摘要
在深入分析河北省元氏县佃户营泥石流灾害的基础上,采用可拓层次分析法(EAHP),选取12个指标作为评价泥石流危险性的因子,建立了佃户营泥石流危险性评价模型。利用该模型对佃户营泥石流沟进行危险性评价,其结果与实际情况具有较好的一致性。研究表明,运用可拓层次分析法(EAHP)进行泥石流危险性评价实用且有效。
Based on analyzing of debris flows in Dianhuying village of Yuanshi County,Hebei Province,by using of extenics analytic hierarchy process（EAHP）method,12 indicators were seleted as the assessment factors to evaluate debris flow risk degree.The debris flow risk assessment model was established for Dianhuying village.Then the model was applied to assess the risk degree of local debris gullies.The result has good consistency with the actual situation.It is practical and effective to evaluate the debris flow risk in Dianhuying village of Yuanshi County,Hebei Province,by using EAHP method.
