| 摘 要： | 对前人提出的多种地球动力学机制特别是地幔对流说进行剖析,提出板块运动地球动力来源于地转离极作用和旋转半径变化造成的地转不同步作用,并受到刚性岩石圈板块应力平衡作用、惯性作用和弹性作用等内在规律的制约,另外规律性的固体潮作用和偶然性的陨石撞击作用是影响板块运动的附加应力因素。

| Abstract: | According to the distribution of lithospheric plates and their known evolution, the author analyzes the basic characteristics of plate motion as well as a variety of geodynamic mechanisms proposed by predecessors, specifically mantle convection. The author proposes that the earth dynamics of crustal movement comes from "unsynchronized action" caused by the "pole-fleeing" of the earth’s rotation and the change of the radius of gyration, and that the earth dynamics are also affected by the inherent laws of the rigid lithospheric plate, such as stress balance, inertia and elasticity. In addition, the role of regular tidal and the occasional meteorites are additional stress factors on plate movement. |
