The purpose of this article is to investigate the effectiveness of the urban spatial organization approach and metropolitan areas of Iran based on changes in modern economic structures with emphasis on the metropolis of Tabriz. Because it seems that in the conditions of incompatibility of the spatial structure of metropolises, which are the cause of growth of national economies and enhance the international and global position of countries, with the role and function commensurate with the changing structures of the world economy, the problem of physical contradictions They will face and the way to globalization of the country through big cities will be blocked for them.

In this article, the basic principles for urban and regional spatial planning and the need to pay attention to the role and position of metropolises using the opinions and theories of experts in this field such as Daniel Bell, Fritz Ma Klopp, Alvin Toffler, Frank & Bed, Youngji Masuda, Simon Nora, Alan Monk, Mark Avery Pourat and Manuel Castells, who have views related to the information society, have been studied and the theoretical foundations of Tabriz metropolitan development plans have been compared.

 In terms of methodology, data collection and analysis has been descriptive and secondary analysis, which has advanced the research work under the branches of survey and case study.Also, in the analysis of this article, content analysis, comparative and test methods have been used.

The main findings of the article are the characteristics of metropolitan space organization based on the requirements of the information society and the use of information paradigm in compiling the ideas and documents of urban development plans and regions of Tabriz metropolis that have been prepared since 1989.

Random urban growth and land use changes will lead to urban development.Changes in land use in urban areas typically reflect the economic development and population growth. Parsabad city as a newly established city in recent years has seen rapid physical development as well. This expansion causes changes in land use and land around of the city. The research method is Descriptive-analytical, Data collection method Documentary and field method, tools used in this research is ENVI 5, IDRISI SELVA, ARC GIS software. In this study in order to, analysis of urban development and land use changes during different periods of remote sensing data and Landsat sensor TM in 1989 satellite images, the ETM 2002 Landsat, Landsat 8 (OLI) 2015 on June months has been used. assessment of urban development scale and different land use areas and analysis of changes in the crosstab function respectively. The results showed that build-up urban land area has expanded from 278 hectares in 1989 to 560 hectares in 2002 and 820 hectares in the 2015 year. The amount of urban development play a major role at the Loss of other lands, especially barren and farm lands, subsequently led to declination of barren land area from 1059 hectares in 1989 to 192 hectares in 2015.

Any kind of form is formed within the geographical perspectives associated with social processes . Ecological and spatial segregation within the cities have different reasons, including social, racial and economic specifications. symbolic consumerism which is a kind of lifestyle , makes the people with similar tastes to gather in affluent areas of the cities and thereby creates a specific characteristic to their own living place which prevents the entry of people with different life styles in to their neighborhoods. This study aims to investigate the relationship between symbolic consumerism and ecological segregation in Tabriz city in two separate neighborhoods of Kooye Ferdovs and Valiasr. The main research question is that "whether there is a relationship between the symbolic consumerism and ecological segregation ? The present research from the nature point of view is of quantitative research type with analytical- descriptive method which surveying method was used for finding proper answers to the questions. For statistical analysis, Pearson correlation test and for independence test of two samples, Mann-Whitney U test has been used.
Due to the nature of the research is a quantitative research is descriptive and analytical method which has been used to find answers to questions. For statistical analysis, Pearson correlation test and Mann-Whitney U test was used to test the independence of two apart. The number of the selected sample for Kooye Valiasr was 350 people and for Kooye Ferdovs was 150 people. The results relevant with correlation test shows that there exists a positive correlation with coefficient 0.623 between the symbolic consumerism and ecological segregation. The obtained results of regression analysis shows that 39% of the cause of segregation can be found in consumerism. The obtained results of the two independent samples show that although these two societies have no difference from the view point of brand loyalty and willingness to segregation but the tendency to luxury oriented and use of luxury goods and social reasons and their views and approaches toward each other is different and the same has caused that a group select Valiasr neighborhood and the other one select Ferdovs neighborhood as the brand for segregation.

