摘　　要：以GPS、大面积水准、流动重力测量、跨断层流动形变测量等方面的监测和研究成果为主,围绕青藏块体和中国大陆地壳的运动学特征、动力学特征、震源机制以及孕震机制进行了探讨和研究。多方面的研究结果显示,印度板块对中国大陆的碰撞和挤压,是青藏块体隆升及其周边地区地震孕育和发生的主要动力来源,并通过多方面研究结果的综合分析,提出了"坝体决口孕震模式"的假说。This paper is focused on kinematic and dynamatic characteristics, source and seismogenic mechanisms of the Qinghai-Xizang block and the crust of continent of China, based mainly on the data and available research results on GPS, large area leveling, mobile gravity observation and mobile deformation observation across faults. The research results from various aspects show that the collision and compression to continent of China by Indian plate is the main power source for the Qinghai-Xizang block uplifting and earthquake genesis and occurring in the area around it .Based on a comprehensive analysis for research results from various aspects ,a hypothesis of ' Dam body branching mode for earthquake genesis 'is proposed.
