风沙动力与风沙工程学当前研究的热点——主要反映在加深对风沙现象的理解、风沙灾害防治与资源开发三个方面出发,提出了我国在风沙运动力学、土壤风蚀、土地沙漠化的动力机制与过程、风沙地貌形成发育规律、风沙沉积学特征及其形成机制、沙尘暴形成机制以及风沙灾害防护工程技术原理等六个方面的研究建议。

Dynamics and Engineering of Blown Sand and Sand Dunes, which studies natures and characteristics of fluid field of blown sand, boundary conditions, mechanics, processes and the relationl and forms, and engineering approaches to prevent the calamity of blown sand, is of a basic and (or) applied basical branch of science. The present and near future research focuses on three aspects: deepening under standing of blown sand phenomena, principle and measuers of blown sand calamity prevention and development of resources in desert. Based on the trends of studies in this field mentioned above, the author suggests that we should take the dynamical mechanics of blown sand, soil erosion by wind, processes of desertification, form and formation of Aeolian landforms, nature of Aeolian sedimentary deposits and their formation processes, dusts storm, engineering principle and approaches to prevent the calamity of blown sand etc.as main research tasks at present and near future.
