摘　　要：利用20世纪华南地区的48次中强地震事件的96条等震线数据,拟合了该地区地震烈度衰减关系。与以往的地震烈度衰减关系相比,在计算中强地震烈度时,精度上得到了相应的提高。充分反映了华南地区地震震级小,烈度相对高的特点。Based on the data of 96 isoseismal lines of 48 earthquakes in South China,seismic intensity attenuation relationship in this region was fitted.Compared with the past model,the calculation accuracy of moderate earthquakes intensity was improved by using the method in this paper.The model fully reflected the fact of relative high intensities generated by relative small earthquakes in South China.
