| 摘 要： | 通过提出时空比例系数fts，从而引入时空距离这一概念，并因此将地震事件的时空属性耦合在一起．借助时空距离概念，对华北地区公元1500年以来的强震对进行了时空相关性分析．结果表明，当fts取10km/a时，强震对沿时空距离轴大致分为两类:时空距离小于140km的强震对彼此具有一定成因关系；而相距280km以上的强震则为互相独立的地震事件．该特征可为华北地区强震迁移规律的总结以及趋势预测提供参考．

| Abstract: | In order to unify the time and the space attributes into temporal-spatial distance, the temporal-spatial proportional coefficient f ts is proposed in this paper. In accordance with the new distance concept, the temporal-spatial correlativity within temporal doublets of strong earthquakes in North China and its vicinity since AD 1500 has been analyzed. The computation results indicate that doublets of strong earthquake can be divided into two groups when f ts is endowed with 10 km/a in the new distance formula. The temporal-spatial distance between two points of doublet generally cannot exceed 140 km when two strong quakes in doublet have some causative relation. And those doublets whose temporal-spatial distance exceed 280 km are probably independent seismic events in doublets. This character can be the reference to the migration law summarization and trend prediction. |
