摘要：
According to the basic principles of flood risk and the stability of hazard-pregnant environment, this paper took the coastal areas in southeastern Asia as the study area, indexes including DEM, land use, vegetation and river density, were combined in this study. Preprocessing models provided by GIS software were used to standardize related parameters, and the standardized multi-source datasets in raster format were obtained. The weights of indicators were determined through the Analytic Hierarchy Process (AHP) approach. Then a comprehensive disaster environment rating map was generated through the map algebra functions in GIS, and corresponding analysis of the rating map was carried out.
