Since the beginning of the present century, the changes in urbanization and its physical transformations have had unfavorable consequences on the structure of the Iranian city, so that the current city, without any attention to its initial construction and organization, has been characterized by disruption, irregular (uneven) development and Socio-economic inequalities. Therefore, the study of changes in the spatial and physical structure of urban environments and their orientation towards harmony and spatial equilibrium is necessary in various aspects of physical, social and economic and preventing spatial instability and inequality.Since it is difficult and impossible to understand the structure and frame of cities based on the analysis of all parts of the city. therefore, analyzing the spatial structure of cities in relation to urban development pattern needs to be able to respond to these spatial spatial complexities and help to understand the structure and spatial structure of modern cities .of theories and methods that study the structure and configuration of urban spac is space layout theory. based on this theory, the city structure and basics.

In this study, the spatial analysis of building violations in the period 93-1388 was arranged. Research methods analytical and TvshAy it is applied. The required data were collected through documentary and field studies. shown, therefore, the sample size is calculated with Cochran formula and 210 people for your special infringement cases referred to the Commission NmvdhAnd the material 100 municipalities, were selected by simple random sampling and questionnaire Mhqq made, information is collected and analyzed. The results show that in the period studied, the building violations has been increasing. On the other hand, building violations in the North and East and West MhdvdhHay the outskirts of the city, including sectors that are in the path of urban development, urban and horizontal expansion led to PrakndhRvyy. Also, the opinions issued by the Commission of Article 100 of the present study indicate that the most verdict in the municipal building violations, fines (up 80 percent) were by offenders.

The urban sustainable development is economic efficiency, social justice and environmental preservation so one of the its important conditions is utilization from urban land, otherwise cities suffer from urban sprawl. So far, several models are presented for understanding the form of city and its dispersion measure. This research attempts to analyze urban spraw lof Tehran by different models such as urban density, the quartile distribution, temperature distribution, balance, concentration and temperature Holdrn model in different decades, and then considers the impact of government programs for different factors of urban sprawl. Reslts showed that with the lack of efficient management of land and illegal discrimination in Tehran there is urban sprael. Therefore, according to the principles of sustainable urban development Tehran can push toward sustainability. But, policies can control further spread of this phenomenon in Tehran and in all cities of the country.

Urbanگستردگی شهری نوعی الگوی رشد شهر بدون توجه به عواقب و اثرات اقتصادی، اجتماعی و محیطی آن است. sprawl is an urban growth patterns regardless of the consequences and economic, social and environmental effects. This exterior growth of the city belongs to the type of urban development that in critics view causes the loss of agricultural land, destruction of open and green spaces, energy waste and changes of land use. There areروش های متعددی برای آشکارسازی تغییرات یک منطقه با استفاده از تصاویر ماهواره ای وجود دارد که هر کدام دارای مزایا و محدودیت هایی هستند. several methods for detecting changes in a region by using satellite imagery; each one having both advantages and limitations. روش فازی مبتنی بر شدت انطباق یکی از این روش ها اFuzzy ARTMAP method of compliance is one of these methods. هدف اصلی از این مقاله توصیف آشکارسازی تغییرات کاربری اراضی در شهر ارومیه در طی یک دوره 27 ساله استThe main purpose of this article is describing land use change detection in Urmia city over a period of 27 years. For this purpose TM sensor of Landsat satellite in the period of 1984-2011was selected. پس از زمین مرجع کردن تصاویر با استفاده از روش فازی به طبقه بندی After referencing images by using Fuzzy ARTMAP classification method (CrosstabCross Tab) تغییرات کاربری اراضی و چگونگی گسترش شهری پرداخته شده است؛ و با استفاده از روش ترکیبی زنجیره های مارکوف و سلول های خودکار گستردگی شهری برای سال 1400 پیش بینی شده است.) land use changes and how the sprawl city were classified and urban sprawl was predicted for the year 1400 by using Markov chains and a combination of cellular automate. نتایج نشان می دهد طی این دوره 17188.56 از اراضی شهر ارومیه تغییر کاربری داده است؛ که بیش ترین تغییر کاربری اراضی در اراضی کشاورزی آبی صورت گرفته استThe results show that 17188.56 acres of land has been changed during this period in Urmia and most of land use changes have occurred on irrigated agricultural lands. 7672.41 هکتار از اراضی کشاورزی آبی کاسته شده اس7672.41 acres of irrigated agricultural land has been declined. The sبررسی ها نشان می دهد در سال 1400 در حدود 2408.55 هکتار به اراضی ساخته شده اضافه خواهد گردیدstudy show that in the year 1400 approximately 2408.55 acres will add to built-in land; which may cause change in land use in Urmia city and instability in the optimal distribution of services and access for city residents.

Urban spatial growth and its patterns is one of the most important issues in urban planning. During the time, the patterns of spatial distributions which are called urban form are changing because of urban dynamics. Urban sprawl is one of the most unstable forms the cities have ever experienced. The city of Mashhad as the second metropolis of Iran and the case study of this research is not exceted of these problems. Various methods such as aerial photographs, maps of the organizations, soil and topographic maps, GIS and SPSS software are used in this research. The result of survey showed a rapid and unplanned sprawl growth has happened for the Mashhad city in the recent decades (1956-2006) that have had some adverse effects on soil resources.
The results show from 1956 to 2006 around 27747.8 hectares of Mashhad suburb lands from different classes were changed into urban landuse for good. Actually, this rapid and unplanned urban growth of Mashhad has destroyed 10,288 ha (37 percent) in class I, 6233 ha (22%) in class III, 9089 ha (33%) in Class IV and 2,147 ha (7.7 percent) in Class VI.
