摘　　要：地电暴作为地电场观测中典型的干扰类型,由于其变化机理的特殊性以及变化特征的复杂性,准确地识别地电暴的变化特征以及研究其变化机制机理,对于地电场台站的日常观测和科学研究,具有非常重要的意义。该文主要利用安徽省地震局嘉山、蒙城两个地电场台站的观测数据,对地电暴变化特征进行分析。发现地电暴具有同步性和广域性,且相比于雷电干扰变化幅度较大持续时间较长。Geoelectric storm is a typical interference type in geoelectric field observation.Due to the particularity of its change mechanism and the complexity of its change characteristics,it is necessary to accurately identify the change characteristics of geoelectric storm and study its mechanism of change.The daily observation and scientific research are of very important significance.This paper mainly uses the observation data of the Jiashan and Mengcheng geoelectric field stations of the Anhui Earthquake Agency to analyze the characteristics of the geoelectric storm.It is found that the geoelectric storm is synchronous and wide-area,and compared with the lightning interference,the variation range is larger and the duration is longer.
