The primary objective of this scholarly investigation is to elucidate the intricate interplay between the urban heat island (UHI) effect and municipal green spaces. The focal geographic scope comprises the four locales characterized by the highest rates of urbanization within Shijiazhuang city. To conduct this inquiry, ECOSTRESS remote sensing imagery of said locales was acquired during distinct temporal intervals—morning, midday, and evening. Concurrently, pertinent urban demographic data, derived from the city's comprehensive road network cartography, was assembled. The dataset was subjected to meticulous analysis and statistical scrutiny through the utilization of ArcGIS 10.7 software. The overarching aim was to discern the nuanced impact of urban parks on the surface temperatures of their proximate environs during the summer season.The findings of this investigation revealed that, in order to effectively ameliorate the discernible heat island effect (SUH), rejuvenation initiatives ought to be directed toward sites maintaining a distance from green spaces within the range of 160 to 370 meters. Furthermore, augmentation of green space configurations is recommended in vicinities characterized by building densities falling within the range of 0.2 to 0.3. Notably, in locales marked by high building density, park layouts should adhere to a more regularized design during the renovation process. Additionally, it is advisable to ensure that the spatial separation between distinct urban parks exceeds 900 meters.These empirical insights are poised to enhance the comprehension of urban planners regarding the intricate dynamics through which urban parks exert influence on municipal surface temperatures. Furthermore, the discerned patterns furnish pragmatic guidance for mitigating the heat island effect, thereby offering invaluable recommendations for urban planning endeavors.
