摘　　要：根据大同地震遥测台网１９８９年—１９９４年记录的地震资料，采用代数重建法联合反演了大同—阳高６．１级地震震源区及其周围地区（φＮ３９．５°～φＮ４０．４°，λＥ１１２．５°～λＥ１１４．４°）地壳的三维Ｐ波速度结构。Based on the local earthquake data recorded by the Datong telemetric seismic network from 1989 to 1994,the 3 dimensional P wave velocity structure of the focal region and its nearby region of the Datong Yanggao M 6 1 earthquake(φ N39 5°～φ N40 4°,λ E112 5°～λ E114 4°)was inversed by thd algebraic reconstruction method,and the significance for revealing the seismogenic condition of the focal region was suggested.
