中国区域地质调查现代化与加强深部调查

从对区域地质调查的任务出发，总结了过去区域地质调查工作的特点，即基本上是沿用传统方式进行的。提出和论述了21世纪中国区域地质调查应有新发展，以适应战略转变的要求，即除去运输、通讯、记录及数字化成图等之外，更应当面向土地资源、矿产资源、地质灾害以及提高环境质量的需要, 用现代地学理论指导进行多学科的调查和采集、整理资料，实现3维多参数填图和理论概括，是关系现代地质科学发展的、具有深远战略意义的事。几十年的调查工作已证明深部的地质构造情况与地表层的观察结果是不一样的，与依据地表地质构造情况推测的深层情况也很不同。今后应加强深部探测，发展深部探测技术，取得不同深度层次的高分辨率成像图案，使人们对地球的认识提高到一个新的高度，形成新的空间—时间观念，以更有效地解决我国及地球的资源环境问题。

On Modernization of the Regional Geological Survey and Deep Exploration Techniques in China

Some characteristic features of the past regional geological survey in China have been summarized in view of its mission,i.e.it has been carried out principally in a traditional way.It is suggested and described that in the 21st century in additon to transportation,communication,recording and digital map making and so on,the regional geological survey should further meet the requiements from land resources,geological disasters,as well as improvement of environmental quality.Being directed by conception of modern geoscientific theory,it should conduct multi-disciplinary investigation,collect and regularize data,so as to realize three-dimensional multi-parametric mapping and theoretic synthesis.Several decades' investigation in China has demonstrated that geological structure in depth is different from that either observed at surface,even at shallow depths,or inferred on the basis of geological structure at surface.In the future, deep investigation should be strengthened,with techniques for deep exploration developed.Obtaining high-resolution images from various depths will enable to people improve their understanding of the Earth to a new level,to set up completely new space-time evolution concept,so that to resolve resource and environment problems effectively.
