Purpose: Continuous natural disasters caused by climate change are damaging people"s lives and property. Among them, heat waves are closely related to the physical elements of urban space. In order to improve this, practical research based on urban space thermal environment is required, and in particular, microscopic spatial pattern analysis is needed in a decline city that is very vulnerable to heat waves. Therefore, this study analyzed the spatial correlation of physical elements of urban space due to heat wave vulnerability in the area of Bisan 2·3-dong, Seo-gu, Daegu Metropolitan City. Method: Through previous studies, factors due to heat wave vulnerability were derived in microscopic space. Afterwards, correlation analysis was performed on the measured urban space thermal environment and spatial patterns through the "Kernel Density Estimation" analysis using the "Arc GIS Pro" program. For correlation analysis, "Pearson"s Correlation Analysis" analysis method was used. Result: The Hazards and vulnerability indicators classified in this study showed a positive correlation with the measured urban space thermal environment. In addition, the adaptive capacity indicator showed a negative correlation, proving the spatial correlation between the heat wave vulnerability indicator presented in this study and the urban space thermal environment.
