As population and resource consumption are concentrated in cities due to the recent accelerated urbanization, deepening social problems such as fine dust, traffic congestion, water shortages, and disasters are a major threat to the sustainability of cities. In particular, in the 2018 National Consciousness Survey, Korea needs countermeasures to solve the increase in disaster-prone areas due to climate change and new environmental issues. In particular, climate change is occurring not only in Korea but also around the world, and accordingly, various countermeasures related to disasters and disasters are being promoted. These countermeasures can be seen in two aspects: the first is to mitigate the causes of climate change, and the second is to prepare in advance for the effects of climate change. The former aspect is that civil society and companies are actively participating, but the latter aspect is that the same damage does not occur in all classes or regions, but the damage caused by the interaction between physical and environmental differences may be different. Accordingly, it is necessary to prepare measures that reflect accurate predictions and regional characteristics in the preliminary preparation and follow-up process. Also, smart cities are being promoted worldwide to solve urban problems along with climate change. However, since the smart city currently being promoted is focused on the ICT field, the problem of insufficient value enhancement in various fields is mentioned. In order to respond to disasters caused by climate change comprehensively, it is necessary to establish an infrastructure that allows cities to take responsibility for climate change and respond efficiently. Therefore, the purpose of this study is to minimize domestic damage caused by abnormal weather through a comprehensive vulnerability analysis of climate change in Seoul and to suggest countermeasures that citizens can feel and utilize. In order to achieve the purpose of the study, a spatial vulnerability analysis was conducted focusing on 25 autonomous districts in Seoul on heat waves, floods, fine dust, and cold waves using the geographic information system GIS. The process of the study first constituted social, physical, environmental, and economic indicators for climate exposure, sensitivity, and adaptability sectors for spatial vulnerability analysis. Based on the results of the vulnerability analysis of autonomous districts, vulnerability was evaluated using the VRI calculation method to select autonomous districts with high vulnerability. Next, the characteristics of social, physical, environmental, and economic vulnerabilities by region were derived through the analysis of the administrative dong units of the selected autonomous districts. Based on this, disaster response measures related to domestic climate change were comprehensively summarized and then regional disaster response measures were presented, focusing on immediately after and after the disaster. Accordingly, vulnerable areas needed information and physical infrastructure for rapid evacuation of citizens, vulnerable areas in the sensitivity sector needed physical resources and post-economic support, and vulnerable areas in the adaptability sector suggested countermeasures considering the need to expand the post-recovery process. This study reflects the regional characteristics of each natural disaster, suggesting the direction of countermeasures to reduce manpower, time, and budget requirements, and the need for appropriate implementation of the response system at the time of the disaster. In addition, there is a limitation in that it was not possible to determine whether there was a high correlation with the actual damage of the region because it was analyzed with the processed data. Therefore, in future studies, it is necessary to identify the current status of disasters and identify correlations with indicators to suggest more practical and broader use of urban and architectural planning fields in consideration of selecting appropriate locations for disaster reinforcement infrastructure.
