    The city is develops and flourishes and changes in the history and its appearance changes due to the influence of different events. These changes are different in different times. When the city is growing, developing, making new texts with saving last physics and updating with new needs, we can say this nice city should use a logical connection between ancient text and safe the identity of city. Saving and maintaining ancient spaces without changes is impossible. In this research it is intended to find the reasons for slumpingof Babolcity in the center and ancient areas and providing ways for the revitalization to change this position.This research uses SPSS and SWOTsoftware. The result research shows that the insufficient income,temporary jobs and plans are the most important reasons for slumpingthe city in this area. As the result of the study, some solutions are provided.

    Analyzing the indicators, determining the effective factors in levels of development and leveling using statistical methods help planners to gain precise plans for a balanced sustainable development based on the analysis of main components.The purpose of this paper is to investigate how Isfahan’ counties achieve the development indicators in order to determine the regional inequality rates in these counties based on the statistics of 1385. The statistical population contains 21 counties of Isfahan Province which are ranked based on 27 indicators. To do so, the indicators of the study are reduced to 5 factors using factor analysis and are presented in a combined form of meaningful factors.Based on the findings of the research, the percentage of the portion of each factor in the development of Province’ counties was specified and also using Morris index, counties were ranked into 5 categories (very privileged, privileged, middle, deprived, very deprived), and the place of each county in the development levels was determined.The leveling results from Morris Index show that 4 counties, which are Naien, Aran and Bidgol, Kashan, and Isfahan, are at highly-privileged level andArdestan, Golpayegan, Tiran and Crohn, Khansar, Khomeini Shahr, Natanz are at the second or privileged level andShahreza Najaf Abad, Borkhar and mymeh, Mobarakeh, Semirom are at the middle level counties. Deprived Counties include Chadegan, FelavarjanSemirom-e- Sofla, Fereidan, Lenjan and at the fifth level is the only highly deprived county, Freydounshahr.In order to determine the homogenous counties, cluster sampling method was applied and the result of this leveling was compared with the leveling made using Morris index. Finally, by making a regression relation among the effective factors and the development rate, factors which have the first and second priority in increasing the development level of the counties have been suggested.

    One of the problems of big cities is the growth and expansion of informal settlements around and within the cities. These settlements absorb populationthat are looking for accessing to services, facilities and relieving of poverty following the conflict among urban _ rural, rich and poor communities. Due to the Inability to provide housing, they are stopped behind the invisible walls of the city. Shiraz as the fifth largest city in Iran is currently experiencing growth’s informal settlements in its margins and center.In this paper, using questionnaires we have extracted physical, economic and social features in three informal settlements in the southwest and southeast fringe and city center. Then this information has been analyzed using of SPSS Vesion16. The Kruskal - Wallis test and the Median were used to show the differences between the three settlements, which represent the differences between three quarters in these variables: residential unit area, density of people in the house, number of rooms, age of building, satisfaction with the quality of house, satisfaction with living in the neighborhood, living facilities, monthly costs and incomes.In addition to the evaluated variables of satisfaction with quality of house, satisfaction with living in the neighborhood in three settlements was also investigated.As the result, the Spearman correlation test has shown a significant relationship between the satisfaction with living in neighborhoods and the satisfaction with the house.

    Increasing urban population and urban developmenthad increased the production of atomicwaste. Furthermore, the many other relations of modern life and the machine make a serious approach to urban management which in return it has influences on waste storage and disposal and the eradication of urban environmental products. This will turn management of these waste materials a majorconcern. According to Zanjan Cit’s Municipal Services the daily average of 600 tons of waste materialsis produced in this city. Among the various methods of waste disposal to heaping,the most important ways in which Zanjan urban management inrecent years has reliedon,is the use of this bury site. Problems such as with drawal of the leachate, soil pollution, odor, fire, etc., scattering garbage in landfills have been observed so far. In order to prevent such problems, authorities should be trying to choose the most appropriate place to bury them, these materials out of the residential areas.In this paper the AHP model was used via ARC GIS software for the zoning of land to locate the optimal solid waste landfill in Zanjan city based on 10 criteria: fault, accommodations in the city, connecting roads, stream, geology, erosion, oil pipeline, transmission lines, slope and slope direction.The result revealed optimal locations on the landfill areain the form of a certainclass of five charges. Finally, the area of 73 hectares was called the best place for the landfill for 40-year interval.

