摘　　要：当前防震减灾工作重心已从灾后应急救援转向灾前风险防控,从被动地震灾害止损转为主动降低地震灾害风险,建设地震灾害风险评估与服务系统可以为减轻地震灾害风险、增强地震灾害风险防范能力提供有力支撑。文章从四川省地震危险性高、地质灾害风险高、承灾体暴露度高、承灾体脆弱性差异巨大的地震灾害风险形势出发,以地震灾害风险防治需求目标为导向,聚焦于地震灾害风险评估与区划及信息服务,对四川省地震灾害风险评估与服务系统的总体架构、功能和业务流程进行设计,运用大数据、云计算、空间信息等技术,研发地震灾害风险评估与服务系统。实现多源异构地震灾害风险数据资源整合,推动地震灾害风险评估流程化,提升地震灾害风险防治信息服务能力。The current focus of earthquake disaster prevention and mitigation work has shifted from postdisaster emergency rescue to predisaster risk prevention and control and from passive prevention of earthquake disasters to active reduction of earthquake disaster risks.The construction of earthquake disaster risk assessment and service systems can provide strong support for reducing earthquake disaster risks and enhancing the ability to prevent earthquake disasters.This paper started with the earthquake disaster risk situation of Sichuan Province,which was characterized by high risks of seismic and geological hazards,high exposure of disaster-bearing bodies,and significant differences in vulnerability of disaster-bearing bodies.Based on the needs and objectives of earthquake disaster risk prevention and control,it focused on earthquake disaster risk assessment,zonation,and information service.The overall framework,function,and business process of the earthquake disaster risk assessment and service system in Sichuan Province were designed and developed using big data,cloud computing,spatial information,and other technologies.The system integrated multisource heterogeneous earthquake disaster risk data,thus promoting the process of earthquake disaster risk assessment and further improving the information service capability for earthquake disaster risk prevention and control.
