Assessment of wind erosion hazard in typical transect Erenhot-Zhangjiakou

This paper establishes a natural-factor database on the basis of researching the literature and considering the availability of data, using remote-sensing data and meteorological observation data, and employs the Fuzzy Clustering and expert knowledge to establish an assessment model of wind erosion hazard to assess the wind erosion hazard of Erenhot-Zhangjiakou. The result shows: the trend of the wind erosion hazard in Erenhot-Zhangjiakou is an increasing hazard from southeast to northwest, which is consistent with environmental and climate conditions; the area of severe hazard and intense hazard is 1.80×10⁴ km² and 7.58×10⁴ km² respectively. It takes up the fifty-six percentage of total area, and indicates that the wind erosion has been the serious environmental problem.
