摘　　要：在初步分析大陆动力学的基本含义及其与岩石圈动力学关系的基础上,提出了青藏高原大陆动力学8个方面的科学问题,其核心科学问题是:青藏高原的形成是印度板块与欧亚板块碰撞的滞后效应还是大陆板内构造过程;青藏高原不同构造演化阶段是否具有不同的动力学机制;解体的青藏高原岩石圈下地壳何时、何处、如何和为何流动;青藏高原怎样与周边的盆地同步强耦合作用;如何通过青藏高原大陆动力学的创新带动能源、资源、环境、灾害等应用基础理论的创新。On the basis of the preliminary analysis of basic meaning of continental dynamics and relationship between continental dynamics and lithosphere dynamics, this paper proposes 8 very important scientific problems related to continental dynamics in the Qinghai-Tibet plateau. The key scientific problems are. Are Himalaya and the Qinghai-Tibet plateau the result of the India-Eurasia plate collision or continental intraplate orogeny？ Are there various dynamic mechanisms at different tectonic evolution stages in the Qinghai-Tibet plateau？ When, where, how and why does the lower crust of the Qinghai-Tibet plateau flow in the disintegrated lithosphere？ How and why does the synchronous strong coupling happen between the Qinghai-Tibet plateau and its adjacent basins？ How can.we promote innovation in basic theory of continental dynamics in the Qinghai-Tibet plateau and implement innovation of applied basic theory in resources, environment and disaster？
