Comparative assessment of environmental quality of the inefficient fabrics of Tehran city (Case study: The neighborhoods of Region 3 in District 17 of Tehran Municipality)

Measuring the quality of the urban living environment is the first step in managing it. The purpose of this research is to evaluate the quality of the urban environment in four neighborhoods of District 17 of Tehran Municipality as examples of inefficient fabrics in the south of Tehran. 55 indexes are used. The data of 29 indexes were obtained from statistical documents and sources, and the rest were obtained through surveys. According to Cochran's model, a sample of 378 household heads out of f 28235 households heads who are residing in the studied neighborhoods were selected randomly to answer the questions of the questionnaire. The documentary data, are adapted to the survey data in the range from 1 to 5 considering the Iranian standard ranges. The state of the quality of environment for each index is stated as a percentage of favorable conditions. Findings indicate the unfavorable state of the quality of the environment in the studied area. 11 environmental indicators show a relatively better state so they have almost 50% of favorable conditions. The physical structure in all the studied neighborhoods is lacking in terms of allocating land to public and service uses. Moghadam neighborhood shows the lowest and Boloorsazi neighborhood shows the highest environmental quality in all the dimensions. To improve the quality of the environment, it is recommended to accelerate the renovation of the urban fabric by faciliating the regulations and using the space that will be obtained from undermining the railway that passes across the neighborhoods.
