Abstract

Urbanization and urbanized areas have a significant impact on local and global climate. One of the most important its effects is surface urban thermal variations (SUTV), including Surface Urban Heat Islands (SUHI) and Surface Urban Heat Sinks (SUHS). The purpose of this study is to investigate the impacts of landscape pattern changes and the efficiency of Landscape Metrics in analyzing surface urban thermal variations in Hamadan using Landsat 8 satellite images. Having calculated Land Surface Temperature (LST), the SUHI and SUHS regions were identified, the existing land uses in these areas were classified and finally Landscape Metrics at class and landscape levels were extracted using FRAGSTATS software. The results showed that the highest temperature in the study area was seen in the areas with no vegetation cover, in other words the main component of SUHS is agriculture patch, while soil patch is the main constituent of SUHI. The relationships between LST and Landscape Metrics were also examined. LST and patch density (PD) were negatively correlated. In SUHS, in contrast to island heat areas, LST had a negative correlation with AI metrics and had a positive and significant relationship with PD metrics. The higher the consistency between land use and landscape patterns, the lower the temperature and the higher the fragmentation, the higher the temperature effect. The results indicated that Land Surface Temperature in Hamadan is not affected just by land use composition and land cover, LST in Hamadan is not only affected by the combination of land cover, but also the spatial configuration and structure of the landscape is influenced.
