This research aimed to investigate the sustainability status of the historical-cultural area 8 in Tabriz, a metropolitan city. The study was descriptive-analytical in nature. The population consisted of residents from various neighborhoods within the eight districts of Tabriz, and using Cochran's formula and a simple random classification method, 375 individuals over 15 years of age were selected as the sample size. The questionnaire's validity was confirmed by experts, and its reliability was obtained using Cronbach's alpha formula, with values ranging from 0.876 to 0.881 for different parts of the questionnaire. Fuzzy TOPSIS was employed to evaluate the variables, the sustainability barometer model was used for sustainability evaluation, and statistical tests were used for data inference and testing. GIS software was utilized for mapping purposes. The findings indicated that the Bazaar neighborhood was the most stable neighborhood, while the Tapli Bagh-Damaskiah neighborhood was the least stable neighborhood within the eight districts of Tabriz metropolis. In terms of sustainability across the six neighborhoods in the eight districts of Tabriz, economic sustainability had the highest positive impact, while environmental sustainability had the lowest positive impact. The district's status regarding human well-being and ecosystem well-being was 0.585 and 0.542, respectively. Single-sample T-tests revealed that, based on the sustainability barometer results, economic, social, physical, and environmental dimensions were prioritized in that order. Tukey's and Shafe's tests further confirmed the existence of a sustainability gap between different dimensions of sustainability. In order to enhance the overall sustainability status, it is recommended that city managers focus on improving environmental indicators within the city's core neighborhoods.

Historical spaces of cities as symbols of identity to city that for some reasons such as the passage of time, lack of compliance with the principles of modern urban planning, communication routes, non-engineering access, etc, have lost their effectiveness, despite the importance of historical spaces These spaces have a low enjoyment coefficient in terms of access to urban infrastructure, and solving this problem depends on accurate identification of components, understanding the relationships between components and finally identifying key components.

The main goal of the current research is to identify the key components in the field of improving justice in access to urban infrastructure in the historic-cultural municipality of region of Tabriz.

The research is applied, and its descriptive-analytical approach is based on the prospective approach. Research data has been obtained using Delphi group comments. The number of components of the research includes 21 components in service, urban, managerial, and historical dimensions. Also, the members of the Delphi group included 19 people.

Geography area of research:

 The scope of the present study is the historical-cultural municipality basin of the eight metropolitan areas of Tabriz, where more than 80% of the historical monuments of Tabriz are located in this region.

The findings showed that out of a total of 21 components affecting the improvement of justice in access to urban infrastructure in historical contexts, 11 components are the key components. The most important key components are the improvement of visual quality, improvement of transportation, and retrofitting old buildings, etc. Also, the results of the Electra test in the field of prioritizing the seven neighborhoods located in the historical-cultural municipality of the 8th region of Tabriz showed that, respectively, the neighborhoods of Shahnaz, Bazzar, Mansour, Maghsoodieh, Daneshsara, Karabagh-Balahamam, and Taplibagh-Damaskia are in the first to seventh priorities.

The results of the research showed that the three components of improving the quality of public transportation in historical contexts, the per capita improvement of urban green spaces, and the preservation of historical symbols as three key Factors in the field of improving justice in access to urban infrastructures in historical contexts. From this point of view, it can be said that Shahnaz, Bazzar, and Maghsoodieh neighborhoods have grades one to three, respectively, in terms of access to urban infrastructure. Finally, practical proposals were presented in the field of promoting justice in access to urban infrastructures of historical contexts.

The appropriate urban governance approach is one of the newest and at the same time most reliable approaches to urban management. This new approach in urban historical contexts has a multidimensional function in terms of improving the conditions of historical contexts because it will lead to the preservation of urban identity, improving the appearance and urban landscape, and ultimately increasing citizen satisfaction. The cultural-historical municipality of Tabriz Region 8 is one of the most historic urban areas among all cities in Iran that has not been studied from the perspective of optimal urban governance. The historical region of Tabriz is 8. The nature of the research is applied research that has been done descriptively-analytically and inferentially. The statistical population of the study consists of residents of District 8 and academic experts. The sample size was 377 people who were selected by simple random sampling. The reliability of the questionnaire was 0.901. The research findings were analyzed using Pearson, regression, and ANOVA statistical tests as well as neighborhood prioritization using the Vikor method. Findings showed that the 15 variables were able to explain 89.6% of the variance changes related to optimal urban governance. Also, the results of the ANOVA test show that there is a significant difference between the seven neighborhoods in terms of desirable governance indicators. Finally, the results of the Vikor test showed that Bazaar, Shahnaz, Mansour, Daneshsara, Maghsoudiyeh, Tepli Bagh-Damascus, and Qarabagh-Balahamam neighborhoods are in the first to seventh ranks, respectively. Finally, according to the research findings, practical suggestions were presented.

Despite the importance of historical textures, all kinds of financial, managerial, and physical problems have prevented the development of these textures. Considering the importance of this position, the main goal of this research is to identify the challenges of managing, and creating valuable historical urban contexts in the metropolis of the Tabriz. The nature of this research is applied and descriptive, and analytical. The statistical population of this research included households living in District 8 of the Tabriz Municipality and 20 urban experts. Using Cronbach's alpha methods and simple random methods at the household level, 367 people were selected as the sample size. The MicMac software was used to analyze the research findings and the statistical test of linear regression in a step-by-step method. The results of the research showed that the lack of urban infrastructure including green spaces, the location of historical contexts within the city and traffic problems, the challenges of crisis management within the historical context, and the high density of construction within these contexts and The difficulty of vehicle traffic with the values of 1362, 801, 769 and 865 are the key components (challenges) in the field of managing the development of the valuable fabric of the Tabriz city in the 8th urban area. Also, the findings of the research using a step-by-step linear regression test showed that the key components of the management of the valuable tissue include adopting an integrated approach to the management and development of the valuable urban tissue, coordinating the actions of other executive bodies through a comprehensive approach, the ability of managers' knowledge. A city related to local management and relying on local components of valuable historical context management. Finally, the most critical solution to solving the challenge of managing the development of historical structures is to pay attention to all the managerial, financial, social, and physical-infrastructural aspects simultaneously.
