摘　　要：对南京地震台、新沂地震台和郫县地震台地电阻率观测资料变化特征及邻区4次M_S 5.0以上地震反应进行研究,发现:同一台站、不同测向地电阻率的测值大小可能存在较大差异,测值大的测道地电阻率年变化较规则,往往具有更强的映震能力。The earth resistivity observation data variation at Nanjing Seismic Station,Xinyi Seismic Station of Jiangsu Province and Pixian Seismic Station of Sichuan Province and the response to the 4 earthequakes of MS 5.0 in adjacent area are studied.draw conclusions：the earth re-sistivity measurements of different direction in the same stations may be larger differences, measured values year variation may be regular in larger measurement direction,also often have a stronger earthquake-reflecting ability in this direction.
