Investigating Spatial Distribution Patterns of Natural and Social Disaster Risks by Urban Decline Type: Case Studies of Daegu Metropolitan City and Seosan-si

This study aims to compare the difference in the spatial pattern of the Risk Diagnosis Index(RDI) and the Comprehensive Diagnosis Index(CDI) by type of urban decline. First, CDI decreases the risk of disasters as it comes close to the urbanized area in all case areas. Various strategies are needed to increase the reduction capacity, focusing on areas with a high risk of disasters. Second, there is a difference in the spatial pattern of declined and non-declined areas in the city, and this trend is different for the urban type. Seosan has relatively little influence in the reduction capacity sector, while Daegu has a high influence in the reduction capacity sector, which affects the spatial pattern of CDI. It implies CDI by urban size and regional attributes should be differentiated. Third, both RDI and CDI tend to be spatially clustered. The spatial clustering pattern of disaster risk in the declined areas is higher than that of other areas. Although the pattern of disaster risk is high in declined areas, this varies depending on urban size and declined type.
