摘要
为加强泥石流防灾减灾工作,以小秦岭金矿区大湖峪矿渣型泥石流隐患沟为例,将模糊数学理论引入泥石流危险性评价中。运用层次法分析评价因子,计算评价因子权值,建立单沟泥石流危险度评价模型。评判结果与野外实地勘测结果完全吻合。
In order to strengthen debris flow prevention and mitigation, the fuzzy theory is introduced into the debris flow haz- ard assessment with the hidden slag debris flow at the Dahuyu valley＇s ditches in the Xiaoqinling goldfield area as an example. The hierarchical method is used to analyze evaluation factors and calculate their weights, with a risk assessment model for a sin- gular ditch established. The results coincide with the field investigation.
