Zusammenfassung:The invention relates to a seismic data amplitude compensation method and system. The method comprises the following steps: acquiring seismic data; performing earth surface consistency amplitude compensation on the acquired seismic data, analyzing a stacked section of the compensated seismic data, determining a low-energy region and a high-energy region, extracting at least one single-shot data from the low-energy region and the high-energy region respectively, and according to frequency characteristics of the single-shot data, determining the amplitude of the seismic data according to the frequency characteristics of the single-shot data; performing frequency division on the seismic data according to the principle that the frequency characteristic trends of the single-shot data in each frequency band are kept consistent; and respectively carrying out earth surface consistency amplitude compensation on the seismic data of each frequency band. According to the invention, the problem that the amplitude compensa
