摘　　要：本文利用新疆地区丰富的烈度等震线资料和1985年乌恰7.1级地震的余震、1997伽师4次6级地震和2005年乌什6.2级地震的加速度记录,对中国西部地震烈度和地震动反应谱衰减关系的适用性进行了分析。结果表明,中国西部地震动衰减关系对新疆地区的适用性较好。其中加速度反应谱的相关系数达到0.94。The paper studies the suitability analysis of ground motion attenuation relations of the West of China on the basis of the abundant data of earthquake intensity in the Xinjiang region and acceleration data from the aftershock of Wuqia M7. 1 earthquake in 1985, four events of Jiashi M6.0 earthquake in 1997, Wushi M6.2 earthquake in 2005. The result shows that there is a good suitability of ground motion attenuation relations in the West of China with the correlation of accelerating ground motion attenuation response spectrum reaching 0.94.
