[Objective] In order to analyze the differences of sand flow structure and characteristics of grain size of sand transportation particles near ground surface on three different landscape types, which can be used by providing theoretical basis for setting up sand transportation models.[Methods] We carried out the field observation on wind velocity gradient and sand transportation rate on Cele desert-oasis ecotone, and fitted regression functions.[Results] There was an exponential or logarithm function relationship between sand transportation rate or sediment flux and height at the range from 0-200 centimeters above ground surface on mobile sandy ground. An exponential functional relationship was found between sand transportation rate or sediment flux and height near surface on semi-fixed sandy land and the fitting degree was moderate and well moderate degree which was a bit worse than that on shifting sandy ground. There was polynomial functional relationship between sand transportation rate or sediment flux and height near ground surface on fixed sandy land and the fitting degree was between medium degree and worse degree.[Conclusion] When the mean wind velocity was comparatively greater, an exponential relationship was always detected between sand transportation rate and height and the fitting degree was better than that in phases with slower wind velocity. Whereas on vertical or horizontal directions for sand saltation and creeping sand particles near ground surface, the sand transportation rate and mean grain size on different heights became smaller and finer with increasing distance to ground surface or shortening distance to oasis on horizontal distance. Sorting effect of sand transportation particles on shifting sandy land was better than that on semi-fixed and fixed sandy lands on horizontal direction, which were most belonged to moderately well sorted. The sand has became finer skewed when the sand transportation particles is nearer to the oasis. The skewness of all sand transportation particles including saltation and creeping particles is in the range between -0.06 and 0.05. The kurtosis is in the range from 0.92 to 1.05, which belongs to mesokurtic.
