Abstract
Investigating the distribution of thermal radiation and its relationship with the existing uses is very important in understanding the microclimate of urban areas. The purpose of this study is to monitor land use changes and its relationship with the surface temperature using Landsat satellite images during a 20-year period (1998-2018) in Bandar-Abbas city. In this study, after applying processing on satellite images and then using thermal equations and Sabal algorithm, the surface temperature of the earth was calculated for the study periods. The results show a decreasing trend of vegetation cover from 1998 to 2008 and an increasing trend from 2008 to 2018. In 1998, the amount of vegetation between (0.2 and 1) was 130 hectares and in 2008 it reached 95 hectares and finally in 2018 it increased to 115 hectares. The temperature in the northern and northeastern regions has always been higher than other regions during the statistical period, and the lowest temperature is in the south due to the presence of water and in the center of the city due to the presence of vegetation. Temperatures increased by 5 degrees from 1998 to 2008, but decreased by 8 degrees from 2008 to 2018 in the center of the city and most parts.
