Evaluating the relationship between land use planning and the formation of urban heat islands (Case Study: Meshginshahr City)
Population growth and urban development have made use of much of the urban land, especially agricultural lands and gardens, for residential, industrial, and transportation uses. This use changes lead to increased pollution and degradation of the environment and above all the earth's surface temperature has increased.
This study investigates the relationship between land use and thermal islands in Meshginshahr over the 1984, 1999 and 2020 time periods.
The research method is applied and research in nature. To achieve the goal of the research, after radiometric and atmospheric processing of the images, land surface temperature (LST) and vegetation index (NDVI) were calculated. Then, using the error matrix method, the accuracy and precision of kappa for production maps were evaluated.
Studied Areas:
The geographical area of this research is MeshginShahr city.
The findings indicate that Maps of the heat island show that in 1984 the minimum temperature is 22 and the maximum temperature is 43 ° C. While this situation has been increasing in 2020, the minimum temperature is 29 and the maximum temperature is 63 ° C.
The results of the relationship between land surface temperature and land use changes show that the highest land surface temperature is related to urban construction lands and this is a result of reduced vegetation cover and increased impermeable levels. Also, the study of the spatial distribution changes of the surface temperature of the island and the thermal island showed that with the disappearance of vegetation inside and around the city the cool temperature class replaced the warm temperature class.
