摘　　要：雅丹源于维吾尔语,即风蚀槽谷,主要是风的吹蚀作用结合磨蚀作用的产物。青海省开特米里克矿区雅丹地貌位于柴达木盆地西部,形成物质主要为湖相沉积物,形成原因属于以风的吹蚀作用为主的雅丹地貌类型。另外,气候的干旱、多风以及风化作用强烈为雅丹地貌的形成提供了有利条件。分析了开特米里克矿区雅丹体的分布规律及形态特征,以及论证了其形成条件,阐明了该矿区雅丹地貌的形成原因及演化模式。在实测的基础上,运用最小二乘法原理,验证了矿区东北部与西南部雅丹地貌形态参数长与宽的强相关性,拟合出长宽比R,并合理地分析了其形态差异的原因。tAccording to the lasrecord, Yardangfrom Uighur, namely wind troughs, the main role of wind erosion icombined with abrasive products. Qinghai open Terme Rick mining landform located in western Qaidam Basin, forming substance imainly lacustrine sediments, which of the causebelong to the role of wind erosion. What＇ more, climate dry, windy and strong weathering provided favorable conditionfothe forming of yardangs. The open Terme Rick mineYardangdistribution and morphological characteristicare analyzed, demonstrated itforming conditions, stating the reasonfothe formation and mining landform evolution model. Alas,the north- easand southwesmining landform morphological parameter（ the length and the width of strong correlation be- tween the fitting ouof the aspecratio R） are verified. On the basiof the measured by leassquare fitting, rea- sonable analysiof the reasonfoitmorphological differenceipresented.
