摘　　要：本文选取了2010—2018年发生于安徽区域的MS2.0以上地震102次,使用单纯形定位法、Hyposat和Locsat定位程序分别配置华南模型与AH2015模型对其进行重定位。统计定位残差和定位深度,对比分析两种模型在安徽区域地震定位中的应用效果,同时对流动台反演深度进行精细分析。结果表明,使用AH2015模型在安徽区域的地震定位中残差更小,定位深度更符合真实深度,比华南模型更适用于安徽区域的地震定位研究。In this article,We selected 102 earthquakes above MS2.0 that occurred in Anhui region from 2010 to 2018,and re-located them using the simple locating method,Hyposat,and Locsat localization program with the South China model and AH2015 model respectively.The positioning residuals and depths of earthquakes are obtained and the application effects on earthquake location of the two models in Anhui region are analyzed and discussed.The inversion depths of mobile stations were used for fine analysis. The results show that the AH2015 model is more suitable than theSouth China model for seismic localization in Anhui area because the residuals are smaller and the localization depth ismore consistent with the real depth.
