The physical development of cities is a dynamic and continuous process during which the physical limits of cities and their physical spaces increase in horizontal and vertical directions in terms of quantity and quality, and if this process is fast and unplanned, it will not lead to a suitable physical combination of urban spaces. It will make urban systems face many problems. Land use as a main component in the management of natural resources requires environmental changes and a dynamic and effective factor on living conditions. The agricultural lands to urban and industrial uses and its economic and environmental consequences is one of the problems and difficulties of urban planners. It is faced with the growth and physical development of cities and the change of uses in the city. In this research, the changes in land uses were investigated with the aim of investigating and evaluating the physical development process of Astara city and the changes that occurred in its land uses in 2038. For this purpose, the Landsat satellite images of 2003 and 2021 and TM and OLI sensors were used to extract the land use map of the area, then the land use classification was done as well as the prediction of changes for 2038. The results indicated that the agricultural land has decreased by 151.11 hectares compared to 2003 and has changed, on the other hand, the built-up land has increased by 162.27 hectares compared to 2003 and has increased in size.The amount of changes in built-up land for 2021 is more than agricultural land for 2021. Built-up use will be associated with the growth of 118.08 hectares for 2038, which will have the largest change with growth, and also the city of Astara between 2003 and 2021 has grown more towards the west of the city.
