摘　　要：对甘肃省内全部地电台站的地电阻率观测数据做了处理,筛选了6个观测台项十四个测向的电阻率观测结果作为研究对象,利用异常信息并结合甘肃及邻区发生的MS≥5.0级地震进行分析,其结果表明,地电临震异常特征明显,可以为地震预报提供相对定量的参考依据。The observation data of ground resistivity in fourteen determination directions of six stations in Gansu province were chosen to be dealt with in this paper. We analyzed the abnormal information before the earthquakes （Ms ≥5.0） in this region. The result shows that the characteristic of impending earthquake anomaly in ground resistivity is distinct and would be a relative quantitative index for earthquake prediction.
