雅丹是沟槽和垄脊相间排列的典型风蚀地貌，雅丹研究是风沙地貌学科的薄弱环节。结合遥感影像和气象数据，对柴达木盆地雅丹地貌的分布、形态特征和发育环境进行了研究。结果表明：柴达木盆地雅丹体形态参数长（l）与宽（w）之间具有良好的正相关关系，即l=3.8685w+7.7109；雅丹地貌的形态受地形、地层性质、气候条件和外力等因素影响；柴达木盆地主风向为WNW和NW，与该区域雅丹的长轴走向吻合，说明研究区雅丹的形成主要靠风蚀作用。
Yardang geomorphology is a typical combination of wind erosion geomorphology with furrows and ridges. Based on remote sensing images and meteorological data, the distribution, morphological characteristics and development environment of yardangs in Qaidam Basin are studied in this paper. The results show that there is a good positive correlation between length (l) and width (w), that is, l=3.8685w+7.7109. The morphology of yardangs is affected by topography, stratigraphic properties, climatic conditions and external forces. The main wind direction of Qaidam Basin is WNW and NW, which is consistent with the long axis strike of yardangs in this area, indicating that the formation of yardangs in the study area mainly depends on wind erosion.
