摘　　要：主要利用锦州义县地震站"十五"观测以来的数字化地电阻率整点值资料,对观测中常见的干扰因素进行了详细的识别与归类。研究结果表明:在地电阻率观测过程中存在雷电干扰、降雨干扰、观测系统故障、标定干扰等。This paper uses the Jinzhou Yixian seismic stations in the Tenth Five-Year observation since the digital resistivity value data, carried out a detailed identification and classification of common confounding factors in the observation. The results show that： in the interference of lightning, rain interference, observation of system failure, and calibration of interference in the observation process of the earth resistivity.

关 键 词：地电阻率 数字化 干扰因素
