摘　　要：地球动力学是研究和探索地球内部物质在力源作用下,呈大尺度的运动行为及其在整体运动中物质与能量的交换、深部圈层耦合、介质与结构变异的物理-力学属性、深层过程和动力机制的一门边缘科学。地球动力学集成了当代众多相关学科和学科交叉领域的高、新学科研究成果,它涉及到成山、成盆、成岩、成矿、成灾和深化对地球本体的认识,它在地球科学研究中占有极为重要的地位。本文通过深入研究、综合集成与剖析讨论了该领域四个重要的基本科学问题,即:(1)地球动力学在地球科学研究中的地位和作用;(2)地球动力学研究的趋势和导向;(3)中国地球动力学研究的方向和任务;(4)地球内部物质运移的力源机制和综合研究。Geodynamics is a frontier subject in the study for the realization of large-scale motion of deep materials under force effect and understanding of the earth that involve the exchange of material and energy,different spheres and layer coupling,physical and mechanical mechanisms of differentiation and regulations in deep media structures and attributes,in deep dynamic processes. Geodynamics is integrated with research results of current high and new technology fields and cross-discipline,and involves the discoveries of the basic mechanisms of mountains,basins,minerals and natural disasters. It plays an important role in the study of the earth science. Four important basic scientific questions are as follows:(1) The role and function of geodynamics in the earth science; (2) The research development trend and direction of geodynamics at present; (3) Development direction and task of geodynamics in China; (4) Dynamical mechanism of substance movement in crust and synthetical study.
