Abstract：When gravity survey is conducted in greatly undulate terrain，observed gravity anomaly also includes noise anomalies which are linearly and nonlinearly correlative to landform. The nonlinear correlative noise anomaly results from substances beyond the maximum radius of terrain correction before gravity correction，and these substances are major factors which cause mount-shape gravity anomaly. Then，a new correction method is advanced which removes false anomaly by making terrain continuation. Real data processing result says that the mount-shape gravity anomaly problem which could not be solved before can be settled quite desirably now，mount-shape anomaly being removed roughly.
