中文摘要：

由1876个远震三分量P波地震图组成的数据集,取自布置于鄂尔多斯—太行山一线的宽频带流动台站。通过阵列反卷积方法,得到地下界面响应的接收函数,并通过共转换点偏移叠加得到地下结构的图像。图像显示,从鄂尔多斯至渤海湾盆地地壳厚度总体上逐渐变薄,Moho面总体呈小角度向西倾斜。鄂尔多斯块体中部地壳最厚,达到52km,向东到鄂尔多斯边缘,地壳厚度减小至43km。太行山至渤海湾盆地地壳厚度从45km减小至37km。山西地堑下方Moho面上隆,和两边的Moho面相比,抬升8～10km,且其Moho面的上隆和新生代地堑的凹陷呈镜像关系。

英文摘要：

A data set of 1876 three-component,P wave seismograms from 22 stations deployed at Ordos and Taihang mountains was collected to investigate crust and upper mantle structure of that area. By using the array deconvolution method,the vertical,radial,and tangential receiver functions of all events are obtained. All radial receiver functions are then migrated to produce a seismic image. The image shows that from Ordos to Bohai Bay basin,the crust becomes thinner from about 52 km to 37 km,and the Moho generally dips to the west at a small angle. In central part of Ordos basin,the crust is thickest,reaching 52 km;at the eastern edge of Ordos,the thickness decreases to 43 km. From Taihang Mountain to Bohai Bay basin,the thickness of the crust changes from 45 km to 37 km. Under the Shanxi Graben,the Moho suddenly uplifts by approximately 8-10 km in comparison to that of both sides,and the rise of the Moho and the depression of the surface show a mirror-image relationship.
