| 英文摘要 | Risk assessment is essential for managing risks and developing mitigation efforts related to debris flow hazards. The results of debris-flow risk assessments can be used as a scientific basis for planning regional economy, formulating national land use policies, selecting project sites, monitoring and controlling disasters and developing environmental conservation measures. Therefore, developing and applying effective methodologies for risk assessment becomes imperative. Risk assessment mainly involves establishing an index system and developing related methodologies. Disagreements exist among scientists on these two aspects. By summarizing previous achievements in risk assessment, this paper mainly discussed the theory, index and methodologies as well as future trends in risk assessment of debris-flow hazards. New fields of risk assessment on debris-flow hazards are recommended. A case study based on geographical information system (GIS) is given. In the past several decades, the assessment of debris flow risks has undergone several stages, namely from qualitative assessment to semi-quantitative assessment, from which to quantitative assessment, and various assessment methods have been advanced. The index system proposed by the authors in this paper is based on the hazard and vulnerability analysis, with the analysis of the expected loss as its core element. The hazard of debris flows, and the vulnerability and the expected loss thereof are the three primary parameters and form an index system of the risk assessment concerning debris flows. The proposed methodologies have been used to assess debris-flow hazards occurring in the Jinsha River Basin, China. The results demonstrate that debris-flow hazards can be assessed successfully through systematic assessment methods, and the adoption of new technologies, such as GIS and remote sensing, can improve the accuracy and efficiency of the risk assessment of debris-flow hazards. |
