摘　　要：通过对中国大陆及邻区1900年以来7级以上地震活动轮回的划分、各轮回活跃幕和平静幕内7级以上地震活动特征的分析得出了未来中国大陆及邻区7级以上地震活动的水平和可能地点,并分析了太阳黑子活动周期曲线和中国大陆及邻区7.1级以上地震活跃幕的关系、全球7级以上地震活动对中国大陆的影响等得出了未来20年中国大陆及邻区发生8级以上地震的可能性不大,7级以上地震活动水平偏低的结论。Through the division of the cycle of seismic activity of earthquakes with MS ≥ 7.0 and analysis of the seismic activity characteristics of earthquakes with MS ≥ 7.0 in each cycle in China mainland and adjacent region since 1900, the level and possible location of seismic activity of earthquakes with MS ≥ 7.0 in China mainland and adjacent areas in the future are obtained. It also analyzes the relationship between the activity cycle curve of sunspot and the seismicity in China mainland and neighboring areas, and the influence of seismic activity on China mainland. It is concluded that there is little possibility of an earthquake with MS ≥ 8.0 and the level of seismic activity of earth-quakes with MS ≥ 7.0 is low.
