Abstract

The city of Sari, as one of the most populated cities in Iran, is facing the increasing growth of urbanization, which has led to many transformations in this city. The aim of the current research is the comparative analysis of the effects of vegetation on increasing thermal energy and increasing temperature in Sari city. Considering that the current research has done a comparative analysis of the effects of vegetation on increasing thermal energy and increasing temperature in Sari city in three time periods from 1378 to 1398, it can be said that the community studied in this research was the local situation (temperature and vegetation cover) of Sari city. Is. Also, the data of the current research in the field of air pollutants includes Landsat and Sentinel data. The data analysis of the current research is based on the processing of Landsat and Sentinel satellite data and using ArcGIS and Terrset software. The results of the present research showed that in the above three periods, the temperature of the earth's surface has increased in parallel with the reduction of vegetation in Sari city, and in 1378, with the lowest degrees Celsius from 19 to 32, it reached 23 to 41 degrees Celsius in 1398. And with the reduction of the amount of vegetation based on the constructions and the physical expansion of the city, the temperature has increased significantly. The results of the calculation of the correlation between the surface heat of Sari city areas show that there is a spatial correlation (point to point) of 0.47 between the surface heat energy of Sari city areas in 1378 and 1398, which means that 0.053 of the area of Sari city during The temperature pattern has changed in the last two decades.
