Abstract

In recent years, the rapid growth and expansion of urbanization and the rapid increase in urban population have created countless problems for cities, including the destruction of the urban environment, the lack of proper access of citizens to urban services, the existence of urban uses incompatible with other uses, lack of social justice, etc. As a result of the need to pay attention to urban planning and management, the purpose of this research is to investigate the urban development of Bandar Abbas in Deheh (2001-2020) using remote sensing technology and satellite images to prepare land use maps for the years 2001 and 2020 from satellite images. Landsat ETM7 and OLS8 were used. They were classified by the supervised method (maximum similarity algorithm) in 5 land use classes (urban area, gardens and vegetation and barren land, pastures, water). The results of the research show that the area of agricultural lands and gardens decreased by 137,900 and 118,191 square kilometers during the years 2001 and 2020, respectively, and gave way to urban areas, which increased by 96,933 square kilometers in 2001 and 2020, and also in 2001, the area of pastures was 179,421 percent. In 2020, the area decreased by 140.686% and the area of barren lands increased by 68.483 square kilometers in 2020, and the water area of 0.324 square kilometers has had a constant trend, according to this, the land cover has undergone changes in this period.
