摘要
本文在文献[1]泥石流危险度研究的基础上.提出泥石流危险性评价的模糊数学方法。文中首先根据有关资料建立了评定因子的隶属函数以及各因子在评定泥石流危险性中权重的模糊子集,并在此基础上运用模糊综合评判技术提出了确定泥石流危险等级模糊向量的方法。
On the base of the research results of hazard degree of debris flow presented in refer-ence[1],through using available data and information,this paper gives the membershipfunction of evaluation factors and the fuzzy subset which is used as weigh factor in deter-mining debris flow hazard.Based on this result,a fuzzy set vector method to determinehazard degree of debris flow is provided by use of comprehansive evaluation algorithm
