摘要：Shelter forest belts can yield maximum ecological benefits with the smallest occupied area of forests and result in sustainable use of farmland resources. Efficient planning of shelterbelts at various scales is becoming an urgent task in ecological landscape design. Until now, the problems in studies on shelterbelts combined with wind erosion models are associated with conflicts between scientific and practical requirements. Based on previous research results, a case study was conducted in Daling River in northern China. The primary objectives of this study were to use a method for the arrangement of tree species and to investigate the effects of wind erosion prevention. In addition, changes in the trends of the input parameters under multiple wind erosion events were analysed and tested. The results indicated that under a single arrangement of tree species, better shelter protection was provided within the shrub shelterbelt or outside the arbor shelterbelt forest. Under different arrangement of tree species, shrub arranged with arbor belts gave little protection in the leeward side. Arbor arranged with shrub belts could effectively prevent sands from windward side. Cumulative percentiles of sand displacement showed that under different arrangements of tree species, the sand prevention benefit was better than that of a single tree species. In addition, the experimental error was less than 1.00 and there was close correlation between percentiles of sand displacement under multiple wind erosion events, indicating a preferable simulation effect.
