摘要
详细讨论了2003年以来宁夏及邻区弹性衰减系数Q值，对其进行分时段计算和讨论，得到宁夏及邻区2003-2005年、2003年、2004年和2005年地震的非弹性衰减系数Q值随频率f的关系，分别为Q（f）=553.8f^0.292，Q（f）=615.2f^0.274，Q（f）=683.2f^0.233，Q（f）=728.6f^0.230，得到祁连山中东段的非弹性衰减系数Q值随频率f的关系为Q（f）=671.6f^0.307。
The elastic attenuation Q value in Ningxia and its adjacent region was discussed in detail and calculated in different period. The inversion results indicate that the frequency-dependent of inelastic attenuation Q value in 2003-2005、2003、2004 and 2005 is estimated as： Q（f）=553.8 f^0.292、Q（f）=615.2f^0.274、Q（f）=683.2f^0.233、Q（f）=728.6f^0.230 and the frequency-dependent of inelastic attenuation Q value in the middle-east segment of Qilianshan is estimated as： Q（J）=671.6f^0.307.
