| 摘 要： | 在深入研究炉霍县泥石流灾害的基础上,以实地考察数据为依据,以层次分析法为技术方法,对炉霍县泥石流易发性进行了评价。选取高程、坡度等8个指标作为影响泥石流易发性的评价因子,通过建立系统层次结构,构建判断矩阵,从而求出各因子的权重,建立泥石流危险性评价模型。实践证明,基于层次分析法的泥石流灾害易发性评价是有效和实用的。 |

Application of Analytic Hierarchy Process in Evaluating the Easy Eruption of Debris Flow Disaster in Luhuo County |
|
| Abstract: | On the foundation of the deep study on debris flow disaster in Luhuo County, this paper evaluated the easy eruption of the debris flow based on the data of the field investigation and the Analytic Hierarchy Process technique. It worked out the weight of each factor and established a evaluation model on the risk of debris flow through selecting eight indexes such as the height, ratio of slop as the influential evaluated factors for the easy eruption of the debris flow and the establishment of system hierarchy structure to construct judgment matrix. Through practices, it had been proved that the evaluation on the easy eruption of the debris disaster based on the AHP is effective and practical. |
