摘　　要：文章运用大同中心地震台的地电场观测数据,对大同台6个测道2014年以来的地电场预处理数据进行分析研究。结合工作日志统计日变情况,对雨雪、雷电、大风等天气变化、周边环境改变、外空磁场环境变化以及观测系统本身变化等可能存在的影响因素进行对比分析,得出地电场变化特征及影响因素。Based on the geoelectric field observation data of Datong Central Seismological Station,the preprocessing data of geoelectric field in 6 measuring lines since 2014 have been analyzed and studied.The possible influencing factors of rain and snow,lightning,wind and other weather changes,the surrounding environment change,the outer space magnetic environment change and the change of the observation system itself are compared and analyzed combined with the daily variation of the work log statistics.Some interference characteristics and the specific influencing factors of the geoelectric field variation in Datong Central Seismological Station are obtained.
