Abstract

Background and purpose: If sustainable urban development is considered as economic efficiency, social equality and environment protection, one major perquisite for its realization is optimization of urban land uses; otherwise the cities would suffer from sprawl or uncontrolled expansion. Various models have been proposed for understanding the City shape and its scattering measurement. Material and Methods: This work aims at calculating Tehran urban sprawl in various decades using different models including temporal analysis of urban density, quartile distribution, degree-balanced distribution, degree of aggregation and Holdern model, and its impact examines on nearby farms. Results: Findings of this work show that Tehran is shifting from concentration and gradual growth to excessive urban sprawl and rapid and uncontrolled growth. In The following, using satellite images of the years 1357 and 1385 we examines the rate of change of land use especially the quality and quantity of changes of Farmland to urban uses with using ArcGIS software. The image has converted to maps through visual processing or visual interpretation. At the end with map have obtained with using compilation and synthesis method that can show to how land use changes during the period (28 years). Discussion and Conclusions: The results of research in this section indicate that the total agricultural land in study area in 1979 was about 38952 hectares that Half of which have been eliminated in the course of 28 years 1996-2006 and have decreased directly or indirectly through urban development and reached 19. 4 thousand hectares in 2006. If the growth and development of the city continues as sprawl distribution. The same amount of land will be destroyed in the future development.
