摘　　要：根据新沂台前兆资料 ,运用加卸载响应比、差分法对地磁场Z分量进行分析 ;运用滑动平均对短水准资料进行分析 ;运用速率法对视电阻率进行分析 ;结果表明 :在苍山地震前 ,新沂台前兆资料具有良好的中、短期异常 ,并有进入临震的异常标志。Introduced the base of Xinyi station.By usingload unload response method,difference method,sliding average and velocity.we analysed the changes in the geomagnetic vertical component Z,short levelling and resistivity in Xinyi station.It is revealed that there are middle short obvious anomaly and anomaly mark of impending erathquke in Xinyi station.It shows this earthquke could be predicted by using precursory records in Xinyi station.

关 键 词：加卸载响应比 速率法 视电阻率 苍山地震 地震前兆异常 差分法 地磁场
