Abstract :This study was carried out in Nilüfer district of Bursa in order to reveal the extent of urbanization, to monitor the changes in landscape elements such as water, vegetation and agricultural lands, and to examine the effects of this on Land Surface Temperature insert ignore into journalissuearticles values(LST);. For this purpose, images taken by Sentinel-2 satellites in 2017 and 2022 were used. With these images, NDVI insert ignore into journalissuearticles values(Normalized Difference Vegetation Index);, SAVI insert ignore into journalissuearticles values(Soil Adjusted Vegetation Index);, mNDWI insert ignore into journalissuearticles values(Modified Normalized Difference Water Index); and NDBI insert ignore into journalissuearticles values(Normalized Difference Built-up Index);, which are widely used in understanding terrain changes, were calculated. Time series analyzes were made between the relevant years The relationship between the changes in the field and the surface temperature was questioned by calculating the LST value with Landsat 8 OLI_TIRS images, and the relations between the indexes and the LST were evaluated by correlation analysis. The results show that NDVI, SAVI, and mNDWI are on a decreasing trend between 2017-2022, while NDBI is on an increasing trend. In other words, the results showed that the vegetation areas and water-covered surfaces decreased, while the built-up areas increased. It has been observed that the changes in Land Use/Land Cover insert ignore into journalissuearticles values(LULC); increase the LST in the west and south regions of the district.
