摘　　要：在多伦县沙漠化土地调查过程中,就其风蚀地貌进行了详细的研究。本文不仅论证了风蚀地貌的形成、类型和分布,而且以翔实的测定数据,并采用克拉瓦洛维克的风蚀强度公式计算了该地区不同景观类型区的风蚀量。以论据为基础,研讨了增加地表粗糙度的方法、成效以及防止或减缓风蚀的有效途径。During the investigation on desertization land in Duolun, winderosion landform has been studied in detail. In this paper, formation, type and distribution of winderosion landform have been discussed. And amount of wind erosion in different type of landscape area has been calculated by use of Cravailovic's formula of winderosion strength according to the full and accurate measurement data. The methods and effect to increase roughness of surface and effective ways to prevent and slow down wind erosion have also been discussed.
