Abstract:: The rapid assessment of the number and distribution of victims trapped in rubbles and an emergency rescue are key to reducing casualties after an earthquake.The models of population spatialization are established based on building functions,structure of indoor people,and the rate of indoor people.Using the functional units of villages and urban ditricts in Dali City as evaluation units,we assessed the risk of the trapped victims.The results show that the high-risk period of earthquake-caused burial of people in a day falls between 19 p.m.and 7 a.m. .Xizhou Ancient Town has the highest risk when hit by Intensity Ⅷ.Xiaguan Town faces the highest risk of personnel burial when subjected to the intensity exceeding VIII.The following villages have a high risk of earthquake-caused burial of people.They are Manjiang,Jinxing,Dazhantun,etc.in Dali City,Caicun,Xiangyang,Shuanglang,etc.along the Erhai Lake,and the ancient villages at the foot of the Cangshan Mountains including Jiangxi,Shanghe,Zhoucheng,etc. .These places need to be given special attention when earthquakes occur.
