Abstract

In this paper, a typical life loss model for earthquake disasters is used to verify and calculate the historical earthquake cases in Gansu Province since 1966. The accuracy and applicability of various models in Gansu Province are studied through actual earthquake cases. The study results shows that: ①when the earthquake magnitude is lower than 5.5 or between 5.5 and 6, The live loss assessment model based on population density proposed by Badal, the assessment model of life loss based on epicenter intensity proposed by Liu Jinlong, and the national emergency assessment model for earthquake disasters are show minimum-error and have the best comprehensive effect; When the earthquake magnitude is higher than 6, needs to analyze the characteristics of the natural geography, the social economy and other aspects of the assessment area to get the comprehensive evaluation results to support the emergency decision. ②The assessment results of the life loss model of seismic disaster in the space are obvious regionally: The accuracy of the earthquake model evaluation in the Hedong area of Gansu is not as accurate as that in the Hexi region. In the research of life loss assessment model for earthquake disasters, it is particularly important to build a typical assessment model for regional seismic loss characteristics. In addition, the prospects on the problems in the current life vulnerability models in earthquake disasters and the future development are presented.
