Abstract

Using analytic hierarchy process and entropy method to determine the weight of index, fuzzy comprehensive evaluation model of risk assessment was constructed in this paper. Flood risk index and risk rating of area along the Yangtze River in Anhui province were drawn by using GIS spatial analysis technology. From disaster causing factors, inducing environment and bearing body, average maximum 3 day rainfall, rainstorm number, vegetation coverage, river network density, standard deviation of the elevation, population density, proportion of rural population, density of GDP, per capita net income of farmers, and cultivated land area ratio were selected as evaluation indicators. The results show that flood risk rating and risk index of area along the Yangtze River in Anhui province has a spatial distribution characteristics from south to north gradually reduced.
