The invention relates to an estimation method for the volume change of a subglacial lake. The estimation method comprises the steps that L1B waveform data in an SARIn mode of a CryoSat-2 radar altimeter in the corresponding time period are obtained; the surface elevation of a subglacial lake area is calculated through a waveform re-tracking method; obtained surface elevation data are pretreated toremove elevation change anomaly points; the pretreated elevation data are subjected to slope correction through a DEM to remove the error caused by the slope; 100*100 m of grids are finally generatedthrough kriging interpolation, then the elevation change in the corresponding time period is calculated, back scattering energy is added into elevation change values for correction, and the influenceof the back scattering energy to the elevation change is eliminated; and the shape and area of the subglacial lake are obtained through the elevation change values, the elevation change values of thesurface of the subglacial lake of each grid are integrated, and finally the volume change of the subglacial lake in the corresponding time period is obtained.
