Abstract

Wind erosion is an important ecological environment problem in arid and semi-arid areas in northern China. The Bashang Area is located in the core area of the agro-pastoral ecotone in northern China, and is a typical wind erosion control area. This study measured the transport fluxes of 13 storms and 8 period-wind erosion at the distances of 50 m and 100 m of downwind(non-erodable boundary) in 2015(tillage farmland) and 2016(oats residues) and predicted the transport fluxes at 50 m and 100 m of downwind based on the RWEQ model. We compared the observed and predicted transport flux to evaluate the RWEQ model. The results show that the wind erosion prediction by the RWEQ model of oats residues management is better than that of tillage farmland for the single events, and prediction of the Q₁₀₀ is better than that of the Q₅₀. For the period wind erosion, the prediction of the tillage farmlamd is better than that of oats residues, and prediction of the Q₁₀₀ is better than that of the Q₅₀. The results indicate that the RWEQ model poorly predicts the small wind erosion events, and there is a low relationship between the predicted and observed values. However, the RWEQ model could well predict large sediment transport for single event and period wind erosion. The RWEQ model can be used as a reference for predicting wind erosion in Bashang Area, Hebei Province. The prediction result of RWEQ model has reference value, and has certain prediction ability for wind erosion in Bashang Area, but it needs further parameter revision to get more accurate wind erosion prediction results.
