摘　　要：2023年12月18日午夜,我国甘肃省临夏州积石山县发生6.2级地震,地震造成灾区严重的人员伤亡、建筑物和基础设施损失。该地震造成遇难和失踪人数达151人,相对于其震级大小,是典型的“中震大灾”。本文初步分析了积石山地震区域地震构造与震源破裂特点、人口与房屋建筑分布与抗震能力影响、地震次生地质灾害的作用,以及地理气象环境、发震时间与季节等因素对加重本次地震灾害的影响。结果有助于开展综合多因素的地震灾害损失评估方法研究,提高地震损失评估的准确性,提升震后应急处置效果。At midnight on December 18,2023,a M6.2 earthquake occurred in Jishishan County,Linxia Prefecture,Gansu Province,China.The earthquake caused serious casualties,buildings and infrastructure losses in the disaster area.The earthquake caused 151 deaths and missing persons,which is a typical“moderate earthquake disaster”relative to its magnitude.In this thesis,the characteristics of seismotectonics and focal ruptures in the Jishishan earthquake area,the distribution of population and buildings,and their effects on the seismic capacity are preliminarily analyzed,as well as the role of secondary geological disasters caused by earthquakes,the influence of geographical and meteorological environment,the time and season of earthquake occurrence on the aggravation of the earthquake disaster.The results are helpful to carry out the study of comprehensive multi-factor earthquake disaster loss assessment method and improve accuracy of earthquake loss assessment,improving effect of emergency response after earthquake.
