XU Hui_ping 1,Haagmans R H N 2,Bruijne A J T de 2, LIU Wan_song 1 (1.Jilin University, Changchun 130026,China; 2.Faculty of Civil Engineering and Geosciences, Delft University of Technology Delft 2629 JA, The Netherlands)  
EGM96, which was mainly developed by NASA, NIMA and the Ohio State University, is a degree up to 360 spherical harmonic cofficients of earth’s gravitational potential model. This high accurate model was calculated from satellites data, which include altimetry data, tracking data, and so on. GPS data, 30′×30′ surface gravity data, etc. The major advancements in EGM96 were the incorporation of all data into 360×360 geopotential solution, improved model accuracy, offered some important by-products and a new calculation method for the high-degree solutions. In this paper, we firstly introduced the earth gravity model-EGM96, then calculated and interpreted the free-air gravity anomaly of mainland of China using EGM96. In addition, the digital topographic data was used to obtain Bouguer gravity anomaly in the same area. The geological explain was made in the paper.
