甘肃嘉峪关地震台大地电场观测数据干扰分析

摘要

文章对甘肃嘉峪关地震台2001年至2009年以来大地电场分钟值资料做了全面的分析和整理。对造成观测资料相关性低的电暴（磁暴）、人类活动、雷电、降水、观测系统本身变化（包括更换电极）、电阻率测量、公用接地网等干扰因素进行分析,并做出相关的解释。这将对分析和运用地电场资料进行地震预报有一定的意义。%Minutely value data of Earth＇s electric field of Jiayuguan,Gansu,Seismological Station from 2001 to 2009 are analyzed and classified.Noise factors,such as electric storm（magnetic storm）,human activity,thunder,rainfall,change of observation system itself（including change of electrode）,measurement to resistivity and communal grounding network are analyzed and explained,which will be helpful for making earthquake prediction by analyzing and using Earth＇s electric field data.
