摘　　要：通过统计分析北京地区历史地震时期的文献资料和现代地震的记录数据,基于历史地震和现代地震目录数据,运用ArcGIS、MapSIS等软件的分析结果,探究北京地区地震的时空分布特征。结果表明,北京地区在公元294年有地震史料记载以来至2020年的1727年内,共记载发生M≥3.0地震323次,主要分布在海淀区、昌平区、东城区等北京中部地质构造复杂地区;地震活动呈现一定的时间丛集性,在华北地区第三活跃期,北京地区地震活动水平较高,第四活跃期至今地震活动水平较弱。研究结果可为该区域地震活动性和危险性判定提供基础资料。Through the statistical analysis of the literature and Modern earthquakes record data during the historical earthquakes period in Beijing,based on the historical earthquakes and Modern earthquakes catalog data,and using the analysis results of ArcGIS,MapSIS and other software,this paper explores the temporal and spatial distribution characteristics of earthquakes in Beijing area.The results show that 323 earthquakes with M≥3.0 have been recorded in Beijing area in 1727 years from 294 to 2020,mainly distributed in Haidian District,Changping District,Dongcheng District and other areas with complex geological structures in central Beijing.The seismicity shows a certain time clustering.In the third active period of North China,the seismicity level in Beijing area is high,and the seismicity level since the fourth active period is weak.The research results can provide basic data for the determination of seismicity and risk in this area.
