青藏高原古岩溶属形成于土下环境,经刻蚀作用剥露地表后,以石林、岩墙等形式广泛存在于山顶夷平面的外围,并不同程度地叠置气下改造特征。根据青藏高原及东邻岩溶区覆盖型岩溶和红色风化壳的剥露情况及改造特征对比,作者认为上述地区覆盖型岩溶从东到西具有良好的一致性,是岩溶双层夷平面的组成部分,其现阶段的不同表现是不同程度刻蚀作用的结果。 The paleokarst formed on the Qinghai-Tibet Plateau is formed in the subsoil environment. After the surface is exposed by etching, it is widely distributed in the periphery of the top of the mountain top with the stone forest and the dyke wall. Based on the comparison of the revegetation characteristics and remodeling features between the covered karst and red weathering crust in the karst area of ​​the Qinghai-Tibet Plateau and the east, the authors believe that the covered karst in this area has a good consistency from east to west and is an integral part of the karst double- , Its different performance at this stage is the result of different degrees of etching.
