摘要
在综述国内外自然灾害风险损失评估研究成果的基础上,运用归一化原理,对灾害风险度和灾害损失度的相对等级进行了划分,提出了单一灾种和复合灾种灾害风险损失度相对等级的划分方案和划分方法,然后依据不同灾种在时间上和空间上的叠加性以及机理上的关联性,对区域自然灾害风险损失等级评估方法和评估体系进行了初步探讨。
By summarizing researches on assessment of risk loss of natural hazards at home and abroad,the relative degrees of hazard risk are given by using normalization principle. A program and method for dividing the relative levels of risk loss of single and compound hazards are put forward. Then,methods and a system for assessment of degrees of regional natural hazard risk loss are discussed in the light of spatial-temporal superposition and mechanism correlation of different hazards.
