摘要
针对沙漠化(严重时导致沙尘暴发生)这一国家关注的重大环境问题,在简要介绍风沙运动力学机 理研究的主要发展阶段和部分最新研究进展的基础上,提出了风沙运动研究中值得关注的若干关键力学问题.
This paper briefly reviews the latest advancements of investigation on mechanism of wind-blown sands with respect to sand desertification and/or sandstorm which becomes an extremely serious environmental problem and to which Chinese government and international communities have been paid a great attention. Some important topics are put forward for future researches on the mechanism of wind-blown sands.
