Today cities with the rapid growth and developed, so that the urban development process is now one of the most important issue for urban researchers. Moreover, growth of cities, for how changes in the macro level is also considered. In the present study provide a framework for mapping and analyzing patterns of predictability in the development of differences spatial scales-physical has been provided the processes of growth and expansion of Tabriz. In this paper with using of multi-temporal Landsat satellite imagery and using image processing techniques land use change trend has been evaluated in 1984-2010 with emphasis to Tabriz city growth and also with forecasting techniques such cellular automata and Markov chain Tabriz city growth would be assessment till 2021. Based on the results of this study it was found that the city of Tabriz in the size and scale of operation, respectively, Agricultural Land, pasture, water, and arid, mountainous terrain surrounding the expansion of space has its own physical. According to results of the Tabriz area of 5,768 hectares in 1984 to 11,853 hectares in 2010 and has performed with the trend will be predicted till 2021 to more than 14,312 hectares. Also in development is the tendency to develop physical-space along the eastern and western city of Tabriz is the quality of agricultural lands around the city.

This article is about the financial balance (Income-Expense) of Shahdyh municipality during years 2000-2008 and the analysis of effective factors and their effect scale in municipality functions for citizen services and finally giving solutions. The study method is descriptive-analytic. For analyzing the data's used of statistical methods of simple linear Regression coefficient and the analysis of variance. In this study, after investigating municipality income resources we distinguish that incomes arise from public charges decreases from 49.7 of total incomes between 2000 to 2008 decreases to 29.4 in 2008 and incomes from exclusive taxes from 0.7 in 2000 increases to 16.5 in 2008. Incomes from donates and wealth increases from 11.6 in 1380 to 26.9 in 2008 by the rate of 39 percent. The incomes from government helps were decreasing from 2000 to 2008 so it decreases from 12.6 in 2001 to 1.4 in 2008. Investigations show that permanent incomes were decreasing in this period and unstable incomes were increasing. So, according to city and municipality weakness points and we can say that utilizing modern urban management systems, contribution of people in management of city construction of multipurpose centers for training, amusement, cultural, artistic activities and income enhancer project definition, and partnership with private session, deletion of parallel organizations with municipality, renewing laws for reconstruction tax, development and expanding of urban services such as taxi, city sewage, etc. equal credit allocation for all budget sessions and long-term are as strategies that will help municipality in trading stable incomes and good services to citizens.

The purposes of this study were to investigate the walk ability and subscales in Saadat-Abad neighborhood and indicate that how is the walk ability status in this neighborhood according to the sustainable development and new urbanism paradigms? In this study the research method was descriptive and the method of collecting data was survey. The statistics sample in this study indicated 380 people of residents of Saadat-Abad (Case study) according to Morgan table. For collecting data on neighborhood walk ability using a self-made questionnaire which contained 30 questions about 4 subscales walk ability (amenity, Safety, Convenience, accessibility). The content and face validity of the questionnaire were confirmed by 10 dominant masters and the stability of the questionnaire were calculated 0.87 in alpha Cronbach. After collecting the questionnaires and indication of data normal distribution by Kolmogorov-Smirnov Test, for indicating the status of average of each subscale used the One-Sample T-Test and for indicating the relevance between averages used of Bounferoni -Test. After identifying the means, we considered that the walk ability subscales in Saadat-Abad neighborhood were not in a desirable condition and the analyses indicated that there was a significant difference between the observed mean and the hypothetical mean of walk ability subscales.

Today, cities are extended & management information about cities increases too. Using geographic information system (GIS) in city management is very important. This project was down in several stages: Introduction form completed for free time centers & the age of young people identified, Organs in relation with younger’s recognized, Based maps (digital & analog) produced, Square studying & truth of information investigated, Based maps in computer system created, Location of centers on geographic maps registered, Information bank produced per map. In result, located information & the names of free time centers inserted on maps. This information produced by 1:2000 resolution & 43 sheet maps in A0 sheet paper with 450 spend free time centers. Described information includes three fields with 1350 boxes & this title: location name, kind of activity & location address. Results was shown that in some regions, such as 2000 area or Allahoakbar hill the number & diversity of free time center in relation density of population, are lower than standard & in central area of the city such as around of Bargh circle and around of darai building the density of them is high. Number of these centers is 4-8 times of areas that do not have good facilities. With analysis in diversity of centers this amount will be increase to 11 times. Thus distribution these centers with considering kind of activity in all of areas is not balance. In some areas there are no enough young people to go centers and this shows that this analysis is correct. This free time center information will help to distribute normally in future. It is very important in cultural management & intelligence extended of Bandar Abbas city. Using from GIS technology for balance distribution of culture centers is advised for other project.

One of the significant characteristics of urbanization process in Iran is the rapid, physical and scattered development of cities especially within some recent decades. This development has some disadvantages such as wasting environmental resources and urban lands Safa Shar is one of the cities which was hurt a lot because of rapid growth and urban sprawl. The most important hurts were destroying agricultural gardening lands in the border of this city. This research is going to explain this phenomenon by using some related quality indicators. Also, it is investigating the effect of its environmental biology on destroying agricultural lands and as a result the change in the climate of Safa Shahr. This research is done by analytic-descriptive method and by referring to documentary-library studies, also, by using GIS in preparing the necessary maps. The most important founding’s of this research are as follows: Safa Shahr has had the sprawl growth during recent decades and this change has caused destroying 78 hectares of agricultural land during 1369-1381. In addition, during this period the amount of agricultural lands, that is , very good, good and average classes of this city decreased a lot and instead the area of weak lands class increased considerably finally, the area related to very cold and cold classes of temperature decreased and instead the area of warm and very hot classes of temperature increase.

To consider air pollution in Isfahan, Pollutant Standard Index (PSI) data of 3 stations of pollution quality survey (Laleh squar, Azadi and Bozorgmehr) during 1384-86 are used. Approach in this research has been environmental to circulation. Hence to identify the effect and relation of daily extreme PSI, days included a number over 120 are chosen during mentioned statistical course. So maps of middle atmosphere patterns (500hectopascal) are extracted from NCEP/NCAP climatic station for the coordinates of 10o to 70o E and 10o to 70o N. The result of this study represents that circulation patterns of middle atmosphere have significant effect on air pollution in Isfahan. A source region of extensive high pressures is observed over a large part of Iran special mentioned area. This causes stability and particles density in Isfahan.

Studying differences among several districts in the province in the point of view of their prosperity rate of several factors in order to know about their development or deprivation meter decrease in regional inequalities and regulating appropriate programs based on conditions and potentialities of each district is an inevitable necessity. This study, using Morris method, focuses on determining development degree of cities of Isfahan province in the field of major indices of agriculture and its main purpose is to find the gap scale among cities and the sort of their deprivation. Statistical society of this study includes all cities of the province. 14 scales used in this study, derived from 2003 general agricultural census and 2006 population and residence census, mostly emphasize on the source management of the cities in the agricultural field. Principal results of the study indicate that the gap and inequality among cities is profound and its proportion is up to 14.6 times. Esfahan, Falavarjan and Najafabad are in the group of developed cities but Khansaar, Chadegan and Fereydonshahr are the most deprived ones in the province.
