【摘要】 依据自然灾害风险管理理论,结合致灾因子危险性和承灾体易损性构建简易的福建省滑坡灾害风险评估模型。利用1990-2013年福建省滑坡灾害的数据资料,构建滑坡灾害的数据库,编制以县域为单位的福建省滑坡灾害分布图、时间变化图和风险分布图。研究表明:福建省滑坡灾害年内变化大、年际波动上升、地区差异大;综合考虑致灾因子和承灾体的影响,福建省滑坡灾害风险高值主要分布在沙县和漳平市等闽中地区,与福建省滑坡灾害的空间分布相似。据此构建福建省滑坡灾害风险管理决策系统,提出增强民众防灾减灾意识、合理规划布局、加强监控预警、完善工程措施和风险规避等风险管理模式。为福建省滑坡灾害风险的评价与管理提供依据和方法。更多还原

【Abstract】 A simple risk assessment model of Fujian landslide is built based on natural disaster risk management theory combining with the risk of hazard factors and vulnerability of hazard bearing body. Using the data of landslide in Fujian province from 1990 to 2013,we built a database of landslide to compile maps of landslide distribution in the county as a unit with its temporal change and risk distribution. The results indicate that Fujian landslide disaster had characteristics of annual & inter-annual variation,large regional differences,considering the influence of hazard factor and hazard bearing body,the high-value areas of risk distributed mostly in the central of Fujian,like Shaxian and Zhangping,which are similar with the spatial distribution of landslides. Constructing the system of risk management and decision of landslide hazard in Fujian Province,some risk management model such as the public awareness improvement of disaster prevention and mitigation,reasonable layout,strengthen monitoring and early warning,engineering and risk aversion are proposed,which can provide basis for the assessment and management of landslides.更多还原
