摘　　要：数字地震记录携带大量的地壳运动信息,包含发震时的震源信息,射线传播过程中的介质信息,以及接受信号的台站场地相应等诸多地震动态信息,本文通过处理和分析数字地震记录,提取地震的震源参数,从而分析出宁夏地震区地震射线传播过程中的介质特性、台站的场地响应,为地震预测预报和地震危险性分析提供依据的目的。Digital seismic records carry a large amount of crustal movement information,including the source information at the time of the earthquake,the medium information in the ray propagation process,and the corresponding seismic dynamic information of the station receiving the signal.This article deals with and analyzes the digital earthquake.Record and extract the source parameters of the earthquake,analyze the medium characteristics during the seismic ray propagation process,and the site response of the station,so as to better provide a basis for earthquake prediction and earthquake risk analysis.
