沙尘暴灾害风险评估指标体系初探

A Preliminary Discussion on Risk Assessment Index System of Sandstorm Disasters

以自然灾害系统理论为基础,阐述了沙尘暴灾害风险的概念;从致灾因子危险性、孕灾环境稳定性和承灾体脆弱性三个方面分析了沙尘暴灾害风险构成;根据其风险构成特点初步研究了这三个方面的风险评估指标,探讨了这些指标在沙尘暴灾害风险评估中应用的意义。

Based on the theory of natural disaster system,the concept of sandstorm disaster risk is expounded,and the composition of the risk is analyzed in three aspects as the danger of disaster-causing factors,the stability of hazard inducing environment and the vulnerability of hazard bearing bodies.The risk assessment indexes of the above-mentioned three aspects are researched according to the composition characteristics of the risk,and the significance of the indexes application in the risk assessment of sandstorm disaster is discussed.
