The spatial relationship between land use /cover change on land surface temperature in Bushehr coastal area

Land surface temperature (LST) and its relationship with land use /cover change are significantly considered in environmental studies. The aim of this study was to retrieve the LST of Bushehr land and explore its spatial relationships with LULC. Landsat images of August of the summer season for three years with fifteen years time intervals were analyzed. The result showed a gradual rising (1.4 °C during 1990–2005 and 2 °C during 2005–2020) of LST during the whole period of study. The mean LST value for three study years was the lowest (30.86 °C) on green vegetation and the highest (49.07 °C) on bare land and built-up areas. The spatial distribution of NDVI and LST reflects an inverse relationship. The best (-0.97) and the least (-0.80) correlation, respectively, whereas a moderate (-0.89) correlation was noticed. This LST-NDVI correlation was strong negative (-0.80) on the vegetation surface. The LST is greatly controlled by land-use characteristics. This study can be used as a reference for land use and environmental planning on coastal land.
