Explaining the relationship between space and social inequality depends on a deep understanding of the nature of space which implies spatial segregation, and how the different levels of per capita green space in urban areas. The aim of this study is to test the hypothesis that the distribution of green space use is not balanced among areas of Zanjan. Because the lack of central justice in the planning that has been done in the city has caused inequality in the amount of access to urban green space uses. The need to revise the managerial approach to more balanced distribution in urban areas of Zanjan increases. In this regard, the present study has been conducted for statistical analysis of all urban green spaces that are distributed in Zanjan. The results of these analyzes confirm the fact that the distribution of green spaces in the city of Zanjan. It has not been able to estimate equality of opportunity for all citizens because in the neighborhoods of the city, the amount of green space is not the same. Therefore, due to the significant difference in the urban areas of Zanjan in accessing the use of green space, urban management requires the creation, development and redistribution of green spaces and parks based on the needs of low-income areas.

Urban green space is one of the land uses that its distribution across the city is crucially important. Ardabil can be considered as a city with an inappropriate distribution of green space. The allocated green space per capita in Ardabil is 7.3 square meters. This figure is quite far from the indices determined by the United Nations Environment Organization which considers 20 to 25 square meters for each person. The present study was aimed at analyzing 44 neighborhoods of Ardabil city based on 11 selected indicators of green space availability set by experts. Based on type, the present study is an applied research with a descriptive-analytical method. The required data was obtained from the parks and green space organization of Ardabil in 2015 as well as through a field study. Then, in order to rank all 44 neighborhoods of Ardabil city according to their existing green spaces we have applied the Copeland model to integrate several multi-criteria decision-making models including TOPSIS, VIKOR, ELECTERE, and SAW. As a result, all neighborhoods of Ardabil were grouped into four categories namely: enjoyed, semi-enjoyed, deprived, and very deprived. As seven neighborhoods of the city lacked any kinds of green space, and most of the other neighborhoods fall in the deprived category, it can be said that the distribution of urban green space in Ardabil is an unbalanced distribution.

Urban land use and its location has always been of interesting topics to scholars of the city and urban planning. So that the scholars always have tried to pay attention to base and surroundings proximity, compatibility and incompatibilities, utility and other factors, in location allocation of urban land uses. With the arrival of the computer age and development of geographic information systems, the possibility of attention to these factors and their effectiveness in the process of planning, is more than before. In this regard and in order to realization of consideration to these factors in planning, this study is trying to answer the following question, Among the areas with development potential in area, which one is more suitable for use in order to green land use? In this article which is applied in terms of purpose and is descriptive analytical in terms, of method, land-use suitability analysis, linear combination and Delphi methods, have been used. The finding of this article that obtained from overlaying analytical compatibility maps, the value of land, land ownership, functional radius, proximity to roads, passive defense, and crisis management and natural and geographical factors of Arak, indicate that, which one of the lands with development potential in Arak, is more suitable for use in order to green land uses. Also the results of this article showed that, the combination of multi criteria location allocation based on geographic information system and Delphi jury method, can be used as decision support system of location allocation of green land use and provide acceptable results.

Due to population growth and increasing pollution in the urban environment, it is increasingly vital role of green spaces.Green space as a natural filter to reduce environmental pollution and to ensure that the relative range of individual and social health of city residents and the environment is relaxed. Due to the critical parameters, the quantity and quality of urban green space should be proportional to the physical size of the city (roads and buildings) and social needs (leisure and health needs) come, to live as green space, environmental efficiency is constant. So should develop urban green space to remain stable, according to local climatic characteristics of cognitive and local elections to be considered. For this reason, the aim of this paper is to study the evaluate the user state landscaping Eslamshahr of the model is strategic swot. On the basis of field studies and surveys of experts to collect and identify a list of strengths, weaknesses, opportunities and threats were addressed, and to deal with their strengths and weaknesses, opportunities and threats mutually Aggressive. The results show that at present, the per capita use of existing green space for the residents of this town is not up to standard Eslamshahr.

Green space as one of the most important elements of life and sustainability of city، in case of considering environmental standards and its proper distribution، regarding factors including population، density، and area has crucial and positive effect on the life quality and joyance of people. But at present، a lot of small and large cities of Iran faced with limitation and inappropriate distribution of green spaces، which such condition causes the dissatisfaction and gradual decrease of life quality and health of people. The city of Qom as one of the large cities of Iran، regarding the increasing population and physical growth، requires a desirable urban green space. this research aimed to investigate and analyze the green space use and its per capita in the most populated area of the city (district 1) and presenting appropriate recommendations in line with creating balance in socio-physical structure of the study area، as the subject of this research، can have a great importance. The methodology of the research is descriptive-analytical method، and the documentary and field data were collected، meanwhile 380 short and brief questionnaires have been distributed among the area residents based on Kokaran model to examine the satisfaction of the area’s citizen about the function and condition of green space. The research findings showed that the current situation of the area، its dispersion and distribution in the area in not at all compatible with the common standards specially the population and the residents of this area are faced with great problems in this regard. So that، the made calculations show that the shortage amount of green space in the area is 8337293m2. This number shows the undesirable condition of green space and its improper dispersion especially in north east part of the area which is approximately devoid of green space. Finally by recognizing the condition of the green space of the area، a proper green space per capita has been recommended based on Bahram Soltani model.

From the past to now, plants and green spaces have been one of the fundamental needs in human's life especially with relation to nature. These plants and green spaces have showed their importance in physical and spiritual human life more and more with extension of cities, urbanization and increasing pollutants level originated from human activity. The distribution of green space is one of the principles of geographical justice implementation in sustainable urban development by considering balanced population distribution. The main purpose of this study is an analysis of the position of green space in different regions of Shiraz city in relation to population distribution by considering sustainable development approach. The methodology of this study is based on functional purpose and descriptive-case nature in which we used entropy coefficient and convention Koyck model to find imbalance of population disperse in regions of Shiraz city and its direct relation with urban green space distribution. It can be referred to imbalanced urban green space in relation with population distribution in regions of Shiraz (1987-2007) based of Williamson index as one of the results of this study.

Today, with population increase and urban development of cities, the term green space and urban green space applications have been paid more attention. Many of these larger cities do not feel the need of having more green space. However, industrial development and citizens caused destructive effects of various environmental causes, have most notably been of a variety of air and noise pollution. The negatives effects of this development have, however as the most important factors, helped the development of green spaces in the cities. In this paper, an urban green space area with a look at Zahedan has been studied. Based on findings of this study, the population of 253,252 in Zahedan and a regional landscape of the existing 221,517 square meters in 1388(2009) had per capita green space around the 0.9 square meter; while, the standards of urban green space is about 15 meters per capita. Zahedan need at least 8 square meters per capita with respect to its special condition and that the existing standard with is far from the suitable recommended space. Totally Zahedan’s green space in this region consists of only 14 Parks, 4 Fields and 9 Boulevards in the center of this region and other urban areas, especially in a north and south regions where the roads are deprived of any green space. Findings derived from this study reveal the urban area population of approximately 378,376 people in the future which will be ten years from now, and with respect to the environmental conditions of the region, at least 8 square meters per capita in a city Patent of about 3027008 square green spaces in this area will be required. In other words, in ten years from now, about 2,805,491 square meters of new green space will be needed in this area, the layout and distribution can be optimized to a minimum standard of per capita urban green space.
