摘　　要：在以往海陆联编布格重力异常图的过程中,总存在着这样的疑惑,为什么在海陆交互区域异常形态通常呈现不连续的现象。经仔细研读经典教科书[1~2]及相关规范[3],发现主要是对海洋布格重力异常的误读。目前海洋船舷重力测量经空间重力改正所得的空间重力异常已十分接近陆地的布格重力异常,故海陆联编布格重力异常图釆用陆域布格重力异常加海域空间异常的编图方式是合适的做法。Why Bouguer gravity anomaly usually present discontinuous phenomenon in the sea and land interaction area,and there is always such a confusion that is in this area joint editing anomaly map.We find that is a kind of misreading about marine Bouguer gravity correction.It is an appropriate way for joint editing Bouguer gravity anomaly map using the free air gravity anomaly from the ship's rail and the Bouguer gravity anomaly from land,because that is close to.
