Examining the Impacts of Urban Expansion on Spatial Patterns of Rurban Space; Case Study; Urmia City
چکیده:
Unprecedented urbanization, characterized by population shifts from rural to urban areas and urban land expansion, has occurred globally in the past few decades. Urbanization is usually associated with land use change and urban expansion. Urban expansion, as an important social phenomenon, has a clear effect on the landscape pattern, processes, and performance on a local and global scale. Therefore, urbanization is always associated with the spatial expansion of urban land, which leads to changes in the landscape pattern. Previous studies have analyzed urbanization patterns in areas with rapid urban expansion, while urban areas with low to moderate expansion have yet to be addressed, especially in developing countries such as Iran. Therefore, the current research aims to analyze the effects of urban growth on the spatial patterns of the suburban areas in Urmia. In the present study, the first set of data will be satellite images, so the satellite images of 1990, 2000, 2010, and 2020 of Urmia city were received from Landsat satellite and processed using related software. In order to achieve the goal of the research, urban expansion was quantified with two main indicators, UEDI and UEII, and then spatial criteria were used in concentric and concentric zones to examine changes in the landscape. The results show that Urmia city expanded continuously during the studied periods, and the built-up area increased proportionately to the total area, which may indicate urban growth and population increase. Also, the findings indicate that the area with high-intensity expansion is located in the middle areas of Urmia city, and the intensity of expansion has decreased significantly in the following decades compared to the first period (1990-2000). In the first decade of 1990-2000, the greatest difference and intensity of urban expansion occurred in the direction of the east and north of Urmia city. But in the next decade, the desire to expand the built lands in the southwest, west, and northwest has increased. Finally, in the decades of 2010-2020, the pattern of urban expansion has tended toward the east and northern regions, mainly due to the increase in agricultural and industrial activities. Also, the investigation of the effects of urban expansion on urban spatial patterns using geographic spatial regression showed that the spatial pattern of Urmia city can significantly intensify urban expansion.