    Open space is an ill-defined concept in that it is understood differently by different people. However a variety of different authors have used a range of definitions relating to open space. This study assesses the current urban open space in English language papers published in related journals by searching electronic database of ScienceDirect. The period of analysis is limited to the articles appearing between 2000 to 2010. In order to review contemporary approaches in scientific journals, research papers published in English language journals on UOS were obtained by searching electronic database of Science Direct. Keywords used for the search were ‘open space’, ‘public open space’, ‘urban open space’, and ‘outdoor space’ and these were looked for in titles, abstracts and keywords of articles. Initially 250 articles were identified. Of these 121 papers (58.4%) were not directly related to the purpose of this survey and 129 one (51.6%) were relevant. In this sense, four categories of approaches were noticeable. These categories, included: climatic-environmental approach; hygienic-health approach; conservative-ecological approach and planning-management approach. According to our survey, Conservative & Ecological is a variable approach (37.21%). Others are Management & planning approach (28.68%), Climatic & Environmental approach (22.48%) and hygienic-health approach (11.63%) respectively. This emphasis on contemporary articles can be justified by ecological concerns within the last decay. Articles, mostly interested in conserver & supplier function of open space throw public demand and give emphasize to natural spaces in order to manage the use of open space and to shape the build environment growth direction. The results of this article indicate the increase attention to the planning- management and conservation-ecological approaches in open spaces especially from years 2007-2008, these pieces of research often consider open spaces beyond inner city spaces such as those in suburbia and rural areas. Recent priorities in research issues are the methods, models and the influences of each urban-regional planning and management decision on supplying key roles of open spaces and the most important ones, the protective role.

    During the past century,the combination of new technologies and socio-cultural behaviors on the one hand, and the preoccupation of planners about car-mobility access and meeting its demands on the other hand, had led to ignoring the pedestrian access and its required spaces in cities inducing multiple and longer intra-city trips. This trend has resulted in unpleasant socio-economic impacts as well as environmental ones, especially for city centers. Thus, from the late 1960s onward, new theories and practices of urban planning have been developed to constrain over-emphasize on car-accessibility and to regenerate the city centers. In this regard, the present research is carried out to trace the car dependency in Hamedan city planning and to investigate the feasibility of pedestrianization of city center in line whit urban regeneration. The findings indicate during the past four decades, the car-dependence pattern and over-concentration of commercial and service uses in city center, not only have caused more car trips and traffic jams, but it has created unsustainable social and ecological impacts. Overcoming these problems first requires setting aside the car-dependence pattern. Secondly, it needs provision of better pedestrian access and gradually pedestrianization of Hamedan city center streets. These will simultaneously reduce the traffic and enhance civil life.

    Both geography and literature are considered as human sciences. These two scientific fields have close links. The nature of Iran has impressed Iranian literature and poets. Mountains, rivers and streams have always been sources of inspirations. Many poets such as Ferdowsi,and Hafez have the most beautiful description of environment surrounding them. Richness of Iranian literature and diversity of features in this country have inspired the poets over centuries. In this paper it is attempted to present an interrelationship between Iranian literature and role of geographic features of a country such as Iran with a great diversity in both physical and human aspects.

    Tehran and Alborz provinces havealways been a destination of manyemigrants from other parts of the country. It is obvious that the region has reached to significant value of activity and communities’centralization; therefore,it causes many problems. Due to a distribution pattern of population, allocatingtotal facilities, proficiencies and opportunities and special political, administrative and commercial activities andattracting too many people from other parts of the country, Tehran city has encountered with demographic irregularityofpopulation distribution of its peripheral structure, hence,serious environmental problems like weather and water resources pollution. In this paper it is attempted to perform an experimental approach into cognition of susceptible regions of population establishment and also cognition of sensitive and vulnerable regions in terms of natural causes using GIS software in the mentioned region. The objective is reconnaissance of the regions that have been followed by spatial distribution of activities and communities.Therefore several layers of information have been provided and final sentences based on superposition and analyzing the information layers haveresulted. The results were prioritized in three categories called first, second and third, to establish the communities and activities; this classification shows that extensive regions of study were qualified for the favorable conditions, by adopting regional development macro policies, as extensible regions with acceptable functional roles they could perform in a national scale.Distribution pattern of sensitive and vulnerable regions specify that many of current populated points are located in these regions, and they cause plenty of existing problems. Vice versa, many regions with appropriate condition for establishment are empty and unused due to inattention to the peripheral potentials.
