根据古地震探槽剖面及断坎年代资料，综合分析了北祁连山东段活动断裂带的古地震活动特征。沿断裂带的古地震具有非均匀性活动的特点，表现为活动期次的差异性、空间上的分段性和各段时间上的准周期性。
Based on the data of the paleoseismic trenches and the data from the fault ridge and canyon, the characteristics of paleoearthquakes in the active fault zone in the eastern part of the northern Qilian Mountains are analyzed synthetically. Paleo-earthquake along the fault zone has the characteristics of inhomogeneous activity, which is characterized by the difference of activity period, the fragmentation of space and the quasi-periodicity of each period of time.
