英文摘要	The vertical mass flux profile for wind-blown sand is an important research topic in aeolian physics. It is generally believed that the relationship between sand transport rate and height can be expressed as an exponential function or a power function. However, the accuracy of these models is questionable, and the influence of the focal height on the vertical flux profile is ignored. The Langmuir equation has been widely used to describe the adsorption process of different solid-liquid systems and is one of the most commonly used adsorption isotherm equations. In this study, the Langmuir equation was applied to simulate the vertical flux profile and tested with field observations from the Badain Jaran Desert and the previous three case studies. The simulation effect of the Langmuir equation is better than the exponential function and the power function, and it is applicable for different wind regimes and underlying surfaces. Each coefficient in the proposed equation has an exact physical meaning. This equation can be improved into an extended form (the LangmuirEXT equation) to describe the changing trend of the sand transport rate in the near-bed layer more accurately. The results of this research will provide support for the design of sand control measures and the mitigation of sand disasters.
