Flood risk zoning in China
摘要
Abstract
The occurrence of flood disaster is usually affected by climate, topography and river net system. Therefore, six factors including maximum 3-day precipitation, climate zoning, the magnitude of slope, Digital Elevation Model （DEM）, buffer zones of river nets and lakes, and statistic data were selected to represent this kind of effect in this study. The weight for each factor was determined by the combination of cause analysis of flood formation and the analytic hierarchy process. The flood zoning map of China was obtained through overlay analysis by using Geographical Information System （GIS）. Potential economic and social impacts of flooding were assessed using the distribution of population and Gross Domestic Product （GDP）. The zoning map obtained is consistent with historically statistical flood zoning and it indicates that the technique used in this paper was suitable to analyze the spatial characteristics of flood risk in China.关键词
