| 摘 要： | 基于青藏高原巨厚的地壳结构和复杂的地球物理场特征，提出依据地震活动与波场标志、岩石层结构与速度场标志、古地磁标志、位场标志、温度场标志、地质与构造标志作为进行青藏高原地体划分的原则．据此，由北向南将青藏高原及其相邻地带划分为７个地体，即柴达木地体、昆仑地体、可可西里－巴颜喀拉地体、羌塘地体、拉萨－冈底斯地体、喜马拉雅地体和恒河平原地体，它们的分布格局与特征对青藏高原的形成、演化和板块运动及动力机制的研究起着重要的作用．

| Abstract: | Based on the great thickness crustal struture and complex geophysical character,this paper points out the principle for dividing terranes in Qinghai─Xizang Plateau according to earthquake activities and wave field sign,lithospheric structure and velocity character,palemagnetic mark,potential field sign ,temperature sign, geological and tectonics character. From north to south of the Qinghai─Xizang Plateau and its neighbouring regions can be devided in seven terranes, ie, Qaidam terrane, Kunlun terrane, Hon Xil-Bayan Har terrane, Qangtang terrane, Lhasa-Gangdise terrane, Himalayan terrane and Ganges Plain terrane. The distribution and character of these terranes have important rools for the studies of the formation and evolution.of the plateau and plate movement and dynamic mechanism. |
