Preliminary study of the influence of the spatial arrangement of urban parks on local temperature reduction

As more of the population resides in urban areas, the magnitude of the urban heat island effect may increase accordingly. Parks can create a cool island effect, adjust the urban microclimate, and improve the urban thermal environment. In the past, many researchers have utilized field measurements and numerical simulations to study the cooling effects and influential factors of parks. The current study is based on previous research on park cooling effects and utilizes an ENVI-met model to characterize the influence of the spatial arrangement of urban parks on local temperature reduction. The results indicated that different spatial arrangements of parks exhibited significant differences in outdoor cooling effects. A larger total park area, a greater number of parks, a greater area of the largest park, more evenly distributed park spaces, and more park diversity led to more dramatic outdoor cooling effects.
