Population expansion and excessive urbanization, especially after the industrial revolution, cities face problems such as lack of housing, poverty, types of pollution, traffic and Congestion, decrease in connection with nature, loss of desirable urban spaces, decrease in health level, etc. are faced. According to the needs of their cities, different countries have implemented projects using the concept of a healthy city, among which we can refer to the healthy city project. the current research is pragmatism research that has a combined approach that uses both quantitative and qualitative methods at the same time. In this research, which has a combined approach, the strategy is considered. after collecting quantitative data by questionnaire and qualitative data based on interviews and field observations, the researcher identifies the quantitative and qualitative indicators of the city of Health and the old and new fabrics of the city, then analyzes each type of data. by identifying the quantitative and qualitative indicators of the old and new fabrics, as a result by using the structural model, all of fabrics can be compared based on the indicators of the city of healthy, and based on that, the degree of enjoyment of each from these fabrics, we will measure the criteria of a healthy city. In future studies the conceptual model can be developed and be much more utilized.
