摘要Wind is the main factor that affects soil erosion and the severity of wind-sand disasters. Therefore, it is of critical importance to analyze the influence of remodeling topography units on the near-surface wind conditions when studying wind erosion in the road domain and its control methods. The impact of different remodeling topography units on the near-surface wind conditions during road construction is studied by field observations of the railway from Jining to Erenhot. Results indicate that, even after affected by the different terrain units, the near-surface wind profiles are still in accordance with logarithm law or piecewise logarithm law. However, the effective elevation in the logarithm formula is no longer the surface absolute elevation. In addition, the horizontal wind velocity field changes as the terrain changes. In case of windward slope, the wind velocity increases gradually from the bottom to the top, and the increment rate has a linear relationship with the length of the slope. On the other hand, to leeward slope, the wind velocity decreases dramatically just below the top of the slope at first, and then reduces slowly till the bottom.
