摘　　要：通过对近几年马陵山台地磁观测三套仪器(M15、GM4、FHD)受干扰的原始数据的研究分析,总结马陵山地震台地磁观测典型干扰主要有以下几种:磁暴干扰、雷电干扰、台站自有地电观测手段对地磁数据的干扰、观测室空气湿度对不同地磁仪器产生的干扰、台站改造大型金属车辆靠近地磁观测室造成的干扰。经过对比分析,提出解决方法和应对措施,为今后提高观测质量、更加精确地进行数据预处理提供参考和借鉴。Based on the analysis of the original data of three sets of geomagnetic observation instruments (M15,GM4,FHD) interfered in recent years,this paper summarizes the typical interferences of geomagnetic observation in Malingshan seismic station as follows:geomagnetic storm interference,lightning interference,interference of the station’s own geomagnetic observation hand section on geomagnetic data,interference of the air humidity in the observation room on different geomagnetic instruments,and interference of the station’s own geomagnetic observation hand section on geomagnetic data The interference caused by the transformation of large metal vehicles close to the geomagnetic observation room.Through comparative analysis,the solutions and countermeasures are put forward,which can provide reference and reference for improving observation quality and more accurate data preprocessing in the future.
