Investigating Effective Spatial Structures in Neighborhood Sustainability Based on Urban Planning Science (Case Study: Gomishan City)

 This study aimed to investigate the factors affecting the sustainability of Gomishan urban areas. Understanding the situation of urban areas plays an important role in achieving sustainable urban development. The neighborhood is one of the important elements of the urban body, and the balance of social life in cities depends on maintaining the neighborhood. Nearly three decades after the introduction of sustainable development, the focus on social sustainability in terms of economic and environmental dimensions has been very low; but in recent years, the literature related to this dimension of sustainable development has expanded. Studies show that they are the best scale for assessing and measuring the social sustainability of urban neighborhoods, but the important point is the multiplicity and diversity of indicators at different levels and scales with intertwined causal relationships. Thus, today, the creative development approach, which nurtures and nurtures local talents in innovative ways, has attracted much attention at various levels of decision-making.

 The statistical population of the study included people over 18 years old living in Gomishan in 1400, from which 210 people were selected by available sampling. The sample size was based on the Morgan sampling method, which was 20 questionnaires for each urban area. To access them, a sample has been assigned to them from the systematically classified method according to the neighborhoods and the population of the neighborhoods. To analyze the data obtained from field operations from a one-sample t-test to measure the state of stability, from analysis of variance to compare urban textures in the form of SPSS software, and from multi-criteria decision models (Electr, Topics, Copeland, and Vicor) have been used to rank urban areas.

 The results of the one-sample t-test showed that the stability of the neighborhood is undesirable. The one-way analysis of variance indicates there is a big difference between Gomishan urban areas in terms of the level of stability so that Gomishan urban areas in The two categories were unstable and relatively stable. Finally, multi-criteria decision-making models showed that the share of economic sustainability and physical sustainability (infrastructure development and facilities) as sustainable urban dimensions is higher than the other two indicators (social and environmental sustainability) as well as vitality components and Participation is in a bad situation and this situation is different among districts of Gomishan city.

 The results showed that most areas of Gomishan city are in an unstable situation in terms of economic dimensions. The results showed that most areas of Gomishan city are unsustainable in terms of the environment. It has suggested that green spaces for sports and leisure expanded and the sewage network of neighborhoods. It is one of the main threats, to be completed and maintained. Considering that the areas of Gomishan city are also in an unstable condition in terms of physical dimension, it is recommended: to avoid creating dry and lifeless environments, and rough and rugged buildings inside the neighborhood, and to create mixed uses to increase access and reduce travel costs. Urban neighborhoods' continuation of the current trend is the main challenge in achieving sustainable urban development. The results show that most variables and dimensions of research are in a state of stability, among the variables, dynamics and adaptability, access and services, identity, security and health, vitality, spatial affiliation, social capital, participation, employment, and contaminants are in moderate to high stability. Among the dimensions of research, the social aspects have a relatively good situation, and the institutional and environmental dimensions are in a state of instability, and in general, the stability of Gomishan neighborhoods and urban contexts is at a moderate level.
