摘　　要：中国台湾地区和大陆西北地区都是破坏性地震活动发生较为频繁的地区。应用数理统计的方法对这两个地区100年来破坏性地震活动的对应关系进行探讨,当台湾地区发生6级以上地震活动后两年内,大陆西北也发生6级以上地震的概率为95.08%;两地7级以上地震活动时间间隔的置信度为90%的区间估计都为2～4年;通过对两地7级以上地震活动时间间隔的相关性分析,可以看出无显著性差异。Strong earthquakes often occurred in Taiwan and northweatern regions in China.The corresponding and symmetry relation of the seismicity in recent 100 years between two regions is discussed using mathematical statistics method.The results show that the probability of MS≥6.0 earthquakes in the northwestern region is 95.08% in two years after MS≥6.0 earthquakes in Taiwan region.The time interval among MS≥7.0 earthquakes with 90% confidence degree were 2~4 years for both regions.There is no obvious difference in distribution of time interval of MS≥7.0 earthquakes for two regions by analyzing corresponding relationship between seismicity of two regions.
