摘　　要：介绍山东地区地电场观测的基本情况,选取2007~2015年的观测数据,对地电场观测干扰进行调研分析。结果表明,日常观测中主要受到电极老化、外线路接触不良、雷电、降雨、高压直流输电、与地电阻率同台观测、游散电流等干扰。针对各类干扰机理提出应对措施,为地电场观测识别干扰及应对提供参考依据。The general situation of geo- electric field observation in Shandong region is introduced,the observation date recorded from 2007 to 2015 are selected and analyzed. The results show that daily observations interferences mainly include electrode aging,bad contact of outside line,lightning,rainfall,high voltage direct current transmission,simultaneous observation with earth resistivity and stray electric current. According to different interference mechanism,the countermeasures are put forward in the paper in oreder to provide reference basis for geo- electric field observation.
