摘　　要：2019年1月7日,河北邯郸地区广平台、涉县台地磁FHD观测仪Z分量数据同时出现了加卸载响应比高值变化。通过对观测系统检测、测区环境调查、空间影响分析、与台站其他观测进行对比及以往震例讨论等,认为该变化可能为一次地磁局部地球物理异常事件。It appears high value anomalies of geomagnetic Z component for loading and unloading response ratio at Guangping and Shexian seismic stations in Hebei Province on Jan.7,2019.By the way of observation system detection,environmental of the survey area,space events judgment,summary of earthquake cases in other stations and so on,the comprehensive analysis indicates it’s more likely that the change is geomagnetic anomalies.
