The intensifying heat island effect and rising temperatures in Seoul pose a serious threat to the city¡¯s residents and the urban environment. This study aims to identify the characteristics of urban spaces in both hot and cold spot areas during all four seasons for one year, using S-Dot temperature data. It also analyzed the impact of the main components of urban space in the concentrated area of heat island intensity. Temperature data from Seoul and its surrounding suburbs were analyzed for heat island intensity and spatial autocorrelation. The order of heat island intensity was fall>spring>winter>summer, with the number of administrative dongs in hotspot areas in the order of fall>summer>spring>winter, and the number of administrative dongs in cold spot areas in the order of winter>spring>autumn>summer. Significant differences were found in green areas, commercial land, apartments with 16 floors or higher, apartments with 5 to 15 floors or higher, detached houses, elderly population, and population density during all four seasons. This study identified the UHII concentration areas of heat island intensity during the four seasons, finding that the hotspot area was mainly located in the northeast and northwest regions, while the cold spot area was distributed in the northeast regions. The regression analysis results involving the main components of urban space in the UHII concentration area revealed the influence was large in the order of open space>high-density development area>high-density residential area>high-density residential area. This study is meaningful in that it provides insights into the phenomenon of heat islands in Seoul throughout the four seasons, identifies the effect of urban space main component factors in the UHII concentration area, and derives important implications for future heat island mitigation strategies. |
