摘　　要：应用地磁加卸载响应比方法对甘肃及周边地区2008—2014年地磁垂直分量Z的资料进行处理,结合实际震例分析,初步给出了适用于甘肃地区的地震分析预报异常形态特征的磁异常判别指标。By Using the geomagnetic load-unload response ratio method, the paper processes the data of geomagnetic vertical-component Z on Gansu and its surrounding seismic station from 2008 to 2015. The paper analyzes the applicability of the method combining with earthquake cases, and gives the anomaly index for earthquake prediction in Gansu area.
