Abstract: People have been paid more and more attention to the research of wind-sand flows, and the mass-flux-density profile above wind-eroded sediments research has played an important role. The research on the current development of three different properties about the surface (moving sand, straw checkerboard, gobi) of the mass-flux-density profile research situation has been summarized in this article. Because of different research methods, areas, the efficiency of sand and so on, more than 50 functions have been used on the mass-flux-density profile, including exponential function, logarithmic function, power function and Piecewise function, etc. However, these functions are hardly used in practice because of nearly 3 times difference in the same problem simulation results. According to the existing problems in research, the development trend of the mass-flux-density profile will be come up finally.

Key words: mass-flux-density profile, underlying surface, moving sand, straw checkerboard, gobi
