三维速度结构的研究现状和展望

本文评述了三维速度图像研究的现状,简要地叙述了在全球尺度、大尺度和区域尺度内三维速度图像重建所取得的主要成果.笔者在介绍了三维速度图像同地球科学其它领域的关系之后,在对未来的展望中认为,为板块构造和地球动力学这样一些基本的地学问题提供直接的地震学的证据将是一个长期的目标,并为此提出了三个要解决的问题,还针对我国现有条件提出了供选择的参考课题.

THE RESEARCH SITUATION AND A PROSPECT ON THE THREE DIMENSIONAL VELOCITY STRUCTURE

This paper gives a review of the research situation on the three dimensional velocity images and the main results obtained in the range of global scale, large scale as well as regional scale.In consideration of the relation between three dimensional velocity images and other field of Earth Sciences, the author suggests that it is a long target providing direct seismological evidence for some fundamental problems such as plate tectonics and dynamics of the Earth. With the purpose of this auther offers also three problems to solve and some reference choice projects.
