| 摘 要： | 从全球大地构造力学几何分析和天体演化学研究得知，地球的原始形态是卵形体，因此在向圆球体发展中必然产生两极挤压力成为总应力场。于是形成经向大洋的裂口和纬向褶皱，并出现了构造运动旋回。在此两极挤压中也诱发了岩浆活动和成矿，地震也由此而来。地球在现阶段趋向稳定，人类不必担心将有剧烈地壳构造运动，要爱护地球，节省资源，致力于环境和发展，为后代造福。

| Abstract: | Analysis of the global geotectonic framework by geometric dynamics, coupled with studies of celestialevolution, indicates that the shape of Protoearth was oval, so its evolution toward a sphere brought certainlyabout meridional compression beginning the poles. Such a compression process let to oceanic rifts in ameridional direction while to folds in a latitudinal direction, namely, cycles of tectonic movements. At the sametime, magmatic activities, mineralizing and earthquakes were triggered correspondingly. The Earth of todayhas progressively trended toward stability. And there is no need for man to worry about what is violent crustalmovements will take place in Earth but to take good care of her, economize natural resources and work foreconimic development and environmental protection to benefit future generations. |
