摘　　要：本文研究了青藏块体近期地震活动两个显著的现象：中强地震自印度板块北部由南向北的地震扩展迁移现象和中强震空间分布的北东向地震条带及其相关现象，探讨了其形成的物理机制，分析了它们的发展趋势，据此对本区地震活动趋势进行了预测。In this paper, the two obvious phenomena of recent seismicity in the Qinghai-Tibet block are studied: the expand migration progress of moderate-strong earthquakes dynamic distribution from south to north originated in north part of India plate and northeast earthquakes stripe and correlative phenomena of moderate-strong earthquakes space distribution. Their physical mechanism and developing trend are analyzed; finally, based on all above, the seismicity trend in this region is predicted.
