Embodiments of a method and system for inversion of high-resolution aquifer storage coefficient based on gravity satellite data are disclosed. The method comprises: acquiring gravity satellite data, soil moisture storage data, surface water storage data and other non-groundwater component data, based on a preset region. The method also comprises: obtaining monthly time series of terrestrial water storage anomalies, by inversing the gravity satellite data; obtaining monthly time series of soil moisture storage anomalies, surface water storage anomalies, and other non-groundwater component anomalies; obtaining monthly time series of groundwater storage anomalies; and obtaining monthly time series of groundwater level anomalies in different aquifers. The method yet comprises: obtaining random sample values of storage coefficient by a stochastic simulation; obtaining correlation coefficient and Nash-Sutcliffe efficiency coefficient between random value of groundwater storage trend after a forward modeling and groundwater storage trend in the gravity satellite time-variable signal; and obtaining an inversion result.
