The Relationship of Different Land Uses with Land Surface Temperature based on Spatial Correlation (Moran) Analysis Using Landsat 8 Satellite Images (OLI)(Case Study: Ardebil City)

In this research, the relationship between land use and land surface temperature and spatial correlation in Ardebil city using Moran index has been investigated. For this purpose, Landsat 8 satellite imagery (OLI) was used from 2015 to 2018. Initially, the relevant images were taken and the necessary pre-processing was applied. Then the classification was made using the object-oriented method and the nearest neighboring algorithm and the surface temperature was extracted by the algorithm (SW). The results showed that the temperature in the urban areas was 43 ° C and 45 ° C in 2015 and 2018, respectively, due to the absorption of heat and urban pollution. The use of water was 35 ° C in 2015, and 37 ° C in 2018, that eliminates more heat from the water and has a lower temperature. The results also showed a strong relationship between land use and temperature. Finally, Hot Spot Analysis was used for hot and cold clusters of Ardebil thermal islands. The analysis of spatial correlation with global Moron indexes showed that the surface temperature of Ardabil has a spatial structure or, in other words, the surface temperature of the earth is distributed in cluster form. Hot Spot Analysis has been a clear confirmation of the concentration and clustering of the thermal islands of Ardabil in space with increasing period of time.
