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.
Key words： Blownsand; Dynamics; Engineering.
