Yardangs from Uighur, namely wind troughs, the main role of wind erosion is combined with abrasive products. Qinghai open Terme Rick mining landform located in western Qaidam Basin, forming substance is mainly lacustrine sediments, which of the causes belong to the role of wind erosion. What’s more, climate dry, windy and strong weathering provided favorable conditions for the forming of yardangs. This paper analyzed the open Terme Rick mines Yardangs distribution and morphological characteristics, demonstrated its forming conditions, stating the reasons for the formation and mining landform evolution model, at last ,verified the northeast and southwest mining landform morphological parameters (the length and the width of a strong correlation between the fitting out of the aspect ratio R) On the basis of the measured by least square fitting, having a reasonable analysis of the reasons for its morphological differences.
