- Abstract
- Many factors are involved in urban heat island development such as lack of urban green spaces, improper choice of building materials, air pollution, densification, and other human activities. The aim of this research was to quantify the effects of land use/land cover (LU/LC) changes on urban land surface temperature (LST) during a 25-year period (1993-2018) for the semiarid Shiraz City in southern Iran using Landsat data (TM, ETM+, and OLI/TIRS) and machine learning algorithms. Five main LU/LC classes such as orchard, vegetation, bare surface, asphalt cover, and built-up areas were identified using a support vector machine algorithm. Landsat images were used to retrieve normalized difference vegetation index (NDVI) and normalized... (More)
- Many factors are involved in urban heat island development such as lack of urban green spaces, improper choice of building materials, air pollution, densification, and other human activities. The aim of this research was to quantify the effects of land use/land cover (LU/LC) changes on urban land surface temperature (LST) during a 25-year period (1993-2018) for the semiarid Shiraz City in southern Iran using Landsat data (TM, ETM+, and OLI/TIRS) and machine learning algorithms. Five main LU/LC classes such as orchard, vegetation, bare surface, asphalt cover, and built-up areas were identified using a support vector machine algorithm. Landsat images were used to retrieve normalized difference vegetation index (NDVI) and normalized difference built-up index (NDBI). The LST and linear regression analysis were used to quantify the relationship between NDVI and NDBI. The results showed that the mean LST over the entire study domain increased considerably between 1993 and 2018, due to urbanization, decrease of green areas, increasing industrial areas, and other human activities. Built-up areas increased considerably by 25.8% from 80 to 100.6 km2 between 1993 and 2018, while vegetation cover decreased dramatically by 69.3%. Mean LST increased from 38.4 to 40.2°C during the 25-year period with a significant increase of 3.9°C between 2013 and 2018. In addition, the Urban heat island Ratio Index (URI) displayed a substantial upward trend during the 25-year period. (Less)
