摘　　要：中国地球深部物理学与动力学的研究始于20世纪50年代,半个多世纪以来这一创新性工作取得了重大进展.基于我国大陆陆缘和邻近海域壳、幔结构的分区特征和不均匀性展布,特别是在印度洋板块、太平洋板块和欧亚板块的相互作用下形成了一个破碎镶嵌的块体组合.因为资源、能源、灾害的形成和动力机制均为地球内部物质与能量的交换所致.为此表明:地球内部结构和深层动力过程的研究与探索在成山、成盆、成岩、成矿和成灾过程中有着极为重要的作用.半个多世纪以来我国在该领域中,不论是理论、方法和探测技术诸多方面已有着较丰富的积累,并首先提出了16大论点与论据,它们是重要的科学导向.这不仅促进了我国在20世纪百年里地球科学的发展,而更为重要的是提出了一系列的有待研究和探索的科学问题.在21世纪的进程中,地球物理学必须牢牢地把握国家战略需求和自主创新,方能有所发现和突破.为此我们必须深化对地球本体的认识.For the first time research the deep physics of Earth and dynamics in China was since 1950 sof the 20st century, during the last 50 years this inilative work has gained great progress. In vieus of the regional characteristios and inhomogeneous distribution for structure of crust and upper mantle in the eontineat margin and close to sea area of China, especially interaction between the Indian ocean plate, pacific plate and Eurasian plate, broken mosaic blocks was fomed in the Eurasian continent. Because its fomation and dynamical mechanism of natural resource, energy source and disaster are the result of exchange of substance and energy. Deep process and dynamical response in the Earth＇s interior associated with formation and generation of ranges, basins, rocks, minerals and disaster are very important. Weare accumulate a mealth on the theory, method, and sounding technology in this field since half century, for this reason it has also first to put forward the sixten majon thesis and evidence, Beeuse they are the sigmificant scientific guide. It was no only promoted the development of Earth sciences in hundred years of 20st centry and it has also put forward a series of scientific problems for research and probe. Geophysics must firmly grasp the national strategic requirement and self innoration of our country with a breakthrough thread can be found in the course of 21st centry. To this and we most improve the understanding of Earth＇s itself.
