| 摘 要： | 采用内蒙古测震台网2009—2016年记录的内蒙古东部地区131个地震资料，使用速度拟合、分区扫面、折合走时方法，反演得到该区域速度模型：v1=6.10 km/s、vPb=6.72 km/s、vn=8.05 km/s、H1=23 km和H2=16 km。东部模型检验结果显示，定位残差均值较华南模型和2015内蒙最优模型有明显的降低，且更加均匀稳定；东部模型与编目定位震中差较华南与编目、2015内蒙最优模型与编目和华南与编目震中差均值降低1 km左右。可见，东部模型更适合内蒙古东部地区。

| Abstract: | Based on the data of 131 seismic data recorded in the eastern part of Inner Mongolia from 2009 to 2016, the velocity model of the eastern part of Inner Mongolia was obtained by using the method of "velocity fitting, zoning and folding". v1=6.10 km/s, vPb=6.72 km/s, vn=8.05 km/s, H1=23 m and H2=16 km. The results of the eastern model show that the mean of the residuals in the eastern model is significantly lower than that of the South China model and the 2015 Inner Mongolia optimal model, and the residuals are more uniform and stable. The epicenter difference of "East model-catalog" is less 1 km than those of "South China-catalog", "2015 Inner Mongolia optimal model-catalog" and "South China-catalog". It can be seen that the eastern model more suitable for eastern region of Inner Mongolia. |
