Abstract

Abstract

The Longwu river basin is prone to disasters due to its special geological environment. A scientific evaluation model and zoning indexes are established by collecting previous geological information and field survey data. The weight value of each inducing factor is determined according to expert scoring. ArcGIS is used for quantitative normalization processing of each factor. The disaster risk assessment results are obtained through overlay analysis and calculation.
