by using a power function for the four sets of sand collectors.However,there were great differences on sand transport rate and the amounts of Aeolian sand at the same height,and the total amounts of Aeolian sand that transported pass unit width also had great differences of the four groups-sand collector. The average amount of aeolian sand at the 25 cm high varied from 3.31~5.35 g, the differences of amount of aeolian sand decreased with height, varying from 0.22~0.49 g at the 100 cm high. The average total horizontal dust flux of the same sand collector for the four dust events ranged form 1.22~233.47 kg/m.This phenomenon was due to the inhomogeneity of wind-sand flow.(2)The sampling frequency had no effect on the structure of wind-sand flow,and the wind-sand flow structure was tending towards stability after 5 minutes.
