Today, several factors, including the destruction of urban green cover and the uncontrolled increase of environmental pollutants in urban areas, lead to the confinement of solar radiation energy and the occurrence of the phenomenon of the urban heat island. It has dangerous consequences including the transmission of air pollution and toxic dispersed particles. The main purpose of this study is to identify the relationship between land use land cover and land surface temperature from 2000 to 2020. In this regard, Landsat 5 - TM and Landsat 8 - OLI_TIRS satellite images from 2000, 2011, and 2020 were used. In this study, after applying the necessary corrections and teaching the images, changes in land-use and land cover LU/LC changes and the type of changes were identified. The study result showed that built-up land has increased by 24.5 percent between 2000 and 2020. NDVI vegetation index was calculated and then LST was calculated using thermal bands, by used GIS10.8 and RS. The results showed that during 20 years, the temperature of Erbil has increased by 4C° degrees. about the correlation between NDVI and LST, the highest correlation was recorded in 2011 when R² = 0.8552 This means that the higher the NDVI ratio, the lower the LST ratio.

KEY WORDS: Landsat5-TM, Landsat8-OLI_TIRS, LU/LC, Normalized Difference Vegetation Index (NDVI), Land Surface Temperature (LST).
