Based on the data of complete Bouguer gravity anomaly and seismic reflection,we obtained a layered interface structure in deep crust down to Moho. Our study showed that the inversion could reveal the interfaces of strata along the survey profile and the directions of regional faults in two-dimension. From the characteristics of the observed topography of the Moho basement,we tentatively confirmed that the uplift of eastern edge of Qinghai-Tibet plateau was caused by the subduction of the Indian plate. 关键词：联合反演相对重力地震数据发震断层玉树剖面地震反射数据布格重力异常
