摘　　要：中国西部地域辽阔,海拔高耸,具有复杂的地形和地质构造,有着世界第三极的青藏高原,亚洲最大的沙漠盆地-塔里木盆地。对于青藏高原的隆升机制,一直是全球地学专家争论的焦点,例如,青藏高原是分块隆升还是整体隆升,驱动青藏高原隆升的源动力是什么。地震速度能有效的反应地下介质的性质,因此通过对研究区域莫霍面上下的速度结构分析,可以推断莫霍面上下岩石圈的性质。Western China is vast in territory,towering above sea level which has a complex topography and geological structure,with the world's third pole of the Qinghai-Tibet Plateau,Asia's largest desert basins-Tarim Basin.Qinghai-Tibet Plateau uplift mechanism has been the focus of global experts' debate.For example,the Qinghai-Tibet Plateau is uplifted one block by another? or the overall uplifted? Seismic velocity and effective can response to the nature of the underground media.Through the study the speed of the area under the Moho surface, you can infer the nature of the lithosphere under the Moho surface.
