Abstract: This paper takes Taklimakan Desert as the research area，carries out informationization formation and normalization calculation for more than 50 years’ historical data （from 1961 to 2010） of 17 weather stations in Taklimakan Desert，transient monitoring data for 5-layer gradient wind along the desert road in recent five years （from April 2007 to April 2010），and monitoring data for 3-layer gradient wind of typical cross-section under seven kinds of wind-preventing and sand-resistance systems of desert road，and do some systematic research for several laws of wind-blown sand movement in Aral-Hotan desert road. The results are as follows： （1） there are spatial correlation between maximum instantaneous wind speed for 10 m height of weather station along the Aral-Hotan desert road and maximum instantaneous wind speed with 4 m height away from road surface for along gradient wind monitoring station and short-term monitoring station，spatial representativeness for plain section is  20-40 km，and spatial representativeness for special sections is 5-10 km； （2） The maximum instantaneous wind speed for windward side along desert road is 1.15～1.30 bigger than leeward side； （3） The law of horizontal distribution for maximum instantaneous wind speed once-in-two-year along desert road is that it gradually decreases from the middle of desert road to north and south，and the maximum value appears between k66.7 and k326；（4） The prevailing wind direction for northern strong wind of desert road is WNW and N，and for secondary strong wind is ENE and NE. The prevailing wind direction of yearly strong wind in the middle of desert road is ENE and NE，and for secondary strong wind is NNW. The prevailing wind direction of yearly strong wind for the south of desert road is W，and for secondary strong wind is WNW； （5）There are a significant difference for the action of seven wind-preventing and sand-controlling systems to sand-blown along desert road，under wind-preventing and sand-controlling system of reed and straw curtain grid，sand-blown wind speed and sand passing critical wind speed for 2 m height are maximum，with 8.0～9.0 m/s and 10.0～11.0 m/s respectively，and effective instantaneous wind speed，which is the biggest contributor to transport sand is between 8m/s and 15.0 m/s； under wind-preventing and sand-controlling system of black soil engineering bag grid，sand-blown wind speed is 4.0～5.0 m/s，and critical wind speed for sand passing is 5.0～6.0 m/s.
