腾格里沙漠东南缘输沙势与最大可能输沙量之比较

摘要/Abstract

摘要： 利用腾格里沙漠东南缘沙坡头站20年风况自记资料,计算了输沙势和最大可能输沙量,深入研究了二者之间的定量关系。另外,通过矢量合成法则,对合成输沙势和合成输沙量的关系也做了进一步研究。输沙势和最大可能输沙量不仅在量值上关系显著,而且在16个方位上的分布规律也存在一定的相关性。

Abstract:

Based on the detailed wind data from 1980 to 2000 at Shapotou station in southeast edge of Tengger Desert, the sand drift potential and the maximum possible transport in this region were calculated, and their relationship was analyzed. In addition, the resultant sand drift potential and the resultant maximum possible transport were further studied. It was found that the sand drift potential has a remarkable relation with the maximum sand possible transport both on its value and the 16 different directions.

Key words: sand-blown activity, sand drift potential, the maximum possible sand transport, Tengger Desert
