中文摘要	通过对策勒风沙前沿风况及输沙数据统计分析,采用回归分析方法,初步揭示了其风沙活动特征。结果表明:单方位0 - 100cm高度集沙仪每层高度输沙量随高度变化服从指数或幂函数关系,0 - 10cm和0 - 20cm高度范围累积输沙量分别占总输沙量的12.43 - 42.88%和23.43 - 64.16%。全方位跃移输沙量主要集中在WNW、W、SW、WSW、NW方位上,每个观测阶段的输沙势与BSNE水平输沙通量呈多项式函数关系,相关性极好,输沙势大小与40cm高全方位跃移总输沙量呈线性正相关关系。单方位集沙仪在0 - 100cm高度累积输沙量与输沙势大小呈明显的指数函数关系。通过塔克拉玛干沙漠南缘风沙前沿风况大小可以预测BSNE输沙通量和近地表全方位跃移总输沙量,对于防沙工程的设计具有重要的理论意义。
英文摘要	Data for wind regime and sand transportation were analyzed and regression analysis was adopted to probe the characteristics of sand - blown activity on sand - blown frontier in Cele. The outcomes show that the relationship between sand transportation at different layers and the height obeys exponential or power function at the range of height from 0cm to 100 cm for sand transportation trapper in single direction. The accumulated sand transportations at the range of 0 - 10cm and 0 - 20cm accounted for 12.43% ~ 42.88% and 23.43% ~ 64.16% of the total amount,respectively. The annual transportation of trapped saltation particles were mainly concentrated in the directions of WNW,W,SW,WSW and NW. During every observation phase,it shows polynomial correlation between the sand drift potential and horizontal sand transportation flux of BSNE trapper,and the correlation is very well. It shows linear positive correlation between sand drift potential and total transportation of saltation particles at the height of 40 cm. In the range of 0 - 100 cm,it shows obviously exponential functional relationship between the accumulative sand transportation of single direction sampler and DP. Sand transportation flux of BSNE trapper and sand transportation in total orientations can be predicted according to wind regime in sand - blown frontier in southern margin of Taklimakan Desert,which has important theoretical meaning in designing engineers in sand hazard prevention.
