Persistent spaces and phenomena over time and load and become part of collective memories. In this way, paying attention to the durability of space design increases the sense of belonging to space, in this case space does not belong only to the present. Considering the importance of sustainability, the purpose of this study is to identify the factors affecting the survival of urban spaces, with emphasis on the multiplication of effective daily life in three areas of the Tabriz market (Grand mosque, Rasteh bazar, and Saheb-ol-amr square). The research method is a descriptive-analytic study used for collecting information using documentary and field (survey) method. Also, in this research, in addition to applying the qualitative method for analyzing the causes of durability in the studied areas, quantitative method of analysis of variance was used to investigate the durability of urban spaces in the studied areas. The findings of the research indicate that within the boundaries of the Grand mosque, the spirituality factor (0.376), socioeconomic and functional (0.352), in the range of Rasteh bazar of the identity factor (0.314) and within the range of Saheb-ol-amr square, the factor of spirituality (0.327) and identity (0.305) is the most important reason for the survival of the studied areas. The results also show that the various components of everyday life have oddities that, while repeated in the daily life cycle, are linear (progressive, regressive, and fixed), which in two parts are all in part and in part In general, they affect the survival and decline of spaces. In the meantime, the approaches and cultural components derived from the whole are in part like the rituals and cultures of a community, have and will have a significant impact on the survival and increase of durability of spaces. Therefore, the continuation of rituals and cultural ceremonies in the studied areas can provide a lasting space for these spaces.

Identity, as a complex concept, influenced by a variety of factors, makes one thing distinct and unique. Meanwhile, the characteristics of the environment, habits, worldview, cultural characteristics, etc., have a growing influence on the formation of these indices of identity. In other words, this study seeks to investigate the hypothesis of the difference in attitudes of inhabitants of the eastern and western parts of Mashhad towards urban identity indices and, finally, whether the distinction is observable or not? The basis of this study is based on quantitative methods that have been used for research purposes, along with qualitative methods. The output of this discussion is to achieve the identity of the city and its classification according to the purpose of the study. But in the small part, the study method is based on the use of differentiation and logistic models to show the type and level of differences between the eastern and western parts of Mashhad. Based on this, the rank of indicators of urban identity components was obtained in the form of a questionnaire in two categories of eastern regions (regions 4, 5 and 6) and western regions (including 1, 9 and 11) from the residents' perspective. The completed questionnaires were entered into the statistical database and analyzed using statistical software such as Excel and Spas. Study shoes that: 1- Regarding the formic index, studies show that variables such as high buildings, traditional architecture and natural form of place are variables that cause segregation of residents of eastern and western parts of Mashhad. 2- The results in Function indices also indicate that variables of vibrant places, places with activities, boarding times, places with different uses, and safe places are meaningful. 3- Finally, regarding the semantic indices, the effective and differentiating variables in the eastern and western regions of Mashhad, including two variables of understanding the sense of pilgrimage and understanding the characteristics of Islamic culture. Accordingly, it can be said that the attitudes of residents of the studied areas are different from those related to the sense of pilgrimage and the characteristics of Islamic culture in their. the end

In today's urban planning, the paraphrastic processes of symbolic systems in the city, which aim to show the social and cultural meaning of the physical environment, have received less attention, and most urban contexts, regardless of significant and identifiable differences and similarities and the hidden values in the context and the patterns of traditional urban planning and architecture of Iran are formed, and this makes it important to analyze these processes. The object of this paper is to present a framework for considering change of semiotics system caused by factors affecting the urban identity and comparing these systems in the old and new textures of the city by layered attitude toward the city as a multimedia text. The research is qualitative and the method of research is descriptive-analytic analytic and Semiotics has been used as a tool and method for considering representations and analyzing the identity of the city. Studies in the old context relied heavily on documents and in the new context is field and the samples were studied in hot and dry areas of Iran.The results show that based on the study of representations in the symbolic system in the textual layers of the city form, the duality of meaning and identity of the old and new textures of a city over time indicate several main factors of change within the textual layers of the form of city, the rupture and duality in the human layer and change in the system of codes that affect the structure of the city form, which is manifested in the elimination, replacement or change of signs in the natural, social and artificial layers.

 today, the importance of the square that have once been a place of interaction for city dwellers, has diminished. the purpose of this study was to identify the effective parameters on improving the quality of space and preserving the historical identity of the square and organizing the square by providing scientific and practiced solutions to enhance the quality of space and preserve its historical identity. This research is of descriptive-analytical type and the statistical population in the present study are people  in square .random  sampling from people of different ages and insights , after starting with the least number , continued until we reached the theoretical saturation of research.the data collection tools are field and library.the analysis was in the form of an open and closed-ended questionnaire that the validity of the questionnaire was assessed as face validity (experts opinion) . and  whit using the swot technique and spss software were analyzed. among the various items to memorize the square , the name of Gharamalek square with 59.3 % is reminiscent of the historical  and valuable space and with naming this space a living historical place is embodied in people's minds.the sum of factors and applications such as the comprehensive mosque , the historical bath , the silk road and etc have been instrumental in establishing the identity of the square.the silk road that used to cross this area in the past and is not known today , ad a negative effect on people's mental image.
