摘　　要：190 0年以来 ,中国大陆经历了 5个地震活跃期和 4个地震平静期 ,活跃期中Ms≥ 6 0地震为线性分布和块状分布 ,平静期中Ms≥ 6 0地震为线性分布。线性分布和块状分布形象地展示了每个活动期中作用力的传递方向和途径 ,以及地震活动区域所受到的严格约束。因此 。Continental China has experienced the 5 seismically active periods and 4 quiet periods since 1900 During the active periods, the M≥6 0 earthquakes took place in linear and block distribution, while during the quiet period, the earthquakes occurred in linear distribution The linear and block distribution of the earthquakes vividly displays transmission direction and path of force and strict restriction of seismicity regions in each active period, which provides a new clue for studying seismic dynamics and seismicity regions in continental China

关 键 词：中国大陆 地震活动图像 线性分布 地震动力学
