摘　　要：Planation surfaces includes peneplain, pediment and etchplain, which differ from each other in formation and distribution. The double leveling surfaces theory offered by Budel can be used to explain the landforms in limestone areas. According to Budel, that the residue is the upper layer of a planation surface is very important in studying the formationPlanation surfaces includes peneplain, pediment and etchplain, which differ from each other in formation and distribution. The double leveling surfaces theory offered by Budel can be used to explain the landforms in limestone areas. According to Budel, that the residue is the upper layer of a planation surface is very important in studying the formation environment and weathering crust deposit in planation. In recent years, some researchers have expresses doubt whether it is reliable to use fossils to interpret the rising amount and rate of rise of the Tibet Plateau. It is believed that the primary planation surface can be used as a reliable indicator of land rising.
