摘要: 本文首先采用基于多准则决策的层次分析评价法,根据自然灾害风险理论,将洪涝风险影响因子分为危险性和脆弱性两类,子准则层包括平均降雨量、汇流累积量、坡度、海拔和土地覆盖度、道路级别、地表产流能力7个因子,构建了道路洪涝灾害风险评价模型。然后以福建省武夷山地区为研究区,利用地形数据、气象数据及遥感影像提取土地覆盖类型数据,通过道路洪涝灾害风险评价模型,绘制了道路风险分区图。结果表明,中、高风险积水道路占比较高,主要集中在东部、西部和中南部地区。本文对道路洪涝灾害风险所进行的评价,可服务于洪涝灾害风险预警和应急救援规划。

Abstract: In this study,the AHP evaluation method based on multi-criteria decision-making is used to build a flood disaster assessment model.Two categories of factors,hazard and vulnerability,are presented based on natural disaster risk theory.There are seven sub-factors including precipitation,accumulation,slope,altitude,land cover,road category and surface runoff capability.The AHP is used to determine reasonable weights for all factors.The flood risk assessment model was established and the risk maps were produced afterwards.Wuyi Mountain region of Fujian province is selected as the study area in this work.The assessment results indicated that the roads with medium and high risks of flooding are mainly in the eastern,western and central south regions.The research results can be used as a guidance for road maintenance,emergency rescue,and early warning of road floods.This paper evaluates the road flood disasters risk,which can be used for flood disaters risk warning and emergency rescue planning.

Key words: assessment of road flood disasters risk;AHP;multi-criteria decision-making;road;Wuyi Mountain