Popular view of the development in the past ignorant to the distribution of special possibilities and under-constructions in different grounds in proportion with special capabilities of each region has formed present face of central cities. On the other hand، because of the problems such as savings arising from scale of possible attention and presentation of services and possibilities for each one of rural areas is not possible in action that will cause severity of communications between surrounding rural areas with central city for removing economic، social and service necessities. In present research we have tried to determine place and role of surrounding areas concerning with city and its development، with the use of environmental، economic، social and physical powers present methods which results in safe communication of surrounding areas with Shabestar. In this research، analytic method is descriptive–analytical using SWOT model، we tried to know the existing state of affairs، operations and actions and also possibilities and limitations of Shabestar and its surrounding area. Acquired results from data analysis have shown the role of surrounding areas in Shabestar development.

Nowadays the urban growth pattern of cities is growing dramatically; and current suburbs of cities will form the inseparable components of the main city in the near future. In all cities of world vertical and horizontal urban growth have been one of the most important factors noticed by urban managers and planners. Urban growth is a spatial - structural process that refers to the increased importance of towns and cities as a concentration of population within a particular economy and society. Increase in urban points as quantitative issue shows itself in the forms of increase in population of cities and development in built up area scale. The unorganized physical growth of cities is due to their physical discrete and separate development which is mostly in form of forming individual and separate parts. Hence، analysis of the current physical status، and prediction of the future development of cities due to its influence on the politics and management of city and human resources، is of great importance. Regarding the numerous factors affecting the inharmonic physical urban growth، the present article has investigated the rate of urban horizontal growth from two aspects of area and direction. The research method in this article is analytical- comparative and with respect to the evolution of the physical- spatial pattern of Tabriz metropolitan in the 1956-2006 period. Shannon’s Entropy model is utilized for evaluation of the rate of the urban horizontal growth diversity. In order to use this model first we draw the complete and detailed plan of Tabriz city in concentric buffers with width of one kilometer between years 1956-2006 using Auto Cad software and the physical gravity center of Tabriz city which is the same center of cultural- historical part has been considered as basis for buffering modulation، and Sectoral- Geographical model is used for specification of urban growth directions.. In the next phase center of city gravity has drawn in the form of circle with determined diameter and the center of this circle was considered as basis for modulation of geographical sectors and sectoral buffering in 12 geographic directions. The attained results of analyzing the research findings has shown that the sprawl growth and diversity of inharmonic development has occurred in Tabriz metropolitan. The maximum of this rate has happened on the year 1996 and directions of horizontal urban growth are completely coincided on the margins of main connection corridors of city.

House as one of the humans’ essential needs, is regarded as one of the economic and sociological problems. Residential problems can be more in the increasing prices and its rents like spectially in the metropolitan region of Iran. Other large cities Tabriz have some problems such as population density, the rise in the price of land, settlement and its rent. These problems create much difficulties for the low income people, in other cases it causes the establishment of new buildings in outskirts and their accumulation inside or outside the city that generally have some affects in the spatial – structural expansion. Therefor, it is essential to use proper politics in Tabriz metropolitan housing to decrease the deficits and supply the future needs.Tabriz metropolitan structural development has followed the dwelling and land market conditions, rises Population growth has strongly changed the dwelling land markets and city spatial-structure.New residential building numbers or the buildings under construction follow factors such as land price, base–land, and rent price. Three floored or higher residential buildings are crowded most in places that land and dwelling prices and also rent prices has been higher. City space-form indexes change following the changes in land base prices and residential rent prices.

Tabriz megalopolis in its historical growth, has disturbed its surroundingaewas. The City in its historical development has never been dependant on any parish. Therefore every parish has been self reliant. Current form of Tabriz has occupied its natural position and is currently changing in quality as one of the Iran,s big cities. Nowadays knowing a city without understanding the views, potentials and its definitions is not possible. In other words, one of the reasons for creation of the crisis in city manegment, is that city potentials and its era is not well understood.
