Abstract In this paper, we inverse the spatial and temporal terrestrial water storage changes(TWSC) in the Three-River Source(TRS) region from 2006 to 2015 using the latest CSR data of GRACE RL06. The TWSC results obtained by RL06 are compared and analyzed with GLDAS hydrological model and TRMM precipitation data. The results show that the variation trends of terrestrial water and surface water in Three-River Source region between 2006 and 2015 are 5.2±1.2 mm/a and -3.8±0.9 mm/a respectively. Precipitation is closely related to the change of terrestrial water and is the main reason for the seasonal terrestrial water storage changes; permafrost, as a special aquifer, affects the hydraulic relationship between surface water and underground water. Combined with the surface freeze-thaw data, it is speculated that the permafrost activity causes the difference in the water storage of GRACE and GLDAS.
