摘　　要：应用江苏地磁台网Z分量21点观测值,初步研究了其空间相关性及与江苏地区地震的对应关系,发现在研究的12年内,共出现了符合判据标准的异常8次,其中在其后7个月内检报对5个MS50以上地震,而其间应报地震6个,虚报1次,漏报1次。This paper studys the relation between the anomaly of spatial correlation of geomagnetic Z 21 value and the earthquake in Jiangsu area,eight anomalies in Jiangsu geomagnetic stations have been obtained in twelve years,five of which respond to M S>5 0 earthquake seven months after the earthquake,six earthquakes with M S>5 0 should be predicted,one is false prediction and one is missed prediction.
