摘　　要：通过对江油地震台地电场观测数据的分析,发现观测数据会受雷电、降雨、电阻率、供电、高压直流输电、农田灌溉排水、虾塘等干扰因素的影响而发生变化。对各类干扰数据的变化特征进行总结,有助于排除前兆信息中的干扰因素,提高地电场观测资料的使用价值,夯实用地电场观测资料预测地震的基础。By analyzing geoelectric field observation data at Jiangyou seismic station,it found that observation data can affected by interference factors such as thunder,rainfall,resistivity power supply,D.C.high-voltage transmission,farmland irrigation and drainage and ponds.The summary on the different interference characteristics will contribute to eliminating interference factors,improving the use value of observation data and laying a firm foundation for earthquake prediction by observation data of geoelectric field.
