| Abstract: | Dynamics and Engineering of Blown Sand and Sand Dunes, which studies natures andcharacteristics of fluid field of blown sand,boundary conditions, mechanics,processes andthe relation landforms, 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 futuer re-search focuses on three aspects:deepening understanding of blown sand phenomena, prin-ciple and measuers of blown sand calamity prevention and development of resources indesert.Based on the trends of studies in this field mentioned above,the author suggeststhat we should take the dynamical mechanics of blown sand, soil erosion by wind,pro-cesses of desertification,form and formation of aeolian landforms,nature of aeolian sedi-mentary deposits and their formation processes,dusts storm,engineering principle and ap-proaches to prevent the calamity of blown sand etc. as main research tasks at present andnear future. |
