| 摘 要： | 应用宁夏9个台站1986年后记录的宁夏及邻区132次地震的200条DD－1仪模拟记录，对宁夏及邻区的分区尾波Q值进行了研究，结果表明，分区尾波Q值主要与地质构造有关。Q值相对较低的区域为吉兰泰盆地，银川盆地南段的吴忠，灵武，阿拉善左旗西南，中卫至海原之间，吴忠，灵武至盐池之间；相对较高的区域为乌海及附近，贺兰山，永宁至大武口之间。

| Abstract: | simulation recordings, which were 132 earthquakes, occurred in Ningxia and its adjacent region and were recorded on 9 seismographs of DD-1 type in Ningxia, have been studied. The results indicated that Q values in different areas mainly related with geologic tectonic.The areas where Q value are relatively lower are Jilantai Basin,Wuzhong and Lingwu in south section of Yinchuan basin,the southwest part of Alashanzuoqi,Zhongwei to Haiyuan, and Wuzhong and Lingwu to Yanchi.The areas where Q value are relatively higher are Wuhai and neighboring region, the Helan Mountain, and Yongning to Dawukou. |
