中文摘要：
通过数理统计和横向对比定量、定性地分析昭通地震灾害的区域性特征,并从地理环境因素进行诠释.统计结果表明,昭通地震人员死亡、受灾人口、房屋破坏总面积、直接经济损失与震级总体呈指数关系;相同地震能量条件下,地震灾害直接经济损失随年份呈线性增长趋势.从横向对比看,昭通具有典型的小震大灾特征,同等条件下,昭通地震灾害损失是云南其他地区的2～5倍.人口基数大、人口密度高、社会财富总量大但社会经济发展水平低下和房屋抗震性能弱等是造成昭通地震灾害损失大的主要原因.地形起伏大、地表岩石破碎等原因使得昭通地震崩滑次生灾害严重.
英文摘要：
We analyze quantitatively and qualitatively the regional features of the earthquake disaster in Zhaotong area by mathematical statistics and horizontal comparison.By mathematical statistics,we find that the casualties,the affected population,the total area of the damaged buildings,and the direct economic loss are generally in an exponential relation with the earthquake magnitude.In the condition of the same earthquake energy,the direct economic losses caused by the earthquakes have a linear increase relation with year.By horizontal comparison,we find that the earthquake disaster in Zhaotong area are featured as ‘ small earthquake causing serious disaster’,for example,on the same condition,the disaster loss in Zhaotong may be 2 to 5 times of those in other earthquake disaster areas in Yunnan.The factors such as large population base,high population density,large amount of social wealth,low level of socio-economic development,and weak seismic performance of buildings,etc.,mainly caused serious disaster loss.In Zhaotong area,the factors such as the large-scale topographies,broken surface rock etc.caused serious secondary disasters such as collapse and landslide.
