| 摘 要： | 本文主要从祁连山中东段主要活动断裂带全新世以来古地震活动以及历史地震和现代地震的复发间隔入手，通过对强震复发间隔与平均复发间隔的比值(T/Ta)的数学处理，建立了区域强震复发所遵循的概率模型，并对未来强震的复发可能性和强震发生地点进行预测。结果表明，本地区未来最有可能的强震发生地点是老虎山-毛毛山断裂带的毛毛山-金强河段。

| Abstract: | In this paper, starting with palaeoearthquakes and historic and recent earthquakes recurrence intervals for main active fault zones in middle-eastern segment of Qilian Mt. since Holocene, by calculating the ratios of recurrence interval of strong earthquake to that of average(T/T_a), the strong earthquake recurrence probability model is established, and the model has applied to predict possibility and sites of strong earthquake. It reveals that, in this rigion the possible site where strong earthquake maybe occurs in future is on Maomaoshan-Jinqiang segment of Laohushan-Maomaoshan Fault. |
