作为现代地球科学的三大支柱之一,地球物理能够给出地下三维结构,不仅为认识地球提供了基础资料,而且为资源勘查、环境保护和灾害防治服务。尽管地球物理本身存在着反演问题没有唯一解答的困难,并且面临一系列非线性情况,但综合地质地球物理研究以及地球物理的理论、方法和技术的深化与进步,过去、现在和将来都会作出重大贡献。 然而,当前地球物理受到冲击和挑战。西方世界对地球物理工作正开始大规模裁减;中国进入深化改革,地球物理队伍的精减,也势在必行。对此,必须作具体分析,采取适合国情的方针与政策。 对中国地球物理来说,这种挑战也是机遇。当前中国虽然存在着由计划经济向市场经济过渡的种种困难,但规模宏大的国民经济建设已经高速度展开。中国地球物理应该抓住机遇,积极地投入国民经济建设的主战场,在完成各种资源、环境灾害任务的同时,努力提高地球物理水平,加深对地球的认识。
As one of the three pillars of modern geosciences, geophysics can give a three-dimensional underground structure. It not only provides the basic information for understanding the earth, but also serves for resource exploration, environmental protection and disaster prevention. Although geophysics itself has difficulties in solving inversion problems that are not uniquely solved, and faces a series of non-linearities, geophysical and geophysical theories, methods, and techniques for deepening and improving geophysics, past, present and future will be made Significant contribution. However, current geophysics are hit and challenged. Western world work on geophysics is beginning large-scale reduction; China's deepening reform, the reduction of geophysical team, but also imperative. In this regard, we must make a concrete analysis and adopt principles and policies that are appropriate to our national conditions. For China geophysics, this challenge is also an opportunity. At present, although China has all kinds of difficulties in the transition from a planned economy to a market economy, the massive national economic construction has begun at a high speed. China's geophysics should seize the opportunity and actively engage in the main battlefield of national economic construction. While completing various tasks of resources and environmental disasters, China's geophysics should strive to raise the level of geophysics and deepen its understanding of the earth.
