自然资源时期:大数据与地球系统科学——再论全面发展时期的勘查地球化学

Natural resources period: Big data and systematic science of the earth——More on exploration geochemistry during the overall development period

中国勘查地球化学全面发展的重要标志和本质特征是大数据信息与地球系统科学。勘查地球化学的全面发展坚持资源与环境并重方针,真实生动地反映国家经济社会发展的历史轨迹,在科学技术领域具有典型意义。自然资源时期地质工作关于资源内涵从矿产资源、国土资源到一切自然资源,关于环境内涵从地质环境、国土环境到包括山水林田湖草生命共同体在内的一切自然环境。本文继2008年对此有所评述后,在国家自然资源部成立之际,地质工作面临深刻转型之时,从大数据信息科学与自然资源地球化学调查、建立地球系统科学指导的自然资源地球化学理论体系与自然资源地球化学评价体系,以及针对自然资源领域重大科学问题,深化地球化学应用研究与理论研究,构建完善的科学体系等若干值得注意的方面再次就此议题加以评论。勘查地球化学的长期目标是通过大数据信息与地球系统科学研究揭示自然资源与自然环境状况,实现对地球资源的科学开发、合理利用和整体保护,创造人类与地球和谐共处的生存环境。由此,转型和升级贯穿中国勘查地球化学发展的全过程。地球化学将以形态和内涵的系统性、综合性、整体性作用,以及应用实践的多目标全方位面貌出现在国家行业部门与科技领域,极大地拓展和深入经济社会发展各个方面。勘查地球化学以方法技术优势实行大调查、大数据、大应用战略,建立大环境、大生态、大地球观,向大地质、大资源、大科学转变,为解决自然资源与生态环境问题提供地球化学方案,将全面发展时期的勘查地球化学从大数据信息应用优势和地球系统科学理论高度提升到"大地球化学"境界。

The important marks and essential characteristics of China's exploration geochemistry are big information and systematic science of the earth. The overall development of exploration geochemistry persists in the policy of laying equal stress on resources and environment, truly and actively reflects the historical locus of the development of national economy and society, and has typical significance in the field of science and technology. During the natural resources period, the connotations of geological work related to resources are from mineral resources, land resources to all natural resources, whereas the connotations of geological work related to environment are from geological environment, land environment to all natural environments which include life community of mountains, water, forests, cultivated land, lakes and grass. At the time when the Ministry of Natural Resources is established and geological work is faced with deep transformation, the author, following writing a comment on this problem in 2008, here makes another discussion on this topic in some aspects which are worthy of attention, such as big data information science and geochemical survey of natural resources, establishment of geochemical theoretical system and geochemical evaluation system for natural resources guided by systematic science of the earth, important scientific problems aimed at the field of natural resources, deepening geochemical application research and theoretical research, and establishment of perfect scientific system. The long-term aim of exploration geochemistry lies in revealing the situation of natural resources and natural environment, realizing scientific development, and rational utilization and integrated protection of the earth's resources by means of big data information and systematic science of the earth, thus creating an environment that mankind can harmoniously coexist with the earth. Therefore, the whole process of the development of China's exploration geochemistry will be permeated with transformation and upgrade. Geochemistry will emerge in national professional department and science and technology field with the multi-purpose and all-round appearance characterized by the role of systematic nature, comprehensive nature and integration as well as application practice, thus extremely expanding and deepening its role in economic and social development. With its technological advantages, exploration geochemistry will implement big survey, big data and big application strategy, establish big environment, big ecology and big earth outlook, and transform itself into big geology, big resources and big science, so as to provide a geochemical scheme for solving problems of natural resources and ecological environment and promote exploration geochemistry in the period of overall development from the advantages of big data information application and the height of systematic scientific theory to the realm of ‘big geochemistry'.
