Urban Growth and Its Influencing Factors
Subject Areas :Keywords: Urban Growth, Remote Sensing, Logistic Regression, Factor Ecology, Tehran Metropolis.,
Abstract :
The urbanization process and urban growth in different parts of the world result from the interconnected interactions between factors and various socio-economic, political, technological, geographical, cultural, global and local issues. Accordingly, identifying the driving and shaping factors of the growth of cities is vital for urban planning and sustainable development, especially in developing countries, which is used as a means of predicting future trends, controlling and guiding the growth of the city, organizing the future development of the city and eventually efficiently and purposefully managing the city. The main objective of this study is to identify the driving and shaping factors of the biophysical and socio-economic growth of Tehran metropolis. In order to achieve this goal, five main stages are taken into consideration, including the production of land use maps, land cover to study the land use spatial-temporal changes, land cover in Tehran and its surrounding areas using satellite images, identifying driving factors of urban growth using logistic regression, using a factor ecology approach to investigate the human factors effective on Tehran landscape, calculating spatial metrics for quantization of the structure and characteristics of the landscape pattern in Tehran metropolis using Fragstatas software and investigating the relationship between urban growth pattern and social areas using multivariate regression. The results indicate that the distance from the roads and the commercial center of Tehran in the period 2000 to 2014 is the most significant biophysical factor shaping the growth pattern of Tehran metropolis, and among the obtained five socioeconomic components, the population density and employment components have the most effect on urban growth pattern in Tehran metropolis.
