With the generalization of neoliberalization in recent decades, some changes have been made in the Third World’s cities to remove barriers to capital accumulation and capital flows. An obvious example is a change in the use of urban space. In this research, we try to present a theoretical model explaining the influential factors of the change of urban land use using the approach of the political economy of space. For this purpose, with regard to urban and global factors affecting the land use change, we presented a theoretical model of the political economy. Then, in order to design a theoretical model about influential factors on urban land use change, we combined the urban and global factors. The findings demonstrated that to propose a comprehensive explanatory model, we need to consider the internal factors for the Third World countries.

Spatial segregation in most metropolises is widely interesting issue because of their potential to foster segregation process and because of globalization impact to reinforce it. Goal of this paper is to study spatial patterns of segregation in Tehran metropolis. To examine segregation indices, we use three indices including two-group spatial segregation index, multi-group spatial segregation index and deviational ellipses respectively. The variables used for analysis from 2006 national census made by Statistics Centre of Iran and are organized in eight variables including: occupation, literacy, quality of home, area of house, family dimension, headship age, religion and ethnic status. Results show although different among variables, spatial segregation exists in Tehran. Compared with other variables, Religion and ethnicity have higher level, respectively, of two-group and multi-group spatial segregation. Despite spatial assimilation theory, religion exhibits more clustered pattern than ethnicity. Standard deviation ellipse indicates Tehran has strongly dual structure according to area of house. Also, unlike the discussed theories, increase in family size do not accompany increase in Area of house, then, sizable houses are occupied by married-couple households with few children and tend to move to North parts of the metropolis and married-couple households with more children has been deprived of ample houses and located in Northern Tehran.

Oil-based cities appeared and started to develop by oil exploration, and development relied on oil exportation, made them modern and wealthy cities, but by terminating of this non-revival resource, downfall part of life cycle of these cities, commence. Masjed Soleyman is a best sample of these cities that was a modern city with sufficient infrastructures in national scale, but by terminating of oil-resources, socio-economical aspect of city has been faced with many different problems. Therefore it is necessary to take economic sustainability of Oil-based cities into consideration and create a multi-purpose economy based on appropriate approach and urban development pattern. The main goal in this paper is to formulate optimum strategies to create variety of alternatives for the economy of sample city in the case study (Dogonbadan). This goal is set up in regards of urban sustainable development vision and based of strategic approach. The other purposes of current paper include literature development in the field of resource-based cities (especially oil-based cities) and formulating quantitative strategies and guidelines for urban planners and managers of these cities. Research methodology in this study is compilation of quantitative and qualitative methods and research has been done by profound interview, document studies and making strategic factors quantitative. Research process includes 5 steps; step 1: after data collection, the research team classifies them for using in next step; step 2: profound interviews are done with experts, managers in oil section and municipal section and experienced planners in organizations in Dogonbadan; step 3: SWOT (Strength, Weakness, Opportunity and Threat) matrix formulated by collecting data through interviews and documents studies and evaluated by analysis model; step 4: after determining the best strategies for the city, strategies converted to quantitative forms by QSPM Matrix; And finally, step 5: strategies for urban sustainable development in the city of Dogonbadan ranked. The result shows that Dogonbadan faces with strategic challenges between costs and benefits. Nevertheless the city encounters with weaknesses and threats, it has strengths and opportunities for sustainable urban development. Sustainable urban development in this city cannot be done unless by using its opportunities and taking an appropriate approach to urban planning and management. So it is necessary for Dogonbadan to take opportunities and decline the threats.
