We calculate local terrain and isostatic correction using spectral combination and nested different topographic resolutions and determine the free air gravity anomaly grid by the gravity reduction method. The results show that the accuracy of terrain correction calculated by the spectral combination method is the best in the test area, and the accuracy of isostatic correction calculated by nested different resolutions in the central and edge regions is best. When the integral radius is 1° and 2°, there is little difference between the local terrain correction, and the isostatic correction results differ significantly. The accuracy of free air gravity anomaly grid results obtained from the complete Bouguer and isostatic gravity anomalies by gravity reduction is the same, and the accuracy of the results is much higher than that obtained from the direct grid of free air gravity anomalies at ground points.

采用谱组合和不同地形分辨率嵌套的方式计算局部地形和均衡改正, 并利用重力归算方法计算实验区的自由空气重力异常格网。结果表明, 在实验区内由谱组合法计算的局部地形改正精度最优, 在中央区和边缘区采用不同分辨率嵌套计算的均衡改正精度最优; 积分半径为1°和2°时, 局部地形改正的计算结果相差不大, 均衡改正相差较大; 由完全布格与均衡重力异常经重力归算后的自由空气重力异常格网结果精度相同, 较由地面点自由空气重力异常直接网格化得到的结果精度有大幅提升。
