چکیده مقاله :
Urban growth pattern classification comprises three types of expansion, namely horizontal or scattered expansion, intensive growth, and smart growth. This study is a practical investigation focusing on the development and assessment of the physical transformations occurring in Yazd City. The research has utilized multi-temporal Landsat satellite images from 1996, 2016, and Ester satellite 2006. The supervised classification method with the most similarity has been employed to analyse the levels of green space, urban built space, road, and barren land and track their changes. The study revealed that the size of the city did not change between 1996 and 2016, but the population density increased. However, during the same period, there was a significant 43.6% reduction in the amount of green space. According to the graph, there has been a consistent rise in urban development from 1996 to 2016. Throughout the duration of the construction period, there has been a 1.65-fold expansion in the urban area, leading to a reduction of 32% in the barren land within Yazd city. The collective evidence of modifications in Yazd city, both in terms of physical alterations and spatial expansion, indicates that the utilization of barren land within the urban setting and the elimination of gardens and reduction in green areas have led to an increase in urban spaces by a factor of 1.65.
