摘　　要：根据历史地震活动资料 ,分析研究了中国东北深震区的地震活动与中国大陆地区地震活动的相关特征 .结果表明 ,中国大陆地震活动高潮期的地震活动水平和6 .5级以上深震的发生有密切关系 .深震发生后 3年以内 ,中国大陆强震活动明显增强 .这些强震沿北纬 40°线和南北地震带呈优势分布 .Based on the historical seismicity data,correlation between seismic activity of deep seismic area in northeastern China and that of Chinese continent is analyzed and studied. The result shows that seismic activity in seismicity peak period of Chinese continent is related to M S≥6.5 deep focus earthquakes. During three years after deep focus earthquake occurred ,seismicity of Chinese continent obviously strengthened and strong earthquakes may occur along 40°N and north south seismic zone.
