Yao Wenhua · Anhui nongye kexue · 2009
Based on theory and method of multi-grade fuzzy evaluation,combined with the characteristics,causes and mechanisms of landslides,the study establishes a new evaluation model for debris flow disaster easy-happening.Minimum square method and comparative law are used to determine weight of evaluation factor.Selecting typical evaluation index and establishing second level fuzzy similar inference,evaluating the debris flow easy-happening,the result showed that Shangzhuogou debris flow belongs to medium easy-happening,multi-grade fuzzy mathematics comprehensive evaluation model is suitable to evaluate the debris flow easy-happening.
