In recent decades, cities have grown organically and urban areas in a short time have been several times its original size and city development has been the forms of the individual components, without planning, uncoordinated that urban sprawl pattern is the main feature. Urban Smart Growth cities were developed for deal with problems of sprawl. The case study is Maragheh city. The research method is descriptive and analytical. In this paper, the capacity of Maragheh, using the development from within the main principles of smart growth is about the sprawl, is marked. Indexes such as population density, rate of open space, building quality, access and permeability, compressibility, etc. are used. Neighborhoods with using Analytical Hierarchy presses (AHP) to prioritize and ultimately the level was estimated for each of them. Results show that in 1392 the gross population density of 59.3 persons per hectare is which is considered very low density and On the other hand there is a lot of undeveloped land, 333 hectares, Uses of unconventional urban, and the average per capita level of infrastructure per person is 162.3 square meters. With this description, using the principles of smart growth and in particular, the principle of development from within and Suitable density, Building on wasteland and etc., sprawl can be prevented the sprawl.

The growth and development pattern or city form is defined as spatial pattern of human activities. At present the city pattern is divided into two groups as horizontal or sprawl and vertical or compact. Evidences show that cities are grown unplanned in recent years and the cities' limits have expanded several times than their primary area. Thus, planners and policy makers are trying to identify the physical pattern of cities to manage and direct the city growth in line with sustainable development. Maragheh is the case study for this research which is located in the north west of the country. The research applied analytical-comparative methods to identify and assess the pattern of physical and spatial growth of the city in different periods. The quantitative models included accumulation degree (Moran and Grey), Entropy, Ginny coefficient, Heldern and density. The results show that the city has experienced a slow and compact physical and spatial growth in the past through which the start of rapid urbanization during 1355 to 1365 expanded rapidly. The area of city increased 16.5 times and this was in the form of sprawl and continued to 1385. Regarding the results of the research the compact city pattern is recommended for the change of growth pattern and approaching the urban sustainable development.
