Aiming at disjunction of microcosmic researches and macroscopical researches and status quo of theory basis researches of Aeolian sand movement near the sand bed, based on plenty of experiment data in wind tunnel, this thesis studies some microcosmic researches including the number of lift-off sand grains percent time percent sand bed area and relative movement parameters of saltating sand grains by combined methods of mechanical and statistical mechanical theories. Then, this thesis develops in advance a relation between the microcosmic researches and macroscopical researches in order to describe truly the theory model of some macroscopical physical variable of Aeolian sand movement.

本文针对当前风沙运动微观与宏观研究相脱节、准确描述近地面风沙运动规律的理论基础薄弱的现状，基于大量风洞实验数据，通过对沙床面单位时间单位面积起跳沙粒数、沙粒跃移运动过程中相关参数等微观问题的研究，力图建立风沙运动微观与宏观研究的联系桥梁，以期能够准确描述风沙运动宏观量变化的理论模型。
