In this study, we analyze the distribution characteristics of Q value of seismic coda in Ningxia and neighboring areas by considering 665 digital wave data points of earthquakes with M_L≥2.0 from January, 2008 to December, 2013 recorded by the Ningxia Earthquake Network using the Aki model. The selected waveform records are clear, and the noise levels satisfy the requirements. By comparing the Q values of seismic coda in each area of the Ningxia Province and its adjacent region with existing results, the distribution characteristics of Q value of seismic coda are obtained. The results show that the Q value of seismic coda is higher in the north than in the south. The Q values of seismic coda in Wuzhong and Lingwu areas are relatively high, corresponding to the high-speed zone. The Q values of seismic coda in the region southwest of Alashan Zuoqi and those in Zhongwei, Haiyuan, and their adjacent regions are relatively low. These results may be associated with the high temperatures and heat-flow values in the deep crust of those areas.
