Optimizing urban greenspace spatial pattern has been widely recommended to mitigate urban heat island (UHI) effect, mainly based on the statistically significant relationships between temperature and measurements of urban greenspace spatial pattern at local scale within a city. However, the scientific evidence at the city level is scarce, even though the importance of urban greenspace spatial pattern in mitigating UHI effect at the city level has been recognized. This study aims to fill this gap by investigating the relationship between the city level surface UHI intensity (SUHII) and a series...
