Debris Flow Risk Assessment Based on Model of Entropy Weight Attribute Recognition

结合工程实例,将属性识别理论应用到重庆地区泥石流危险性评价中,从而把定量分析与定性描述有机地结合到一起。提出了泥石流危险性评价的属性测度计算方法,并利用熵权系数法确定权重,建立了基于熵权系数法的属性识别计算评价方法。评价结果表明该方法具有可行性和推广应用价值。

Based upon attribute recognition and combined with practical work, attribute recognition model is applied to complex debris flow risk assessment in Chongqing area. The methods combines both quantitative anal-ysis and qualitative analysis together. The calculation method of attribute measurement is proposed for debris flow risk assessment and the entropy method-based attribute recognition model is put forward through calculating weight coefficient by entropy method. The results show that the proposed method is feasible and deserves popu- larization.
