地球科学

Digital earth, emerged at the end of last century, is a new strategic orientation for quantitatively studying the earth and a crosscutting multidisciplinary field of space science and technology, information science and technology, earth science etc.

数字地球是20世纪末期问世的定量化研究地球的一个新的战略方向，是集空间科技、信息科技、地球科学等于一体的交叉学科领域。

Geo physics Major branch of earth science that applies the principles and methods of physics to the study of the Earth.

地球物理学地球科学的主要分支，用物理学的方法和原理研究地球。

The physics of earth interiors and geodynamics are of great importance in geosciences.

地球内部物理学和地球动力学在地球科学研究领域里占有重要地位。

Geophysical imaging is not only one of the spot and the most progressed theory and technology i...

地球物理成像不但是当今地球物理勘探领域最引人注目、发展最快的理论技术之一，也是地球科学的一个前缘发展方向。

On the other hand, the Earth is no longer the sole physical place to obtain or examine our knowledge in earth sciences, other planets, stars or space between these cosmic objects can also provide additional or terrestrially not available laboratories to test hypotheses or verify various theories in natural science.

因此要检验地球科学中的一些基本模型、理论或假说，观察自然环境在不同物理条件下的演变，再也不能仅局限於对地球本身的观测，因为地球已非唯一的实验室。

In this paper, the necessity of the foundation of a new crossed discipline——Tectonogeo-physics which was proposed by author more recently, and its theoretic and practical signifi-cance to develop the earth science are expounded from the brief review of the history on thecrossed combination between geotectonics and geophysics .

本文从大地构造学与地球物理学交叉结合的简要历史回顾，阐述了笔者新近提出建立一门新的交叉学科——构造地球物理学的必要性和对地球科学发展的理论与实际意义。
