Exploring the Influence and Time Variation of Impervious Surface Materials on Urban Surface Heat Island

Impervious surface (IS) and urban heat island (UHI) effects are always the research hotspots. However, the existing researches either ignore the impacts of IS material on UHI or fail to monitor the seasonal temporal variations of UHI. To this end, we explore the impacts of impervious surface materials on land surface temperature (LST) by analyzing their correlation and seasonal temporal variations. The results show that the mean LST for different impervious surface materials is statistically different from each other. Additionally, the contribution of IS to LST is affected by the material. Finally, the effect of impervious surface materials on LST has seasonal differences. These findings may help decision-makers develop more effective strategies to alleviate the urban heat island phenomenon.
