By sorting out the observation data of geoelectric field at Changli, Yangyuan, Dabaishe, Xingji, Feixiang and Luanxian seismic stations in Hebei Province, through processing of data, log query, and investigating the interference source, we summarize the forms of various interference sources and interference mechanism such as line fault, power line interference, lightning disturbance, hvdc, and geoelectric storm in the observation of geoelectric field and then put forward the method for eliminating the interference. It provides the reliable basis for effectively distinguishing the interference of the geoelectric field, extracting anomalies and predicting earthquakes.
