在对浑善达克沙地南缘多伦县沙漠化土地调查中,就其风蚀地貌进行了详细的研究,不仅论证了风蚀地貌的形成、类型和分布,而且实测了不同类型区的风蚀量数据。并采用克拉瓦洛维克的风蚀强度公式计算了该地区风蚀量的理论值。以测定数据为基础,研讨了增加地表粗糙度的方法及防止或减缓风蚀的有效途径,并且具有在同类地区示范推广作用。
In the investigation of the desertified land in Duolun County, southern edge of the Hunshandake Sandy Land, the wind erosion landforms were studied in detail, which not only demonstrated the formation, types and distribution of wind erosion landforms, but also measured wind erosion data of different types of areas . The theoretical value of the amount of wind erosion in this area is calculated by using the wind erosion intensity formula of Kravvarov. Based on the measured data, the methods of increasing the surface roughness and the effective ways to prevent or slow down wind erosion are discussed, and the model has the function of promoting the same kind of area.
