通过对2010年5月14日20:00至16日13:00策勒绿洲-沙漠过渡带沙漠前沿气象站一次大风天气过程气象数据和同步进行的方口、全方位跃移、全方位蠕移、BNSE积沙仪积沙数据进行统计分析,结果表明策勒流沙前沿该次大风风向以西北风为主,输沙势分析为低风能环境,为风蚀区域,大风过程表现为风速为脉动状态,方口积沙仪每1 cm高度输沙量随高度分布拟合曲线服从乘幂函数关系,相关系数R2=0.953 5,相关性较好,全方位跃移和全方位蠕移积沙仪16个方位积沙桶积沙量与风向的关系密切,BNSE积沙仪不同高度全方位积沙量随高度分布符合指数函数关系,相关系数R2=0.977 8。
Through the meteorological data of a strong wind at the frontier weather station in Cele Oasis-Desert transition zone at 13:00 on May 14, 2010, at 13:00, the full-scale creeping The results show that the wind direction of the main grizzly is mainly northwest wind before the Cleric sandstorm, and the analysis of the sand transport potential is a low wind energy environment and is the wind erosion area. The windy process shows the wind speed is pulsating, The curve of sediment yield per hectoliter at height of 1 cm with height distribution obeys exponential function, the correlation coefficient R2 = 0.953 5, correlation is good, omni-directional jump and omnidirectional creeping sedimentometer 16 The relationship between the azimuthal sediment yield and the wind direction is closely related to the wind direction. The total sediment concentration at different heights of BNSE sediment analyzer is in accordance with the exponential function with a correlation coefficient of R2 = 0.977 8.
