2. The relationship between the presence of vegetation and the cool-
ing capacity of spatial arrangement

This study investigates the relationship between the cooling capacity of
urban cool areas and spatial arrangement under the subheadings, tree covered
surfaces, grass covered surfaces, and normalized difference vegetation index.
Tree Covered Surfaces
The strongest relationship in terms of the presence of vegetation was
observed in the one between the intensity of cooling and the variable of the
total number of tree-covered surfaces (T_N). This relationship is strong and
in the negative direction between average LST (A_LST) (r= -0,658, p<0,01)
and the miminum LST (Min_LST) (r= -0,706, p<0,01) while it is strong and in
