Introduction Urban land use and its spatial distribution is one of the important factors for optimal and optimal use of urban spaces. In the meantime, how land use is in keeping with the trend of the city's evolutionary history and the spatial changes made with the body of the city are among the factors that the city has acquired its landscape and landscape over time. In fact, land use can be considered the spatial aspect of all human activities on earth to meet its material and cultural needs. The ultimate goal of land use planning is to create a kind of (ecological balance) and (social justice) development and development of the city and it must also address human quality goals such as aesthetic perception, sense of spatial identity and sense of belonging to the environment. The answer is that, ultimately, these are the factors that provide the ground for the "comfort" and "satisfaction" of citizens. Given the inadequacy and limitation of quantitative standards in the last two or three decades, indicators of quality of life, social welfare, general comfort, conservation of natural and historical resources must be taken into account.
Methodology The type of applied research is the descriptive-analytical method used in the survey and the gis tool. The statistical population of this study consisted of 22 districts of Tehran (4 districts with 9 neighborhoods). In line with the process of measuring the development of health services after collecting raw data from the Deputy of Health and Shahid Beheshti University of Health and Tehran Health Site and the results of the latest census of population and housing in Iran. Action has been taken and then the health inequalities are available by downloading from health centers. The raw data, which were prepared in different ways, were then classified and combined according to the needs of the categorized research, and then processed and analyzed through software such as Arc GIS and Excel, etc. In fact, in relation to Tehran District 22, after gathering the desired information, then the data were entered into the database and stored in different information layers and after analysis using overlay model, the location indices for establishing new health centers were determined and finally The designation of new centers for the construction of future appropriate health centers was undertaken. Two descriptive and descriptive field methods were used to obtain the required data. Steps of doing spatial studies, including surveying and preparing the land use map of District 22 of Tehran, reviewing existing urban maps, especially maps that were digitized on a scale of 1.200, field observation through which 8 primary indices (type of ownership, location, area) M2, neighborhood, number and percentage of neighborhoods, area and percentage of neighborhoods, on the one hand, and other types of uses (educational, commercial, sports, cultural, religious, units).
Results and Discussion
Nowadays, urban land use planning, as urban land use planning, is how to use, distribute, conserve land, spatial organization, spatial planning of urban activities and functions based on the needs and needs of the urban community and the urban planning core that categorizes and types of land use. Locates. What matters in this area is how to determine the optimal allocation and allocation for different uses and uses of life. In other words, the purpose of urban land use system, determining the type of land use in the city, guiding the urban spatial organization, determining the construction. Therefore, knowledge of urban land use patterns and models is essential for urban planners in order to regulate optimal land use. Therefore, the research findings showed that the number of health centers in Eight with 7 centers, four with 4 centers, and Three with 4 centers were ranked 1 to 3 and neighborhoods 6 and 9 with no health center. On the other hand, among the incompatible land uses, only 10 incompatible land uses are adjacent to the Eram Surgery Hospital, with residential use having 98.32% highest compatibility and commercial, cultural, religious and gasoline use with 0.015% being the least incompatible land use. and among the compatibility users, there are only 11 types of clinic-friendly uses, with the highest neighborhood being Degree Street with 31.93%, waste land 19.32% and public green space with 16.8% next and the least neighborhood. 0.84% public open, compatible. Also for radiographic access of health centers in functional radius analysis (1000 to 1500 m) in map (3), the results showed that radiographic use both in terms of number and radius of access to health centers with radius of 1500 m equilibrium status.
Conclusion
On the one hand, the findings of the study indicate a large disparity between urban neighborhoods in terms of the extent to which health indicators are available, and on the other hand, a lack of proper and well-planned hygienic land use planning in the 22nd district of Tehran and a spatial disequilibrium. and the accessibility index for all areas is not the same. It is necessary to pay attention to reducing the differences between urban health services. Therefore, in order to improve the distribution and distribution status of the clinic and the per capita of different urban neighborhoods, practical strategies for outsourcing.
