厚层连续的岩溶风化壳只能形成于地貌发育的晚期，对应的地貌景观应为岩溶 夷平面．后者具有与 Ｂｕｄｅｌ双面模式相当的剖面结构——由松散的风化壳层和壳下风化 基面组成．就灰岩区而言风化基面即覆盖型岩溶．青藏高原、云贵高原及湘桂丘陵－线 覆盖型岩溶及红色风化壳具有良好的一致性，都是岩溶双层夷平面的组成部分，但处 于不同的后期夷平面分化阶段．不同亚类的覆盖型岩溶和红色风化壳均指示岩溶夷平 面及刻蚀平原的存在．可以作为讨论青藏高原隆升幅度、速率等基本问题的参照系．
Thick continuous karst weathered crust can only form in the late development of landscape, the corresponding landscape should be karst flat landscape. The latter has a cross-sectional structure comparable to that of the Budel bifacial mode - consisting of a loosely weathered shell and a subsurface weathered base. In terms of limestone weathered base surface covered karst. The Qinghai-Tibet Plateau, the Yunnan-Guizhou Plateau and the Xianggui hills-line covered karst and the red weathering crust are in good agreement. They are all components of the karst double-layer razor plane but at different stages of late-stage razor-flattening. Covering karsts and red weathering crusts of different sub-classes indicate the existence of karst flattened surfaces and eroded plains. It can be used as a frame of reference for discussing the basic problems such as the magnitude and rate of the uplift of the Qinghai-Tibet Plateau.
