摘　　要：从构造体制的转化出发探讨了处于北秦岭加里东造山带的天水东部地区地壳构造演化史。研究区地壳构造演化大致经历了８个大的构造旋回。On the based on the change of tectonic systems of organization, the history of crust tectonic evolution in the east area of Tianshui situated in the north Qinling Caledonides was discussed. The orust tectonic evolution in the research area could been divided into 8 large tectonic cycles, 7 times change of tectoni systems of organization, and subdivided it into tectonic evolution deformation series of 15 generations.
