【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。更多还原

【Abstract】 Based on the earthquake catalog with magnitude over 5.0 and reports of earthquake disaster evaluation provided by provincial earthquake administration,the major data and characteristics 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.更多还原
