| 摘 要： | 根据青藏高原地壳厚度,采用平衡剖面法对地壳伸缩量进行了粗略的计算,表明其水平缩短约1400km,垂直方向伸张约30km或25km.如此巨大的地壳伸缩量证明了青藏高原地壳为弹粘性体,绝非所谓的刚性板块。

| Abstract: | The amount of extension and shortening of the crust of the Qinghai-Tibet plateau is roughly calculated from its thickness using the method of balanced section.The results show that it has shortened about 1400km in the N-S direction and extended 25~30km in the vertical direction.Such a tremendous shortening and extension may indicate that the crust of Qinghai-Tibet plateau behaves as a elasto-viscous rather than rigid body. |

| Keywords: | Qinghai-Tibet plateau Crustal shortening-extension Elasto-viscous body nonelastic deformation rigidity plateau |
