Abstract: A brief illumination of contemporary geodynamics and historical geodynamics is presented in this paper. The subdivision ot geodynamics in different research levels is proposed, and general discussions are made on following importent problems: 1. the leveling of the earth and a model of mantle plume, 2. the antisymmetry of global tectonics, and 3. the differential movement on both sides of the longitudinal structure as well as the latitudinal mantle flow.

Key words: Contemporary geodynamics, Tectonic antisymmetry, Mantle plume, Latitudinal mantle flow

摘要： 本文对现今地球动力学和历史地球动力学的研究范畴和特点进行了简要说明,提出了地球动力学研究层次的划分,对现今地球动力学的三个重要问题,即地球的分层问题和地幔涌流模式的构想;全球构造格局的反对称性;经向构造两侧构造运动的差异和纬向的地幔流等进行了一般性的讨论。
