Extended Abstract
Today, the expansion of urbanization along with the increasing population growth and environmental pollution have created difficult conditions for the survival of human life (ostadi and et al., 1396: 329). This development and rapid urbanization of most countries in the world has caused many problems, such as the lack of proper use of all citizens for urban services (Akbari and et al., 1396: 68). The direct consequence of this increase and the over-population density in recent decades is the change in the structure of the urban landscape and natural scenery of the city, followed by a much more tangible need for urban respiration and subsequently increases the air and noise pollution in Cities have been (Yazdani and et al, 1395: 252). Expansion of change in cities has transformed urban respiratory centers, including urban green spaces, into harsh and impenetrable concrete surfaces, which is more serious in Third World countries (Shi, 2002: 18). The present study was conducted to investigate the status of parks and green spaces in 22 areas of Tehran. One of the issues in the city of Tehran is the uneven distribution of green space in different parts of the city, and in some areas, the need for recreational spaces and green spaces and the relative per capita of parks are not paid attention. Population density and the effects of excessive forces on this the texture has destroyed its environmental quality, so that the comfort and psychological security of the people living in these areas has been aggravated. In this regard, this research seeks to answer the following questions:
1. What is the position of the 22 metropolitan areas of Tehran in terms of urban green spaces?
1. How is the spatial pattern of spatial cluster spacing of urban green spaces in the 22nd metropolitan area of Tehran?

In this research, the type of research is applied and its method is descriptive-analytic. Two methods of library and documentary (Statistical Yearbook of Tehran) have been used to collect data. Based on the methodology, the research indicators are extracted from the basics and literature on urban green spaces. The geographic area studied is the metropolis of Tehran and its 22 districts based on the political divisions of 1395. Also, for analyzing data and information, entropy methods, copras multi-criteria decision-making technique, Moran's self-correlation and spatial cluster analysis of multidimensional or k-Ripley function in software ArcGIS Used. Results and discussion:

With the increase in population, especially in major cities, the importance of urban green spaces has become increasingly important. In our country, most of the big and medium-sized cities have grown without plans, and the standards for urban green spaces and other vital uses of the city have not been fundamentally allocated. The Metropolitan Tehran, as the administrative and political capital of our country, is also facing this problem. Along with other political and planning developments, the city has faced increasing growth in recent years. Maintaining the basic needs of this massive population flood in this city is one of the main concerns of urban authorities. This research was carried out with the aim of studying the spatial distribution of urban green spaces and comparing the 22 areas of Tehran with respect to 20 indicators extracted from the statistical journal and green space site in Tehran. As the findings show, parks and urban green spaces are not distributed regularly and planned in the city area. If the per capita survey of urban green space shows that 19, 20 and 21 regions of Tehran with the per capita level of 33.6, 61.3 and 19 square meters, respectively, have the highest percentage of vegetable space per capita In contrast to the 10 regions with the lowest per capita level of 1.8 and the 7th area with a per capita level of 3.7, and finally the area 8b, the per capita rate is 1.4 in the last place. . According to the approvals, the structural and strategic plan of city development (comprehensive plan of Tehran) for the urban future of Tehran in the green area to develop green spaces with a scale of urban, regional, regional and local action to provide at least 10 square meters per capita green space in Tehran with balanced distribution According to the chart above, it can be said that in most areas of the city this is not achieved and in 10 urban areas per capita green space is less than 10 square meters.. Also, the findings of this study are consistent with the research on the urbanization of urban green spaces (Case Study: Tehran's urban areas), as well as its findings suggest that the average per capita space The green gained for the areas of Tehran in 2009 is 5.9 square meters, which is approximately half the proposed per capita for Tehran (10 square meters) based on its comprehensive plan in 2007. The results of this research showed that the amount of green spaces per square meter in Tehran's 22 districts is not standard and the proposed per capita comprehensive plans in most areas are not realized. Also, the research findings of Hosseini and et al (2012) with the title of studying and analyzing the space of the park and urban green of Shiraz city are also consistent. The results of his research did not show that in addition to the lack of green space in the city of Shiraz, the distribution of green space In the nine regions it was not fair, the findings of this study showed that the distribution of green space in areas of Tehran is not fair.

The results of his research did not show that in addition to the lack of green space in the city of Shiraz, the distribution of green space In the nine regions it was not fair, the findings of this study showed that the distribution of green space in areas of Tehran is not fair.
