对2009 年10 月～ 2010 年5 月高邮地震台地电场观测中出现的一种不明原因的大幅度扰动干扰进行了分析讨论。经过初步分析、干扰源模拟定位、干扰源测试、干扰源现场调查等途径，确定了干扰源位置和干扰产生的原因，并对该干扰现象进行了排除处理。

The paper analyses and discusses a kind of large amplitude unexplained interference source that appeared in the geo-electric field observation in Gaoyou Seismic Station，during October 2009 to May 2010． After the preliminary analysis，the interference source simulation，the interference source test，and the interference source survey，the position of the interference source and the reason of the interference production were determined，and the interference phenomenon were screened finally．
