摘　　要：河北2015地壳速度模型是根据河北省2009—2014年数字化震相资料以及河北省地质情况建立的区域地壳双层速度模型(简称2015模型)。为提高地震速报及编目质量,在ISDP和MSDP软件中应用2015模型、华南模型、华北模型,并通过单纯型、hyposat、盖格法对2009—2016年90条较显著地震进行定位分析。从定位残差、震中偏差、震级偏差3方面分析对比各模型,结果表明,2015模型与其他2个模型在各方面相差不大,符合地震速报及编目工作要求,也更适合河北区域地震的定位分析,为2015模型在河北测震台网的实际应用提供依据。Hebei 2015 crustal velocity model（hereinafter referred to as the new model）is a regional crustal double-layer velocity model,which was established based on the digital seismic data of Hebei province from 2009 to 2014 and geological conditions of Hebei province.To improve the quality of seismic quick report and cataloging,the simplex,Hyposat and Geiger methods were used to locate 90 significant earthquakes from 2009 to 2016 in ISDP and MSDP with the new model and old model.Through analyzing the location residuals,epicenter deviation and magnitude,it revealed that the location result from the new model is not far from the other two models.The differences between of them are meeting the specification of earthquake quick report and cataloging,and also more suitable for the location analysis of Hebei regional earthquake.All of the above works provided the reliability for the practical application of the new model in Hebei province.
