摘　　要：在合理分区、收集整理陕西及邻近地区1900年以来5级以上地震资料的基础上,利用烈度衰减的椭圆模型,采用多元稳健线性回归方法,分区统计计算得到陕西陕南、关中和陕北地区的烈度衰减关系,并对结果进行了分析讨论。Based on reasonable zoning and data of earthquakes with magnitude equal to or greater than 5 since1900s in Shaanxi province and its neighboring regions,using ellipse intensity attenuation model and multiple stablelinear regression method,intensity attenuation relations among southern Shaanxi,Guanzhong region and northernShaanxi are obtained by divisional statistics and calculation and the results are analyzed and discussed.
