本文基于山西带跨断层形变测量的全部历史资料,通过对1989年大同—阳高6.1级和1998年张北6.2级二次地震前断层形变群体性异常变化的分析,对山西带断层形变特征及与强震孕育发生之间可能存在的关系进行了系统研究,指出了断层形变在空间上和时间上存在的相对性特征,可供用震例中总结出的断层形变规律跟踪预测和研究未来震情的趋势时参考,同时对当前华北震情,特别是山西带震情的跟踪研究工作提出了建议和看法.%In this paper, the relationship between Shanxi seismic belt fault deformation features and strong earthquake preparation and occurrence is systematically analyzed and studied by analysing group fault anomalies before two earthquakes, 1989 M6. 1 Datong-Yanggao earthquake and 1998 M6. 2 Zhangbei earthquake, based the whole historical leveling data measured across faults on the belt. The relative characteristics of fault deformation in space and time are pointed out, and it can be referenced in tracking the development of the future earthquake situation for earthquake prediction and research works with experiences from earthquake samples. At the same time, suggestions and views on the current North China earthquake situation, especially for tracking the earthquake situation on the Shanxi seismic belt are put forward.
