摘　　要：随着现代科技的发展,重力学与地震学、地质学、基础物理学、地球动力学、水文学、海洋学和天文学等众多学科交叉融合并蓬勃发展,是服务国家测绘基准、资源勘探、军事安全及灾害监测等战略需求和基础地球科学问题研究的关键学科,因此掌握重力学的核心技术是国家核心竞争力的重要体现。文章在分析我国重力学学科发展的历史、现状、机遇与挑战的基础上,提出了重力学学科未来发展方向与重点思考内容,涉及海陆天空一体化的立体重力观测技术,海陆天空统一的大地测量重力基准网,地球系统质量迁移与青藏高原动力学问题研究,面向国防安全与太空的重力学,以及发展人工智能等新技术在重力学研究中的应用等。With the development of modern science and technology,gravimetry is growing vigorously and is increasingly becoming an interdisciplinary subject that is closely related to many others such as geology,fundamental physics,geodynamics,hydrology,oceanography,and astronomy.It is now a key subject in giving service to demands in national strategy and fundamental researches in geoscience such as fiducial surveying and mapping,resource exploration,military security,and hazard monitoring.Therefore,owning the core gravimetric techniques is one of the pivots which reflect national core competitiveness.This study first briefly overviews the history and actuality of the growth of gravimetry subject in China and analyzes the chances and challenges.Then some directions of the future developments in gravimetry in China are proposed and some thoughts are shared.These involve constructing gravimetric datum network and corresponding observational technology by unifying ocean-land-space-based means,investigating mass transfer in Earth system and Tibetan dynamics,enhancing contributions from gravimetry to national security and outer space exploration,as well as boosting applications of the artificial intelligence in gravimetry.
