Abstract

Urban heat islands are a spatial phenomenon characterized by increased temperatures in urban areas compared to their suburban and rural surroundings, driven by spatial patterns of built-up areas, land use, and land cover, as well as the absence of vegetation and variations in land surface temperature (LST). This study examines the relationship between built-up intensity, planned land use, and LST in the City of Zagreb, focusing on its core urban area. Utilizing Landsat-9 satellite data for LST extraction and urban spatial planning documents for vegetation classification, the study explores key spatial factors influencing the intensity and spatial distribution of urban heat islands. The methodological approach integrates Exploratory Spatial Data Analysis (ESDA), regression models, and spatial autocorrelation to determine the spatial dependencies between land use and temperature variation, conducted using the R programming language. The analysis identifies specific areas where built-up land use categories contribute most to temperature increases, while planned green zones have a significant cooling effect. Spatial regression highlights the varying impact of different planned land-use categories on local thermal conditions, particularly the role of designated green areas in mitigating urban heat accumulation. Spatial autocorrelation techniques confirm the presence of clustering effects in heat island distribution, emphasizing the spatial dependency of UHI formation. These results emphasize the need for an integrated urban planning approach to mitigate the negative effects of urban heat islands and improve the quality of life.
