Determining the optimal per capita use of urban green space in designing a child-friendly city using GIS (Case study: Semnan city)

From childhood, human destiny has been intertwined with the environment and the surrounding space. Many educators believe that the personality of every human being is formed in the first 6 years of his life. On the other hand, the expansion of vertical constructions and the use of minimal space to create houses today do not give the opportunity to build yards and safe alleys for children's physical activities (such as running, playing, exercising, etc.). It is in this context that the role of public green space in the city for adults, especially children, becomes more prominent. Therefore, by examining the needs and problems that children face in urban environments, urban space designers can plan and design appropriate to provide favorable conditions for the physical, mental, emotional and social development of children and the flourishing of their talents and interests. Security and be actively present. However, the problem of lack of green space and its inappropriate distribution can be seen in many cities in Iran. One of the main reasons for this is the lack of water supply and dry air. The city of Semnan, as one of the desert cities with special climatic conditions, needs a favorable urban green space. In the present study, which is written in an applied type and based on a research-analytical method, data collection has been done in the form of documents (library) and field. A questionnaire was prepared to examine the research indicators and distributed among different sections of society. Then, using GIS and analysis, the significance coefficient was assigned to each of the indicators. Finally, according to the research formula of the study proposed by Mr. Kambiz Bahram Soltani, the proposed per capita amount for the use of green space in the city of Semnan due to unfavorable climatic conditions, 28 square meters was proposed. The result of the research shows that the city of Semnan, considering the climatic conditions, is far from the appropriate per capita research proposal. Finally, solutions to improve green space are suggested.
