中文摘要	泥石流灾害损失评价是对已经发生的泥百流灾害所造成的损失进行综合性的测算和统计。它是泥石流灾害评价的重要内容之一。一次泥石流灾害，除了直接造成人员伤亡和财产损失外，还可能伴有潜在的间接影响。此外，时间和空间分布状况的不同也增加了评价的难度。所以，泥石流灾害损失评价是一项复杂的工作。灾害损失的严重程度需要通过适当的指标来反映。根据承灾体特点，文章初步建立了泥石流灾害损失评价指标，分别为人员损失、经济损失和救灾投入费用，并且对于每个指标给定了相应的计算方法。人员损失主要由因灾死亡损失和因灾伤害损失两部分构成；经济损失包括直接经济损失和间接经济损失。直接经济损失集在在建筑、资产、交通、管线、资源5个方面，间接经济损失则通过与直接经；声损失的比例关系来进行换算；救灾投入费用是灾害发生后进行救援、治理、恢复等所花费的费用。最终的灾害总损失等于上述3部分损失之和。在此基础上，综合时间和地域因素，提出了灾害损失的时空比较方法，从而增加了评价的科学性和合理性。泥石流灾害损失评价为定量反映灾情、进行泥石流救灾优先性工作提供了依据。
英文摘要	Economic-social valuing and environmenta-l economic integrated evaluations are needed in feasibility research reports on the geo-disaster prevention and cure project . Now, there are hundreds of debris flow feasibility research reports on cure prevention and cure projects and more than 200 landslide feasibility research reports of cure projects in the Three Gorges Reservoir area, which can not well explain the importance of the prevent ion and cure project because of the simple qualitative depict ion and taking total worthiness in the undertaking disaster body area as the economic benefits. Therefore, we make the quantificational evaluation model and method used for the geo-disaster design company, which can enhance the level of the feasibility research on the geo-disaster prevention and cure project. The economic benefits of prevent ion and cure the mud-rock flow is the ratio of utmost economic loss reduced possibly with invest. The financing tax rate of prevention and cure project equals to the ratio of utmost possible economic loss for the geo-disaster minus the cure invest with the cure invest ; the direct economic benefit of prevention and cure project equals to utmost possible economic loss minus cure invest; the ratio of devotion with output equals to prevent ion and cure invest with utmost possible economic loss. There are two steps in the evaluation method. The first step is to survey the undertaking body in the area endangered by the mud-rock flow, and the second step is to value the economic benefits of prevent ion and cure the mud-rock flow. There are 4 facets in the valuing content. The first part is outline of the prevention and cure project; the second part is the basic data of the economic evaluation; the third part is to calculate the economic benefits; and the last one is to evaluate the economic benefits. In the end, we validated our model and method with the case of Nanxi Debris Flow in Chenzhou City in Hunan Province.
