摘　　要：2015年10月26日,阿富汗兴都库什地区发生7.8级地震。中国国家强震动台网中心收到新疆自治区地震局40组强震动记录事件,对此地震进行反应谱和傅里叶谱分析,得出峰值加速度图和仪器烈度图,得到震中距536.6 km的布拉克苏地震台获得最大地震动峰值加速度为20.3 cm/s^2,得到的仪器烈度值最大为5.3度,最近的469.2 km的新疆吉根地震台仪器烈度为2.4度,可以体现出强震动台网建设的作用和效果。M7. 8 earthquake occurred on October 26,2015 in Afghan Hindukush region. China national strong motion network center received 40 groups of strong motion records events recorded by Earthquake Adminisration of Xinjiang Autonomus Region. This earthquake response spectrum and the Fourier spectrum are analyzed and got the graph diagram and instrumental intensity of peak ground acceleration. The epicenter distance of Braqus Sudeten seismic station is 536. 6 km and its maximum peak ground acceleration is 20. 3 cm/s2,the maximum value of instrumental seismic intensity is 5. 3 degree. The epicenter distance of Xinjiang Jigen seismic station is 469. 2 km and its instrumental intensity is 2. 4 degree. The function of these stations can reflect the strong motion network construction effect.
