风沙流输沙通量垂向分布研究——以塔克拉玛干沙漠南缘流沙地表风沙流观测为例/Vertical Distribution of Aeolian Sand Mass Flux based on Field Observation at Southern Rim of the Taklimakan Desert[J]

, 2012
于2010年4—6月在塔克拉玛干沙漠南缘策勒绿洲外缘流沙地进行风速、风向和输沙量同步观测,利用观测到的28组数据对输沙通量的垂向分布进行研究。结果表明,在4.5～8m.s-1的风速区间内,总输沙率随风速增长速率较慢,大于8m.s-1时增长迅速。在较小风速时,4个高度层（1cm、3cm、9cm和19cm）的输沙比率变化不明显,当风速大于6.6m.s-1时,1cm和19cm高度输沙比率的调整较为明显,前者减小而后者增加,中间两层（3cm、9cm）则维持一定波动 ...
