Abstract: In this paper,we give a general introduction to our recent studies on the gravity field of the Qinghai-Xizang region. Our research works are composed of the three main parts: based on the isostasy principle and the thermal colomn model, we cornputated the undulation of the Moho in terface and the density anomaly of the upper mantle,and assessed the rise of the Himalaya mountain and the corresponding mechanism. Accoording to the residual geoid distribution and the ideal heating convection model, we discussed the force source of the movements of Qinghai-Xizang region and central China.Based on the repeated gravity observations, it is able to detect the rise of the Qinghai-Xizang plateau and the activity of the fault.

Key words: Gravity field, Crustal movement, Qinghai-Xizang plateau
