Abstract:It is one of the hot international frontier research subjects in Earth science domain to study geodynamical problems by using modern high precision gravity field information. Except for seismology measurements, the gravity can provide us with one effective tool to know accurately and recognize deeply the structures of the Earth’s deep interior. The background and action of the gravity studies using superconducting gravimeters are simply summarized in the paper. The present status and tendency of the international developments as well as the main research achievements obtained under the support of the key knowledge innovation project of the Chinese Academy of Sciences are introduced. Finally, several reference suggestions for how to better use of the gravity information in geodynamics and national requirements are proposed.
