Index system of debris-flow hazard assessment
Chen Xiao-qing · Ziran zaihai xuebao · 2001
Establishment of index system ought to satisfy applicability, completeness, and comparable, synthetic and systematical properties. And choice of indices should also satisfy some certain de- mands. Any evaluation result should be compared with others. A disaster network figure was ob- tained on the base of analysis of objects under the threat of debris flows. Structure model of assess- ment index system was then proposed. And, calculation and determination of various indices, with their weights, were also proposed. In conclusion, index system of debris flow loss assessment was established, consisting of the goal hierarchy in terms of hazard degree, the rule hierarchy in terms of economical loss and social and environmental impaction, and the index hierarchy in terms of as- sessing factors and indices.
