本文从地球资源利用、自然灾害应对等全球性科学问题的角度阐明了构建公共的地球与空间微物理场探测共享系统、建立地磁定位导航等应用系统以及它们在气象、水文、海洋、地震、生态、环境、医学、工业、农业、交通等相关领域中应用的重要意义。并通过相关领域国内外研究进展和相关科学研究与社会经济发展需求分析,提出了研究设想;预测了地磁研究对我国国民经济建设可能带来的巨大影响和未来发展趋势;最后,提出了积极推进地磁应用的几点建议。 In this paper, from the angle of global resources such as the use of earth resources and response to natural disasters, we establish a common system of exploration and sharing of the Earth and the space micro-physics, establish applications of geomagnetic localization and navigation and their applications in meteorology, hydrology, oceanography, ecology and ecology , Environment, medicine, industry, agriculture, transportation and other related fields of great significance. Through the research progress in domestic and foreign fields and related needs of scientific research and socio-economic development in related fields, the author puts forward the research ideas, predicts the tremendous influence that geomagnetism research may bring to our country’s national economy construction and the future development trend. Finally, Some suggestions of geomagnetic application.
