In debris flow hazard assessment,for the deficiencies of the indexes weight method in present risk evaluation,a synthetic weighting method is established based on rough sets and grey theory,and,in combination with the fuzzy mathematics,it was applied to debris flow hazard assessment.Hazard assessment was conducted on six debris ditches in Sichuang Province,and objective and reasonable assessment results were obtained.In comparison with other assessment methods,it is proved that this method can be used to evaluate debris flow hazard more effectively and obtain a better result.
