摘　　要：通过分析云南省的历史地震灾害造成的生命损失数据,表明20世纪以来云南省的地震生命损失具有显著的区域性差异。以红河断裂为界,红河断裂带上及其以东的滇西北、滇中和滇东北地区,其地震生命损失的严重程度明显高于红河断裂以西的滇西和滇西南地区。同时,从云南省的人口密度、民居建筑区域特点和地质地貌条件等方面,分析了云南省地震生命损失区域性差异可能的自然环境和社会影响因素。On the basis of analysis on the data of life loss from the earthquakes in Yunnan province since 1900, we found that there exists remarkable difference from region to region. The severity degree of the life loss from earthquake is significantly higher in the west-north, central and east-north Yunnan, east to the Honghc fault than that in thc west and west-south Yunnan, west to the Honghe fault. Our results suggest that the factors of population density, local style of civil houses and geological land feature arc probably attributed to the regional difference of life loss from earthquakes in Yunnan province.
