In this paper,5'×5' mean free-air gravity anomalies in the area of China(64maps of 1:1000000 standard format) were calculated by using gravity data in China. To meet the need of determining the orthometric (normal)height by using GPS technique, comtechnique,combining with the gravity field model WDM94 and using the latest developed fast spectrum calculation method,the 5×5' gravity geoid WZD94 of China was determined.
