摘　　要：利用西南震害资料,对西南省域(云南、四川、重庆、西藏、贵州)在一定时空尺度上M≥5.0历史地震事件活动水平及震害特征进行系统分析,找出地震灾害(包括人员伤亡、经济损失、次生灾害等)的时间发展特征、空间分布特征和强度分级特征;研究地震灾害与西南区域人口分布、经济水平、地形地貌、人文因素之间的耦合关系,为进一步减轻、减少地震灾害应急处置的不确定性和风险性提供有效建议。Based on the earthquake catalog with magnitude over 5 .0 and reports of earthquake disas-ter evaluation provided by provincial earthquake administration,the major data and charac-teristics of earthquake disasters in southwest China are summarized,the spatial-temporal characteristics and strength grade characteristics were analyzed.The research indicated that earthquake disasters have a coupling relationship with population distribution,economic level,topography and geomorphology and human factors in southwest of China. Some summarizes for the governments to reconstruct and reduce earthquake disaster are proposed.
