摘要： 本文对0-10厘米垂直高度层内沙量(包括绝对和相对)的分布及变化, 进行了定性和定量分析。在定性分析中, 对影响风沙流结构的三个主要因素(即风速, 总输沙量, 下垫面)展开讨论。在定量分析中, 分别研究了输沙量(或%)随高度的变化规律; 上中下三层输沙量(或密)随风速和总沙量的变化规律; 总输沙量随风速的变化规律。在此基础上讨论了风沙流结构指标, 并对今后研究风沙流结构提了一点想法。

Abstract: The distribution and variation of sand amount(A), absolute and relative, at the height layer of 0-10 cm are qualitatively and quantitatively analysed. In qualitative analysis, discusses three main factors affecting the structure of wind-sand flow, namely wind velocity(V), total transport quantity of sand(TQ) and underlying surface. In quantitative analysis, studies the variation laws of the transport quantity of sand(Q) with height(H), Q in upper, middle and lower layers in the wake of V and TQ, and TQ along with V. On the basis of above analyses, finally discusses the indexes of wind-sand flow structure and raises some idea about the study on the wind-sand flow structure from now on.
