Mapping land use land cover (LUCL) and its influence on land surface temperature (LST): A case study in Dau Tieng district at Binh Duong province

At present, land surface temperature (LST) is an important index in monitoring the urban heat is-land phenomenon and changes in local climate, as well as global climate. By analyzing the variation in land use land cover (LULC), we can see how changes in LULC will lead to changes in LST and understand the expansion of urbanization related to LST. This study used Landsat 8’s thermal infrared band to extract and calculate LST values in DauTieng district in the period 2015-2022. In addition, this study also classified LULC by using the Support Vector Machine algorithm, then evaluated changes in LST on cropland, forest, water surface, and impervious surface areas. The results showed that in places with dense vegetation cover, LST value was low, whereas when moving to areas with low density of vegetation and residential areas, industrial parks,… LST value gradually increased. In general, changes in LULC are important factors that cause LST to increase or decrease, thereby suggesting solutions to minimize high-temperature areas
