| 摘 要： | 本文依据在青藏高原存在第四纪大陆冰盖的基础上,给定了3个不同厚度的冰盖,应用弹性板模式模拟计算了大陆冰盖消融前后的地壳均衡过程。计算结果表明,由大陆冰盖消融可能引起的高原隆升最大不超过700m。因此,就整个高原的隆升幅度来说可忽略其影响。但由于冰川消融前后高原负荷发生了变化,导致了隆升速度的相应变化,因而引起地表侵蚀强弱程度的不同及其它一些地质现象是不能忽视的。

| Abstract: | Under the premise of the fact that the Quaternary continental sheet existed in
Qinghai - Xizang plateau. based on the elastic plate model, the author, considering the
three sorts of the thickness of the glacial sheet, calculates the subsidence and uplift of the
plateau caused by them. It has been shown that the maximum of the uplift of the plateau
brought about by the thawing of the continental sheet is no more than 700 meters. There-
fore, as the uplift of the whole plateau has been concerned, we can ignore the effects of
the glacial sheet upon the uplift of the plateau, However, we cannot ignore some phenom-
ena (for example, the changes of the crustal erosive intensities) because of the changes of
the uplift velocities caused by the glacial thawing. |
