摘　　要：对福建及邻近地区地震烈度资料进行等效处理、近远场补点、数据加权处理,改进衰减模型和统计方法,加强了对大震近、远场的控制,建立了适合本地区的地震烈度衰减关系,并对比分析了Ra和Rb取值、补点和加权对烈度衰减关系的影响。Based on the seismic the near-far field and data data of Fujian and its adjacent areas through the equivalent process, auxiliary point of weighting, the statistic method and the attenuation model has been improved and the near-far field control to large earthquake has been strengthened. An intensity attenuation relation suitable to the areas has been established, and further the influence of Ra and Rb, auxiliary point and weighting to the intensity attenuation relation is contrasted and analyzed.
