| 摘 要： | 通过对首都圈地区不同时期的18条深地震测深(DSS)测线资料的重新统一处理，形成采样网格密度为025°×025°×（2～5）km的速度网格化数字地壳；通过对三维数据的可视化，得到了首都圈地壳不同走向、不同圈层的截面图像；从不同的视角、不同的方面探讨了控制首都圈地壳的北部燕山隆起、西南部太行隆起和东南部裂陷盆地等三大地质单元的构造特征以及接触带张家口-渤海断陷带的构造性质，进一步研究首都圈地壳内部结构构造与灾害性地震的孕发机制的关系.

| Abstract: | After unified reprocessing of the 18 DSS profile data that are got in various periods in the Capital area, a digital crust model of velocity grid is obtained with sampling density 025°×025°×（2～5）km. Through 3 D data visualization, images of slice sections in different strikes and at depths are produced. Based on these images, the tectonic characteristics of the three main geological units, which control the crust in the Capital area including the Yanshan uplift in north, the Taihang uplift in southwest and the rift depression basin in southeast, and the tectonic features of the contact zone——the Zhangjiakou Bohai Sea seismic zone are studied from various aspects. Furthmore, the relation between the inner structure of the crust in the Capital area and the generation of catastrophic earthquakes is studied. |
