    Abstract:

    [Objective] A risk assessment on soil wind erosion throughout Hebei Province was conducted to provide some scientific bases for prevention of land degradation and air pollution induced by wind erosion. [Methods] Based on the GIS and remote sensing, the soil wind erosion of Hebei Province in 2009 was evaluated using the wind erosion model recommend in the first national water survey. [Results] The districts assessed at tiny erosion level accounted for 65.36% of Hebei Province, which were mainly distributed in Hebei plain, the Taihang and northern mountainous regions of Hebei Province. The districts with slight erosion were mostly distributed in Bashang plateau and the northwest basins of Hebei Province, covered 12.46% of the whole province. The moderate and strong wind erosion had the smallest area with less than 0.1% coverage throughout Hebei Province, these districts located at the sandy areas of the Northern Hebei Province. No extra-strong and severe erosion in Hebei Province were found. [Conclusion] Wind erosion in Hebei Province had obvious spatial variation, comparating with the highest erosion in the northwest part, moderate level in the southern area and lowest level in the northeast part of the province.
