英文摘要	According to the three-components teleseismic records from portable digital seismic station deployed in Himalaya mountain chain region, the S-wave velocity structure beneath 46 teleseismic stations are investigated by using transform function method and SA technique. As reliable geophysics evidence, these results help us to understand the geodynamic process of Himalaya mountain region of Tibet. This paper presents Moho topography beneath Himalaya mountain chain region, which indicates tectonic movement and substance exchange are active in the plate boundary regions where the crust remains in the state of imbalance. Although the crustal velocity has significant variation, but Moho velocity discontinuity is not obvious in the plate boundary region. From Himalaya southern slope to hinterland of Tibetan plateau the crust thickness increase from 55 km to 80 km. The Moho have a slight variation along longitude direction. Another evidence that we infer from this study is the tectonics at the MCT formed by the collision of two plate may extend to 80km depth.
