摘　　要：介绍了 2 0 0 0年 6月 6日景泰MS5.9地震后 ,在该区进行的大地电磁跟踪监测结果 .在监测时段内所观测的视电阻率随时间没有大的变化 ,在观测误差范围内有较好的可重复性 .据此判定震后一段时间内发生较大地震的可能性不大 .The magnetotelluric(MT) monitoring results for seismicity after the Jingtai M S5.9 on June 6,2000,Gansu province are introduced.Changes of apparent resistivity with time in the monitoring period are analyzed.It is believed that it is improbable that stonger earthquakes should occur after the Jingtai earthquake according to smaller variations and repeated character in range of error of observed apparent resistivity with time. The judgement result is identical with reality.
