| 摘 要： | 新近取得的深反射与全球地震层析成像资料,为地球内部结构和流体通道的研究提供了一些依据．通过研究这些地震资料,可以了解地球内部物质分布状态的几何模式．综合研究表明,地球内存在流体通道网,它连通地球外核、中幔圈、软流圈和岩石圈,是固体地球系统的重要组成部分．这种通道网络象“动脉”那样把地球外核中的流体和热量向外传送,但与热羽说不同的是,不见得有对应的“静脉”存在以保持地幔质量平衡．固体地球作为多层次多要素的巨型复杂系统,其动力学过程要用浑沌理论去解释．研究地球流体活动的轨迹和吸引子,将有助于深入了解地球活动的规律性．

| Abstract: | Recent data of deep seismic reflection and seismic tomography provide new evidences for study of structures and flind pathway of the Earth's interior. Geometric patterns of mass distribution in the Earth can be infered based on analysis of these geophysical data. The analysis shows that there is a network of the fluid pathway exist in the solid Earth, which connect the Lithosphere, the Asthonosphere, Mesosphere and the Core, and should be an impodrit component of the solid Earth system. Likehumans artery, the network transmits fluid (including magma) and heat from the outer core to the surfaCe. However, it is lack of evidence to prove that there would be cormsponding"vein" which transfer heavy mass downward to keep long-term massequllibrium within the Earth. As a huge mulh-comPOnent and complicated system, dynndc processes in the solid Earth should be elucidated by employing the chaos theory. Study of the traectory and attractors of the Earth's flind motion is an important key to understand regularities of the Earth's evolution. |
