摘　　要： 介绍了几种国外常用的生命风险定量评价方法,重点论述了生活质量指数(LQI)方法,包含财富和寿命在内的综合社会指数,用来评价生命风险管理决策的合理性。尝试将生活质量指数用于泥石流灾害生命风险研究中,以2007年四川省典型泥石流灾害为例,通过人均GDP、工作休闲时间比和人口预期寿命3个指标评价了减轻生命风险的成本,即灾害生命损失经济价值。结果显示,其大小超过了直接经济损失的总和,说明大型和特大型泥石流灾害中减轻生命风险的突出重要性。 Loss of life is the most serious consequence of disaster risk, and life risk assessment has several problems to be solved, of which the controversial problem is the monetary value of human life. Foreign scholars prefer to study life risk at the cost of reducing the risk, and discuss its acceptance. Based on the theory of life risk, this paper introduces kinds of quantitative assessment methods of life risk commonly used abroad. It derives that the combination of life risk assessment and acceptable risk conforms to modern risk management concepts and Life Quality Index （LQI） is such a criterion. LQI is a comprehensive social index including wealth and health, and it is used to assess the rationality of life risk decision-making. On account of moral and ethical principles, LQI resolves optional safety cost of life risk according to acceptable risk principles. This paper attempts to use LQI to estimate life risk of debris flow disaster with three indicators which are GDP per person, work/leisure time ratio, and life expectancy. To take typical debris flow disasters in Sichuan province in 2007 as examples, the authors calculate the optional safety cost equal to monetary value of life risk and the outcome is more than the sum of direct economic losses, which highlights the importance of life risk in large-sized debris flow disasters.
