| 摘 要： | 目前区域重力测量工作正在全国范围普遍开展。我国山区多,地形条件相当复杂,重力测量的地形影响不可忽略。区域重力测量的测点分布稀疏,而且通常是采用自由网,由于这些特点,其地形改正工作不能简单搬用大比例尺规则网的地形改正方法。

| Abstract: | Acomparision among several computer terrain correction methods in regional gravity survey is made, besed on a test conducted in three areas with different topographic complexities. Moreover, the accuracy of terrain correction of the zone of 1-2km calculated with a grid of 1×1km2 is also discussed. |
