Abstract：On the basis more than ten absolute gravity values of the Himalaya project in the north and the south segments during 2011-2013, gravity dynamic variations are obtained according to the recalculated one-degree term of chromatic polynomial of gravimeter in the network of Gansu, Ningxia and Hexi. The results show: 1) Gravity variation is fairly dramatic in the Qinghai-Tibet plateau, which reflects tendency change on large spatial scales in the process that deep material moves to the northeast. 2) One-degree term of chromatic polynomial remains stable with respect to LCR-G and Burris| CG-5 decreased gradually (it should be calibrated according to the absolute values). 3) A general tendency of change of gravity variation after we used absolute values to calibrate the one-degree term of chromatic polynomial is consistent with long baseline calibration, data analysis is more reliable which is decreased.
