| Abstract: | 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. |
