For this purpose, was done Study of the efficiency of thermal bands and land use changes in determining the surface temperature index using a separate window algorithm in the Bandar-e Emam Khomeyni of Khuzestan province by Landsat 8 satellite imagery. Based on this, was used vegetation index (NDVI) for band ratio between the red and near infrared bands to prepare the LST map and were used four seasonal images in 2016-2017 years. The results of the comparison of the two thermal bands showed that the thermal bond 11 is higher accuracy than the thermal bond 10 (RMSE = 3.6 for the band 11 and RMSE = 4.4 for the band 10) because the wavelength of it is higher. Also, the estimation of the comparison of satellite imagery data with ground truth showed a high accuracy (R2 =0.9). Comparing the temperature of the users was determined that the industrial and urban areas more effective on increasing LST than the vegetation and water areas. Base on bands ratio between near and red infrared bands showed that the vegetation index decreased with increasing temperature. So, the lowest amount of vegetation was estimated in August (-0.42) and the highest was in October (0.35).
