The Impact of Land Use Changes on Surface Temperature Patterns in Urban Areas Case Study: Isfahan City

The expansion and development of cities and the increase of urbanization are some of the current characteristics of human societies, especially in developing countries. Density and population growth in cities have led to the expansion and development of urban areas and changes in urban land use. In this research, a remote sensing technique was used to identify the patterns and examine the spatial changes in the surface temperature in different areas of Isfahan City. Using thermal equations and a similarity centre algorithm, the temperature of the earth's surface has been calculated for the periods of 1365 to 1401. The supervised classification of the most similar method was used to evaluate the changes in the land use of the studied area, which includes built uses, gardens, vegetation, and lands without vegetation. The results of the comparison of land use between 1365 and 1401 within the scope of studies show that during the mentioned period residential use increased by 175.94 square kilometers and garden use by 74.28 km shows a decreasing trend. Also, we see a decrease of 39.03 km in the use of vegetation and a decrease of 217.75 km in the use of areas without vegetation. The results of the earth surface temperature survey show the expansion of the earth surface temperature during the study period in Isfahan city. Based on this, in the studied period, the earth's surface temperature increased in the east and southeast regions. Examining the isothermal lines shows that the temperature of the earth's surface around the city increased significantly in terms of temperature and extent.
