| 摘 要： | 中国地震灾害发生频繁,因此进行有关地震灾害风险性分析十分必要。本文在分析地震灾害形成的各主要因子的基础上,结合1900-2009年地震灾害数据,建立了地震灾害风险评估模型,定量确定了各风险性影响因子。最后利用ArcMap软件的栅格计算功能,对于地震灾害中最重要的人口因素进行了分析,形成了中国地震灾害人口风险性分布图,并划分出了人口高风险区。

| Abstract: | Since the earthquake disaster frequently occurred in China,it is necessary to do some research on the risk analysis of earthquake.The paper first analyzed major factors of earthquake disaster,then established earthquake disaster risk assessment model based on the data of earthquake disasters between 1900 and 2009,and determined the value of three factors quantitatively.Finally,through using the spatial analyst function of ArcMap system,this paper analyzed the risk of population in earthquake disaster and created the population risk distribution map with a division of population high risk areas. |
