    对地质灾害易发性危险性易损性和风险性的探讨

    DISCUSSION ON SUSCEPTIBILITY,HAZARD,VULNERABILITY AND RISK OF GEOLOGICAL DISASTER

    • 摘要: 论述了地质灾害易发性、危险性、易损性和风险性的基本概念。易发性是对某一地区地质灾害发生难易程度的描述,反映物理地质现象;危险性是灾害规模和发生概率的函数,反映灾害的活动程度和破坏能力;易损性表明社会经济易损程度及人类社会应对灾害的能力;风险性是灾害自然属性和社会经济属性的结合统一体,表达为危险性和易损性的乘积。在此基础上阐述了其影响因素和计算方法。认为这种由浅入深、由表及里的思路可应用于地质灾害评价研究及风险管理当中,具有较好的发展前景。

       

      Abstract: In this paper, the fundamental concept of geological disaster susceptibility,hazard vulnerability and risk are expounded.The susceptibility describes the complexity to occur geological disaster in a certain district and reflects physics geological phenomena. The hazard is a function of scale and probability of disaster occurrence, reflects activity degree and damage capability of disaster. The vulnerability indicates vulnerable degree of social economy and human society capability to disasters. The risk is a connecting unity of natural and social attribute of disaster, and it is the product expression of hazard and vulnerability. Based on this, it's influence factors and calculating methods are described. It is supposed this thoughts which from shallow to deep and from external to internal may be applied to research on geological disaster assessment and risk management. And it has a better developmental prospect.
