摘要利用了双输入单输出法,融合处理了我国某地区的重力异常和地形资料两类数据,结合WDM94地球重力场模型和63个高精度GPS水准数据,计算了该区域的似大地水准面。 The double-input single-output system is used to combine gravity anomaly data and to get the local residual geoid in some area of China; the global Earth＇s gravity field model WDM94 and 63 GPS/leveling data are also used to calculate the quasi-geoid. At last, the local geoid heights are compared with the observed ones derived from 29 GPS/leveling data that not applied to the construction of local quasi-geoid.
