大陆科学钻探的现状及展望

１．大陆科学钻探是国际岩石圈动力学计划的重要组成部分，是当代地球科学的重大前沿之一，是一项划时代意义的地学高科技系统工程。大陆科学钻探不仅具有直接揭示地壳内部组成、结构、构造、流变学、流体作用、热历史，应力及应变机制以及重塑地壳与岩石圈动力学的重大理论意义，并且具有充分利用地下资源、减灾及保护环境的实际经济价值．２．大陆科学钻探在世界范围内实施３０年来已取得巨大进展，解决深部水资源、深部流体资源、深部地热资源、壳幔过渡、岩石圈动力学及变形、地球历史、生物圈及环境变化、地应力、地下强磁区、矿床成因以及盆地演化、碳氢化合物成因与迁移等科学问题已成为世界性地质目标。３．作为地质大国，面临地球科学新挑战以及２１世纪资源、减灾及环境的需求，填补中国大陆科学钻探的空白已成为当务之急。４．根据需用科学钻探解决的中国关键性深部地质问题，提出选址原则及十大选区（域），并对中国大陆科学钻探的战略目标提出切合国情的建议。

PRENSENT SITUATION OF CONTINENTAL SCIENTIFIC DRILLING IN CHINA AND ITS PROSPECTS

Continental scientific drilling, both one of the frontiers in contemprary geosciences and a system. atic program of High science and technology for geosciences, plays an important part in the international Lithosphere Dynamics Projects (ILDP). Continental scientific drilling provides not only great theoretic significances in revealing the composition, texture, structure, rheology, fluid processes, thermal history,stress and strain mechanism within the crust and rebuilding the dynamics of the crust and lithosphere, but also economical value in full utilization of resources, geological hazard reduction and enviroment protection.(2) In the past 30 years, great progresses have been gained, owning to the globally undertaking of the continental scientific drilling. To solve such problems as deep waster resources, deep fluid resources, deep geothermal resources, crust-mantle transition, lithosphere deformation and dynamics, carth history,changes of biosphere and enviroment, stress, strong magnetic field in the crust, genesis of mineral deposit,basin evolution, genesis and transportation of hydrocarbons and so on have been the international goal. (3) Confronting with the new challanges of earth sciences and demands of hazard reduction and envioment protection, fully engaging in continental scientific drilling project should be the first of all tasks for China as a great geological country.(4) According to the key deep geological problems in China which need to be solved though continental scientific drilling, the principles of site selection and 10 selected areas have been put forward. Finally,we propose the strategical goals of continental scientific drilling which are suitable for the present sitution of China.
