Abstract

In urban space, green-blue infrastructure plays an important role in regulating local temperatures against the heating effect of areas without vegetation. These areas, which shape the spatial distribution of temperature in urban space, are called urban cold islands. This study aims to develop a method for investigating the factors affecting the spatial distribution of land surface temperature (LST). A method has been proposed for extracting the boundary of urban cold islands by using remote sensing and spatial statistics methods. Cooling extend was determined as a measure in analyzing cooling capacity of urban environment. According to scope of the study, the relationship between both of size of urban cool island and cooling intensity, and cooling extend was measured, then, discussed the impact on local climate conditions. The findings showed that size of urban cool island was more effective than the intensity in explaining cooling extend. As a result, the research approach and the findings will insight for mitigation of urban heat island effect in the context of sustainable urban planning and management.
