野外流动地磁测量的实践及国内外大量的研究成果表明，地磁有可能成为地震预报的重要手段之一。然而，地磁资料的连续性、完整性、准确性和可靠性还存在着一定的问题，为此，我们对目前流磁测点的定位标记现状进行了较全面的剖析和研究。结果表明：流磁如果没有严格的定位标记，则给测量资料带来严重的不良后果。为了保持野外流动地磁测点的准确性，改进目前测点的定位标记方法已势在必行。本文提出了具体实施方案，包括：自设定位标记；建立石碑；增设副桩(副点)C；选好辅助定位标记等改进措施。

Practice of the field mobile geomagnetic survey and many studying results show that geomagnetic survey may be become one of the improtant approaches in earthquake prediction.However,the continuity,integrity,accuracy and reliability of geomagnetic survey data are still facing some problems.In order to solve these problems,we gave the current status of the location sign in mobile geomagnetic survey a thorough analysis.The results show:if there is no strict location sign in mobile geomagnetic survey,it will cause serious problem.So it is essential improving the current location signs to keep the accuracy of field survey.The specific implement scheme is given here,including:setting up location sign by ourselves;building stone mark;adding secondary mark;choosing good secondary location signs.
