摘　　要：利用海南岛及邻区17次地震的42条等震线数据,通过最小二乘法回归分析得到海南岛及邻区地震烈度衰减关系;这些资料符合海南岛历史和近代地震震害分布的地域性特点,可进一步应用于地震安全性评价、震害预测和快速评估损失等工作。The formula of seismic intensity attenuation for Hainan island and its adjacent areas is obtained by least squares regression analysis using 42 isoseismal line from 17 earthquakes in this region.The result shows that this relation represents the features of damage distribution of historical and modern earthquakes in the areas,and can be applied to seismic safety evaluation,earthquake damage prediction and fast loss assessment.
