Examining the Effect of Green Infrastructure Configurations and Patterns on Urban Thermal Environment in Incheon, South Korea

다국어 초록 (Multilingual Abstract)

Rapid land cover modification in urban areas has worsen the urban thermal environment by replacing natural vegetation and agricultural lands with impervious surfaces. As increased temperature in urban areas causes detrimental effects on both humans and the ecosystem, optimizing urban greenspace has been suggested to mitigate the urban heat island effect. However, there is insufficient research on the effect of spatial composition and pattern-size, shape, isolation, and connectivity-on extreme heat vulnerability. This study conducts hot spot analysis and a step-wise multivariate regression analysis at the smallest jurisdiction scale level in Incheon, South Korea to examine whether landscape metrics affect the land surface temperature. The findings show that by increasing the number of small patches rather than providing continuous large green spaces within urban areas is effective for controlling the urban thermal environment. In addition, small and less fragmented green spaces tend to have a better effect in reducing mean land surface temperature, and green spaces that are close together can minimize extreme heat events in urban areas.
