在地形起伏较大的地区进行磁测时,不能将之等同于平坦地区磁场的分布来进行解释,这一点是人们公认的了。但是,对于起伏不大的地形,常常忽视其影响,将它当作平面异常进行解释。实践证明,即使是弱地伏的地形,对解释结果也会有相当程度的影响。1978年,我们曾引进帕哈塔恰雅等人的曲线延拓方法。就目前来看,该方法是精度较高 It is generally acknowledged that magnetic measurements can not be interpreted in the same way as the distribution of magnetic fields in flat areas when conducting magnetic surveys in areas with large topography. However, for undulating terrain, its influence is often ignored and interpreted as a plane anomaly. Practice has proved that even the weak terrain, the interpretation of the results will have a considerable degree of impact. In 1978, we introduced the method of curve extension by Pachata Chaya et al. For the moment, this method is more accurate
