摘要
通过对灾情评估领域文献的阅读、总结,介绍了国内外泥石流灾情评估研究的概况。并在前人研究基础上,结合泥石流灾情预评估研究现状,提出了泥石流灾情预评估模型:D=H.V-F(D-泥石流灾情程度,H-泥石流危险度,V-泥石流易损度,F-泥石流防治工程效益)。
Through reading and summarizing papers on the field of hazards assessment, this article introduces the general study situation on assessment of debris-flow hazards at home and overseas. Based on the former studies and combined with present study on assessment of debris-flow hazards, the paper gives the assessment model of debris-flow hazards; D= H · V-/P（D-The degree of debris-flow hazards,H-The hazard degree of debris-flow ,V-The vulnerability of debris-flow,/P-The benefit of project on debris-flow prevention）.
