摘要： 对大华北地区地震资料相对可靠的20世纪以来第三、第四活动期的地震活动做了分析,发现前后二地震活动期有着不同的空间分布类型, 但彼此联系密切又相对完整。通过对比研究发现, 二个活动期地震活动的主体区域基本上互不重复, 地震活动有等间距发生的特征, 认为这一现象对于分析今后地震活动的地点具有重要意义。

Abstract: In this paper, the earthquake activity of the 3rd and 4th active periods in North China region since the 20th century has been comprehensively analyzed. The authors have found that there are different space distributionty pes of earthquake activity during the previous and following active periods, but the two earthquake activity periods are closely connected each other and are independent. By compari son, the main body areas of the earthquake activities in the two earthquake activity periods show the characteristics without repeatability basically and the same intervals between the earthquakes. The authors think that this feature will be important to study and analyze the location of earthquakes in the future.

Key words: North China region, Seismicity feature, Spatial evolution
