Influence of Impervious Surface Area and Fractional Vegetation Cover on Seasonal Urban Surface Heating/Cooling Rates

The urban thermal environment is impacted by changes in landscape patterns resulting from expansion and seasonal variation. In order to cope effectively with heat island (UHI) effects improve the living microclimate, an analysis of heating effect impervious surface areas (ISA) cooling vegetation needed. this study, Landsat 8 data four seasons were used derive percent ISA fractional cover (FVC) spectral unmixing retrieve land temperature (LST) radiative transfer equation (RTE). FVC divided into different categories based on ranges 0–25%, 25–50%, 50–75%, 75–100%. LST calculate rate (SHR) (SCR). Finally, analyze vegetation, variations SHR SCR compared between seasons. results showed following: (1) summer, decreases as increases study area. (2) Unlike dependence FVC, trends SHR/SCR a function ISA/FVC are more complex for value ranges, especially spring autumn. (3) (heating capacity) increasing However, (cooling except summer. This shows that our methodology variation change SHR, SCR, can be interpret cover, well their environment. analytical method provides important insight analyzing It also helpful planning mitigating UHI.
