介绍了中国及邻区地震目录数据库的开发状况 ,从历史强震、近代强震及强震震源深度等几个方面 ,结合我国及邻区板块构造以及应力状态、壳幔结构的东西部差异对我国强震的空间格局进行了较为系统的分析 .公元 190 0年以前我国华北地区的强震呈现出大梯形格局 ,而公元 190 0年之后我国强震则以西部的巨大扇形为主要特征 ,其中震源深度最深的区域分别位于大扇形的 2个顶点处 ,即兴都库什—帕米尔以及缅印交界地区 .就我国强震所特有的空间分布格局对我国强震的线性以及区域性迁移模式进行了总结和分析 ,其中线性迁移模式又可细分为前进跳跃式和钟摆式 .对文中涉及的强震迁移机制分别利用断层破裂、弹簧 -滑块、壳幔的结构性差异以及它们之间的相对运动等模型进行了初步的解释 .
This paper introduces the development of the earthquake catalog database in China and its neighboring regions. Based on the historical strong earthquakes, the recent strong earthquakes and focal depths of the strong earthquakes, this paper combines the plate tectonics in China and its adjacent areas with the stress state and the differences between east and west of the crust-mantle structure The spatial pattern of the strong earthquakes in China was systematically analyzed. Before 190 AD, the strong earthquakes in North China presented a large trapezoidal pattern, while the strong earthquakes in China after1900 AD were dominated by the huge fan in the west, of which The regions with the deepest source depths are located at the two vertexes of a large fan, namely Hindu-Kush-Pamir and the Burma-India Boundary Zone. The linear and regional migration patterns of strong earthquakes in China are studied based on the spatial distribution pattern unique to China’s strong earthquakes The linear migration model can be subdivided into forward leaping and pendulum.The mechanisms of strong earthquakes involved in the paper use the structural differences of fault rupture, spring-slider and mantle, and the difference between them Relative motion model for a preliminary explanation.
