中国大陆强震构造环境统计分析

基于近10年活断层研究资料和第四代全国抗震设防区划图的成果，对中国大陆有史以来6级以上强震的构造环境进行了统计研究。探讨了各地震区强震的震源区构造类型、发震构造活动方式，分析了各类地震的地表破裂带长度和极震区长轴方位特征，以及强震震源区的区域构造应力场、地球物理场(包括重力异常、壳幔高导层异常、大地热流密度)和现代地壳垂直形变场等特征。

Statistical Seismotectonics of Strong Earthquakes in Chinese Mainland

Based on study of active faults in the recent years and the achievements of the seismic regionalization of the fourth generation in China, this paper gives some seismotectonic statistics of strong historic earthquakes in Chinese mainland with magnitude larger than 6.0, which include the tectonic patterns of epicentral areas and the displacement patterns of seismic faults of strong earthquake in each seismic region, characteristics of the surface fracture length and major axis's azimuth of epicentral areas of every kind of earthquake, as well as features of tectonic stress field, geophysical field (including gravity abnormality, high electric conductive layer in crust or mantle, and geothermal density) and modern vertical displacement field of crust.
