青藏高原夷平面形成的时代、性质和原始高度等是解决高原隆升这一世界瞩目课题的关键。李吉均等指出夷平面在高原隆升的研究中有重要意义。杨逸畴、李炳元等曾提出高原上有山原面和盆地面两级夷平面。Shackleton和常承法认为仅有一级夷平面(4500～6000m),时代在10MaBP以前的中新世。早在60年代本文作者之一就认识到古岩溶研究是高原隆升的有力证据。1994年本文作者又根据当时已知数据也撰文指出高原夷平面(包括岩溶面)可以追溯到15MaBP,但由于测年数据有限未能对夷平面性质及原始高度做深入的讨论。
The age, nature and original height of the flat surface of the Qinghai-Tibet Plateau are the keys to resolving the world’s attention in the uplift of the plateau. Li Ji et al. Pointed out that there is great significance in the research on the uplift of the barren plateau in the plateau. Yang Yi domain, such as Li Bingyuan put forward the plateau on the mountain and the surface of the basin two razor surface. Shackleton and Chang Cheng-law believe that there is only one level of razed surface (4500 ~ 6000m), the era before 10MaBP Miocene. As early as the 1960s, one of the authors of this paper realized that paleokarst research is strong evidence of plateau uplift. In 1994, the author also pointed out that according to the known data at that time, the plateau surface (including karst surface) can be traced back to 15MaBP. However, due to the limited dating data, the nature of the plateau surface and the original height can not be discussed in depth.
