大陆科学钻探与中国第一口科学钻选址

Continental Scientific Drilling and Location of the First Superdeep Drilling in China

大陆科学钻探是一项堪与航天技术媲美的浩大系统工程。它的实施具有深远的科学和经济意义。通过介绍国外大陆科学钻探的现状和成果，阐述大陆科学钻探对地球基础科学、其他自然科学研究所具有的重大促进作用，从而为开展我国第一口大陆科学钻探，缩短与国外先进水平的差距提供有益的借鉴。

Since 1960s,the continental scientific drilling projects have been carried out in many countries such as USA, former Soviet Union, Germany and Japan, with over fifty holes in the world so far. The first continental scientific drilling project in China determined in Donghai County of Jiangsu Province signifies much scientific and economic values to basic geology and local economic development. Through the first superdeep drilling project, new understandings including the deep structure, crustal movement, geophysical changes and mineralization and conditions of the earth will be obtained on the basis of the results from foreign superdeep drilling holes. In order to shorten the technological and economic gaps between China and the developed countries, the first project can be used to solve four scientific problems present day China and to improve the national research levels of geoscience and technology. So, Dabie Sulu orogenic zone for it has perfect geological and geographical setting among twelve locations in China is determined as an inexorable selection for the first project. As a best location, Donghai County,one of three selective regions in Dabie Sulu orogenic zone will be becomes a site of the exploration and study of the earth. At present, the operational works for the earlier stage of the first project in Donghai area are in progress. Mang progresses will be made as the first superdeep drilling project.
