摘　　要：研究华北块体1970年以来的13次典型6级以上地震,通过组合地震显著增强异常指标的预测时间、预测范围等参数,使用Molchan、 R值等方法进行全时空扫描检测效能评估,最终验证了地震显著增强异常地震预测指标在华北块体的适用性和最佳预报参数,为使用该方法的震情跟踪工作提供切实依据。Research 13 typical earthquakes of magnitude 6 or higher in the North China block since 1970. Evaluating the effectiveness of full-time sweep detection of earthquake significantly enhanced anomaly index using Molchan and R values, research on the optimum prediction time and space parameters. Finally, the applicability of earthquake significantly enhanced anomaly index in North China Block is verified, it provides a practical basis for earthquake situation tracking using this method.
