| 摘 要： | 介绍了洪水灾害风险评估的方法,即从形成洪水灾害的机理出发,首先建立研究区的洪水危险性评价模型和社会经济易损性评价模型,然后再建立研究区的洪水灾害风险评价模型,最后利用地理信息系统(GIS)的空间叠加分析法,对研究区进行洪水灾害风险评估。 |
| 关 键 词： | GIS 洪水灾害 空间叠加分析 |

| Abstract: | The method of risk evaluation of flood hazard was introduced,that is according to the formation mechanism of flood hazard,an evaluation model of regional flood's danger and regional socio-economic vulnerability of research area were set up at first,and then an evaluation model of regional flood hazard was set up,finally,flood hazard evaluated in research area were used by Spatial overlaying analysis of geographic information systems(GIS). |
| Keywords: | GIS GIS Flood hazard Spatial overlaying analysis |
