基于熵权的洪灾风险空间模糊综合评价模型
Spatially fuzzy comprehensive assessment model for flood hazard risk based on entropy weight
摘要
Abstract
Entropy theory was used to combine with traditional fuzzy comprehensive assessment method to develop a spatially fuzzy model for flood hazard risk in this work. To improve weight allocation, weight coefficients of evaluation factors were derived from the available data reflecting information entropy. Application with GIS to the Dongjiang river basin indicates that the highest risk of this basin appears in the regions of Heyuan city, Huizhou city, Huiyang district, Dongguan city and Bao'an and Longgang, while the relatively safe region covers mountainous areas less economically developed in the lower-middle Dongjiang. Comparison with a few historical floods of the basin shows that the assessment map agrees well with the observed flood risk and it provides a reference for flood control and disaster assessment.关键词
