当今中国岩石圈物理学研究中的几个重要问题与思考

我国多年来在岩石圈物理学研究中已取得了一系列的重要成果,并促进了我国地球科学的发展.然而在这21世纪之际,基于国家战略需求和自主创新的方针对岩石圏物理学是挑战,也是机遇.为此,必须厘定其今后的发展导向,并凝炼出前瞻性、并具有带动性的创新性核心科学问题.本文在这样的思维前提下对岩石圈物理学的科学内涵和发展导向进行了较全面的分析、研究和思考,并明确指出当今在这一学科领域应该做些什么,核心问题是什么,又存在哪些关键性的科学问题.研究结果提出,高精度的地球物理场观测与岩石圏内壳、幔精细结构(2维和3维)的刻划;在地球内部力系作用下,深部物质和能量的交换;深部物质运移的物理—力学—化学作用过程及深层动力学响应乃是深化对地球本体的认识和揭示成山、成盆、成岩、成矿和成灾的根本机理所在.为此,在本世纪的上、中叶,在地球科学领域中地球物理学研究必为先导!本文最后对岩石圈物理研究中尚存在的一些问题及困惑进行了分析和讨论,并提出了有关统一规划和观测仪器与设备的自主研发以及有序进行国际合作等方面的意见.

Some important scientific problems and ponders in lithospheric physics research of China at the present time

China has achieved much during recent years in the area of lithospheric physics research and promoted the development of the geosciences.However,in the 21st century,national needs and policy challenges the science of lithospheric physics.I suggest a general analysis,research,and development direction for lithospheric physics and point out clearly the content,core problems,and key scientific problems in this field.The realization of the earth and the discovery of the basic mechanisms of mountains,basins,minerals,and natural disasters depend basically on high-resolution observations of geophysics,the delineation of the fine structure of crust and mantle(2D and 3D) inside the lithosphere,substance and energy exchanges in the deep earth,the process of deep physical,mechanical,and chemical actions,and deep dynamical response.Therefore,geophysics should be the pioneer in the geosciences field in the first half of the 21st century. I end with an analysis and discussion of some problems and difficulties in the research of lithospheric physics.
