摘要

概述了区域泥石流灾害的风险分析体系，指出了过去区域泥石流灾害危险性研究中的某些误区以及区域社会经济易损性评价的难点。借助于“灾害熵”的概念，提出了区域泥石流灾害危险性定量分析的一种新方法。通过将泥石流灾害的危险性和区域社会经济易损性进行分级，建立了风险评价矩阵。在此基础上，对区域泥石流灾害的风险进行了分级，可为有效地进行区域泥石流灾害的预警，以及为减灾防灾奠定了坚实的基础。

Abstract

The risk analysis system of regional debris flow hazards is briefly discussed; and some mistakes on the study of hazards analysis of regional debris flow and difficulties on the assessment of social economic vulnerability are indicated. By means of the conception of “hazard entropy”

a new approach for quantitative risk analysis of regional debris flow hazards is brought forward. A risk assessment matrix is built up through grading the hazards of regional debris flow and the social economic vulnerability. On the basis of risk assessment matrix

the risk of regional debris flow is graded; and it will lay a solid foundation for effectively early-warning of regional debris flow and reducing and preventing hazards.
