Abstract :
The decentralization of the population from the city centers and the suburbanization of the population, as well as the transfer of the activity centers (following the creation of transportation systems along with the existence of large and cheaper pieces of land around them) from the city centers to the outskirts are ongoing. The aim of the research was to investigate the pattern of growth and expansion of the city in the period 1363-1403. This qualitative study was conducted in Bushehr city and its suburbs. In this context, the change of urban and suburban areas in Bushehr city was studied using remote sensing techniques between 1985 and 2024. For this purpose, TM, 9, LANDSAT8 and TIRS/OLI satellite images (1985-1999) were used. Then, the slope files of urban areas for the years 1403 and 1363 were prepared using a digital tool in the ArcMap environment to be used for urban development comparisons. After determining the limits of urban growth, the type of urban development structure was determined and investigated. Based on the findings of the research, the structure of Bushehr city is multi-core and has 3 main cores: north (primary), west and east to south: 1- The expansion of Bushehr city in the northern part (primary core) is limited in terms of the density of buildings; 2- The greatest expansion has been in the eastern to southern part of the city; 3- The expansion in the western part is due to the morphological limitation of the city due to the sea.
