摘　　要：利用山东及近邻区34个地震的70条等震线数据,通过最小二乘法回归分析得到了山东及近邻区地震烈度衰减关系;同时根据地形与地质构造特征将山东及近邻区分为土层覆盖区和基岩出露区,分别拟合出了各自的地震烈度衰减关系。The formula of seismic intensity attenuation for Shangdong and its adjacent areas is fitted by using 70 isoseismal lines from 34 earthquakes in this region. Meanwhile based on the difference of land- form and geological structure characteristic, the region is divided into soil covered area and bedrock exposed area, the individual formula of seismic intensity attenuation for both areas are fitted also.
