中文摘要	利用2014年7月至8月塔中地区沙尘与扬沙天气下风沙流运动的实测数据,对0 ~ 85 mm高度内风沙流运动进行了研究。结果表明: ① 0 ~ 85 mm高度层,输沙率(Q)随风速(v)增大呈幂函数规律增加,R~2≥0.975 7,且输沙率主要集中在0 ~ 35 mm高度内。②总输沙率和撞击颗粒数的最佳拟合函数为线性函数,R~2≥0.878 2,相关性较好;塔中地区1 min最小临界起沙风速为4.0 m·s~(- 1)。③跃移运动集中在10: 0020: 00,总输沙率最大值出现在12: 0016: 00, 17: 00以后输沙率明显下降。
英文摘要	In this study,a continuous observation on the micro-gradient field of wind-drift sand at 0 - 85 mm height above ground surface in Tazhong, the hinterland of the Taklamakan Desert in the Tarim Basin,was carried out during the period from July to August 2014. The wind drift sand movement under different wind speed and typical wind-blown sand weather was analyzed. The experiments were done by using the measured data of wind-blown sand movement under sandy and dusty weather during the period from July to August 2014. The results are as follows: ① At the layer of 0 - 85 mm height from ground surface, the sand discharge rate (Q) was increased with the increase of wind speed (v) in a power function law,R~2≥0.975 7,and the sand discharge rate was mainly concentrated within 0 - 35 mm height; ② The best fitting functions of the total sand discharge rate and the impact number of particles were linear,R~2≥0.878 2,and the correlation was good. The 1-minute minimum critical sand-drifting wind speed in Tazhong was 4.0 m·s~(- 1); ③ Sand saltation occurred mainly during the 10: 00 - 20: 00 period, the maximum value of total sand discharge rate occurred during the 12: 00 - 16: 00 period,and the sand discharge rate was significantly decreased after 17: 00.
