| 摘 要： | 根据影响洪水灾害风险的致灾因子危险性、孕灾环境稳定性与承灾体易损性,以淮河流域为示范研究区,以县为行政单元,综合考虑降雨、径流量、河流、地形、人口、经济等指标,基于GIS与AHP集成方法得到了淮河流域洪水灾害危险性评价图和淮河流域洪水灾害脆弱性评价图,并采用"加"模型计算公式得到了洪水灾害综合风险评价图,进行了相应的结果分析。 |

| Abstract: | According to the flood risk-influencing hazard of disaster-formatire factors,the stability of hazard-pregnant environment and the vulnerability of hazard bearing body,the indexes of precipitation,runoff,river,terrain,population and economy were considered in this paper.Taking,Huaihe River Basin as the focus area,and county as the administrative unit,both the hazard assessment map and the vulnerability assessment map of the flood disaster in Huaihe River Basin were acquired based on GIS and AHP integrated method.Finally,the comprehensive hazard evaluating map of the flood disaster was drawn by a "plus" model,and corresponding analysis of the risk map was carried out. |
| Keywords: | geographic information system(GIS) analytic hierarchy process(AHP) flood disaster flood risk assessment |
