Earth's gravity field and its application in geosciences is one of the important contents in the fields of Earth sciences. It plays an irreplaceable role in national basic surveying and mapping， disaster monitoring， resource exploration， surface layer coupling， aerospace and other aspects. In recent years， with the continuous innovation of gravity field observation technology， gravity measurement and the corresponding theory， methods and applications have developed rapidly， and fruitful research results have been achieved. The gravity topics of the annual meeting of Chinese Geoscience Union in 2020 are the concentrated display of these achievements （including 42 oral reports and 10 posters）. Based on the reports on this annual meeting， this paper summarizes the latest research progress in the Earth's gravity field and its geoscience application in China in recent years.
