摘　　要：研究认为：虽然此次南黄海６．１级地震距江苏地磁台网较远，但南通台的Ｆ２１测值在震前仍有历时约２２个月的信度较高的异常，同时存在幅相法异常。Although the geomagnetic network of Jiangsu province is far from the epicentre of the South Yellow Sea earthquake of M s 6.1, there was F 21 value anomaly of higher credibility of 22 month's duration in Nantong station, and there was the anomaly of amplitude phase method, it is very difficult to accurately predict three elements of earthquake using the geomagnetic data.
