摘要
利用我国东南地区１１８２２个重力数据、３０″×３０″数值地形模型和ＷＤＭ９４重力位模型，以Ｓｔｏｋｅｓ理论为基础，采用低通滤波方法处理远区影响，计算了中国东南陆缘２．５′×２．５′格网重力大地水准面，其结果与福建、山东的ＧＰＳ水准相比较，精度分别为±０．１２４ｍ和±０．０６２ｍ。
In this paper, the gravimetric geoid of the continental edge in south eastern of China is calculated based on the Stockes' theory using the 30″×30″ digital topographic model, the 11822 gravity data from south eastern of China and the geopotential model WDM94, and processing the remote field effect with the low pass filter. Comparing with the GPS leveling of Fujian and Shandong province, the accuracy is ±0.124m and ±0.062m respectively.
