摘　　要：选取广东省数字化地磁观测以来的地磁资料和一定震中距的显著地震事件,计算地震前1~2年的地磁垂直分量加卸载响应比,结果显示,显著地震前1个月至1年不等,地磁加卸载响应比值有明显超经验阈值2.8的现象。Geomagnetic data since the digital geomagnetic observation in Guangdong Province and the significant earthquake events with a certain epicenter distance are selected to calculate the load-unload response ratio of the geomagnetic vertical component 1-2 years before the an earthquake.Results show that the ratio of geomagnetic load-unload response exceeds obviously the empirical threshold of 2.8 about one month or one year before a significant earthquake.
