摘要
本文扼要回顾了风沙流的研究历史；简明评述了颗粒运动特征、风沙流结构、输沙率模型、起沙风模型、表面气流变化、风沙两相流等研究现状内容；就目前研究中存在的问题、研究趋势等方面作了探讨。
This paper briefly reviews the study history of aelian sand transport processes firstly.Then the study status is summarised and discussed at length by six aspects:①features of grain movement,②the distribution of mass flux with height,③modes of transport rate,④the threshold shear velocity,⑤the near-bed wind profile with saltating grains,and ⑥the 2-phase flow of gas-particle.At last,the authors analyse the problems in present study,and suggest the further trends of study. \ \
