摘要
利用我国实测重力值计算完成了全国５＇×５＇格网平均空间重力异常，并结合重力场模型ＷＤＭ９４，利用国内外最新发展起来的快速谱算法确定了我国高分辨率５＇×５＇重力大地水准面ＷＺＤ９４。
In this paper,5'x 5' mean free-air gravity anomalies in the area of China(64maps of 1:1 000 000 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' x 5' gravity geoid WZD94 of China was determined.
