摘　　要：分析了河北广平地磁台1982年至2006年地磁垂直分量日变幅逐日比值的高值异常与河北及邻区Ms≥5.0地震之间的关系,发现它们之间有较好的对应关系;同时给出了适用于广平地磁台的地震分析预报参数,并对其内检预报效能进行了评价,为今后广平台依磁报震提供了依据。Through analyzaing the relation between the high value anomalies of ratio daily amplitude variation, from 1982 to 2006, of vertical geomagnetic component of Guangping Geomagnetic Station of Hebei and earthquakes of Ms≥5.0 occurred in Hebei and its adjacent area, we found that those anomalies correspond with earthquakes quite well. This article provides the earthquake forecast parameter which is applicable to Guangping Geomagnetic Station, and assesses the station＇s predicting ability, thus providing basis for earthquake forecast according to geomagnetism at Guangping station.
