摘要
本文系统清理了大华北块体有连续强震记录的１２９１年以来的强震活动特征，从大地震的阶段性孕育过程所呈现的有序活动，总结了一些有某种前兆意义的几种异常图象，通过对华北地区大震震例清理，筛选出８个中长期异常图象判据，并进而讨论了汾渭地震带等地的强震趋势。
The paper systematically arranges the strong seismisity characteristics of North China since 1291,andsummarizes some anomalous pattern with certain precursor implication based on the order activity in the seis-mogenic process of the large earthquake,Through the arrangement of the earthquake examples in North Chi-na, screens out 8 critera of long-and medium-term anomalous pattern, and discusses the strong earthquaketrend in Fen-Wei seismic zone.
