Abstract

In this paper, 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 are considered. Taking, Henan Province as the focus area, and county as the administrative unit, both the hazard assessment map and the vulnerability assessment map of the flood disaster are acquired based on GIS and AHP integrated method. Finally, the comprehensive hazard evaluating map of the flood disaster was drawn. The case study shows that the GIS-based category model is effective in flood risk zonation. Therefore the paper has a certain theoretical and practical significance.
