Abstract: Basic geological survey is a public welfare and advanced geological work to obtain the basic geological conditions of the survey area, which is of great significance to mineral exploration planning, development and major infrastructure construction. With the rapid development of China's economy and the continuous advancement of a new round of prospecting breakthrough strategic action, the basic geological survey work will continue to be strengthened, and the achievements will play an increasingly important role. Based on the analysis of the current situation of the basic geological survey achievements collected in the National Geological Archives of China, this paper puts forward some suggestions to improve the level of achievement sharing, strengthen the top−level design of products and improve the ability of information service. Based on the analysis results of geological achievements, this paper discusses the problems faced by basic geological survey, such as insufficient coverage, gap with national needs, insufficient data update, and traditional mapping techniques. It puts forward some countermeasures and suggestions to improve the level of basic geological survey in key areas, provide timely and authoritative basic geological data, and strengthen the research on new methods of geological mapping, so as to better play the basic leading role of basic geological survey in serving national economic construction.
