| 摘 要： | 为了探讨小区域内地震活动的时间规律。本文在中国大陆选择了11个地点分析其从远古至公元1990年间的破坏性地震（M≥4 3／4）的活动性。因而发现小区的地震活动规律主要表现于以大震为代表的地震活动分期上，破坏性地震的频率、集中程度与阶段性变化上，以及与所在地震区地震活动期的关系上，不同小区的地震活动特征有共性，有类型区别，更有各自的特殊性。

| Abstract: | To search for the time regularity of seismic activity in a small region, in this paper we select 11 regions to analyze activity of destructive earthquakes ( M>43/4) from the remote antiquity to A.D. 1900. As a result, we found that the time regularity is maily expressed as the strong earthquake periods and episodes, frequency and feature changes in different phases of the activity, and the relation with the strong earthquake periods in the seismic regions, in which the small regions are involved. The feature of seismic activity in different small regions has generality, distinction in types and respective particularity. |
