Impact of Urban Spatial Form on Daytime Land Surface Temperature in Communities of Wuhan

Due to the rapid urbanization, the impact of urban spatial form on surface temperature cannot be ignored and is becoming increasingly significant. This study investigates the impact of the urban spatial form which includes building form and urban land surface moisture (ULSM) on the land surface temperature (LST) of communities in Wuhan, China. The LST was retrieved in the summer and winter by Landsat 8 OLI/TIRS data. Thirty typical communities in the three-ring area were selected to represent general residential area in Wuhan. By extracting the building height (BH), building density (BD), floor area ratio (FAR), sky view factor (SVF), frontal area index (FAI) and ULSM of each community, the result shows that BH, BD, FAR, SVF and ULSM are critical variables in lowering LST in both winter and summer.
