摘　　要：发生在台湾省车笼埔断层上的集集地震造成了大量人员伤亡。本文搜集了该地震高烈度区的村里级行政单元的死亡率数据,并分析了城市型、乡镇型和农村型居民地的死亡率与地震烈度的关系。表明城市型和乡镇型平均死亡率差别不大,农村型则明显较高。对死亡率与地表破裂带、高烈度分布区和局部场地条件的关系等进行了分析,在此基础上,显示了死亡率随距离分布在断层两侧的不对称性。上述结果加深了对集集地震死亡率分布及其成因的认识,对评估未来地震人员死亡有重要意义。Chi-Chi Earthquake,occurred on the Chelungpu fault,caused many people deaths and injuries.This paper collected the casualty data in village and hamlet administrative units in the high intensity area,analyzed the relation between earthquake intensity and people death rate responding to three types of residential areas： city,town and village.It is obvious that the death rates in city and town type＇s areas are almost distributed in the same range while the death rates in village type areas are higher than them.The analysis of the relation between death rate and the factors such as the ground surface rupture distribution,the high intensity region and site conditions in local areas shown that the death rates with distance are asymmetrically distributed on both sides of the fault.These results make deeper cognition of the death rate distribution of Chi-Chi earthquake,and are significant for evaluation of casualty in the forthcoming earthquakes.
