A study of the standard system of regional geological survey

Geological mapping is a fundamental geological work characterized by advanced, public welfare-oriented, strategic and multipurpose nature, with the purpose of finding out national basic geological condition. It provides significant support in every aspect for resource prospecting, environmental protection, engineering construction, city planning, territorial development and utiliza-tion as well as the development of geoscience. A thorough technical standard system is an important technical support for regional geological survey. With the technical development of geological mapping over the past half a century, a well-developed technical standard system has been built. Nevertheless, as the development of economy and technology is very fast, the present geological mapping technical standard cannot keep up with the development of the practical work. A series of problems have occurred; for example, the present technical standard cannot meet the demands of the present geological mapping work; the geological mapping technical standard is discrepant or not perfect. Under the new situation, according to the development experience of geological mapping technical standard system over the past half a century, and the study of the advanced ideas of geological mapping techniques, methods and standards from some developed countries, in combination with China's actual situations and demands of practical geological mapping work, the authors established the geological mapping standard systematic framework and put forward some suggestions for its renewal and improvement based on analyzing and arranging geological mapping technical standards with the purpose of satisfying the demands of modern geological mapping.
