摘要:

为提高突发性灾害中人员伤亡快速估计的精度,识别不同空间状态下人员死亡率的差异,基于村镇居民生活模式调查(HAPRRES)数据和由此建立的人群生活模式参数模型库,仿真估计2005—2018年我国13场地震发生时人员空间状态分布,优化获取地震毁坏房屋内睡眠与清醒状态人员的死亡率模型。分析结果表明:毁坏房屋中入睡者的死亡率(5.16‰)是清醒者死亡率(0.85‰)的6倍;土坯房毁坏时,入睡者的死亡率(1.60%)是清醒者死亡率(1.34‰)的11.9倍,而非土坯房毁坏时入睡者的死亡率(2.35‰)是清醒者死亡率(0.54‰)的4.3倍。文中获得的死亡率模型具有较好的稳健性。

Abstract:

Efficient estimation of casualties in earthquake scenarios involves the identification of mortality rate variations among individuals in different spatial states, which may be achieved through the simulation and replication of population spatial distributions during earthquakes. Based on the human activity pattern model set which was generated from the China Human Activity Pattern of Rural Residents Survey (HAPRRES), we simulated individuals' activities during 13 earthquakes in China from 2005 to 2018 to estimate the spatial state snapshot distributions of the earthquake affected areas at their onset moment. These estimates allowed the optimization of mortality rate models by distinguishing between sleeping and awake people in earthquake-damaged houses. The optimized mortality models reveal that the mortality rate for individuals asleep (5.16‰) is six times higher than that for individuals awake (0.85‰) in seismically collapsed houses. Notably, when the adobe houses are destroyed, the mortality rate of sleeping people (1.60%) is 11.9 times higher than that for the awake people (1.34‰). Conversely, during the destruction of non-adobe houses, the mortality rate for the sleeping people (2.35‰) is 4.3 times higher than that of the awake people (0.54‰). An uncertainty analysis proves the robustness of the mortality rate model. As this explorative research demonstrates, incorporating human activity pattern model will help to improve the rapid estimation of casualties of sudden disasters.
