Abstract

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.
