Abstract：Based on GOCO03S, DTM2006, Airy-Heiskanen models and the spherical harmonic method, taking China and its neighboring area as an example, we here calculate gravity gradient in terms of topographic and isostatic influences. The method used in the paper can eliminate the plan model error. Finally, we provide the isostatic anomaly maps, preliminary analysis, and interpretation.
