Land surface temperature is one of the important parameters for determining the energy balance of the earth, weather studies and the environment. On the other hand, rapid population growth, urban development, environmental pollution, climate change, air inversion, and environmental activities, such as the creation of green spaces on the other, are factors that affect the quality of human environments. The temperature of the air and the surface temperature of the earth are indicators that are increasing in importance. The present study was conducted to investigate the role of geographic components in the thermal islands of Mashhad. For this purpose, the ETM+ satellite images of the LANDSAT7 satellite were loaded for July 2012, and then vegetation subtraction indices, normal vegetation indices, and surface temperature were extracted. The results of this study showed that the relationship between the temperature of the earth's surface and the vegetation cover in most regions with high temperatures (from 36 to 43 degrees) or thermal islets corresponding to open and inland areas, mainly due to the formation of thermal islands, vegetation poverty, and Buildings are urban. There was also a strong direct and strong correlation between surface temperature (LST) with urban levels and a strong reverse correlation between NDVI and surface temperature in the holy city of Mashhad
