摘　　要：比较了华北地区第3地震活动期和第4地震活动期地震活动时间进程特点,对华北地区中小地震G-R关系,青藏块体8级地震和华北地区7级地震的关系,日本海沟欧亚板块一侧8级地震和华北地区7级地震的关系以及郯庐带地震活动周期等方面进行了分析,认为华北地区未来3年甚至未来10年地震活动水平为6级,发生7级地震的可能性不大。The contrast of seismicity time process characteristics of No. 3 and No. 4 seismicity period in North China area is conducted. The authors analyzed the mid-small earthquakes G-R relation in North China area, the relationship between the M8 earthquakes in Qinghai-Tibet block , M8 on the Eurasian plate side of Japan Trench and M7 earthquakes in North China area, and the seismicity period in Tanlu belt. The result showed the seismicity level is M6 in future 3 years,even 10 years,and there is no possiblity to occur M7 earthquake.
