摘　　要：According to the 3-D velocity images of the crust and upper mantle in Xinjiang and its adjacent areas and the projective distribution of epicenters at different depths, this paper reveals the relationship between the velocity structure feature of the crust and upper mantle and seismicity in the studied areas, and also reveals the deep seismogenic environment in the Tianshan earthquake belt, intermediate and deep focus earthquake region in Hindu Kush, intermediate earthquake belts (regions) in west Kunlun and Kalakorum Mountain and so on different earthquake belts. The seismogenesis is also discussed.According to the 3-D velocity images of the crust and upper mantle in Xinjiang and its adjacent areas and the projective distribution of epicenters at different depths, this paper reveals the relationship between the velocity structure feature of the crust and upper mantle and seismicity in the studied areas, and also reveals the deep seismogenic environment in the Tianshan earthquake belt, intermediate and deep focus earthquake region in Hindu Kush, intermediate earthquake belts (regions) in west Kunlun and Kalakorum Mountain and so on different earthquake belts.
