摘要:为研究乌兰布和沙漠流动沙区0-50cm风沙流结构,揭示流动沙区风沙流的运动规律,在对乌兰布和沙漠流动沙丘风沙流实测的基础上,运用拟合曲线和拟合方程等方法对0-50cm垂直高度内的风沙流结构进行分析。结果表明:(1)0-50cm总输沙量与各高度层的输沙量与风速均呈幂函数关系。(2)各高度层输沙量与高度呈指数递减关系。(3)上、中、下3层的输沙量均与总输沙呈幂函数递增关系。
In order to study wind-sand flow structure of 0-50 cm in the mobile sand dune of Ulanbuh desert, to reveal motion law of wind-sand flow in the mobile sand dune. On the basis of data measured through wind-sand flow structure in the mobile sand dune of ulanbuh desert, the author analyzed wind-sand flow structure of 0-50 cm vertical height using method of fitting curve and the fitting equation etc. the result showed that: (1) The sand transporting rate in 0-50 cm height inside and each high layer all presented power function relation with wind velocity. (2) The sand transporting rate in each high layer and height presented decreasing function of exponential relation. (3) The sand transporting rate in upper, middle and low layers presented the power function relation with the rate of sand transporting in 0-50 cm height inside.
