Undoubtedly, the discussion of sustainability and sustainable development, regardless of cities and urbanization, will be meaningless. Cities are considered as the main cause of instability in the world because the characteristic of our age is urbanization, increasing the population of cities and consequently the development of small and large cities. During the period 1990 to 2030, the population of urban areas will grow to about 3.3 billion people, of which 90% will be in urban areas of developed countries. Attracts urban planners to the concept of sustainable urban development, the reality of rapid urbanization growth in the world today and its continuation in the future on the one hand and the amazing growth of metropolises especially in southern countries and its harmful consequences for the inhabitants of these areas. is. The concept of sustainable development has been used in various ways in various forms, but the most central idea is the World Commission on Development and Environment, which was stated in 1987, according to this definition, is sustainable development. To be able to meet the needs of the present generation without sacrificing the ability of future generations to estimate their needs. In Iran, the process of rapid development without planning and considerations of urban centers; By sharing resources, it destroys the marginal lands, gardens, forests, creating incompatible uses, and finally, water, air, soil, etc. pollution on a large scale on the face of urban environments. It can be seen that it has upset the balance of natural ecosystems. The metropolis of Isfahan has been selected as the scope of the present study; Based on statistics and information available in various fields affecting urban sustainability, it has a considerable distance from global standards. On the one hand, the increase in population (more than 8 times) during the years 1335-1395 during recent decades, along with the natural increase in population has caused this city with numerous social, physical, environmental and housing problems. , Transportation, etc., on the other hand, inappropriate use and over-capacity of natural resources, change and destruction of natural ecosystems, land use change and the creation of unequal urban spaces in the city, environmental pollution Inadequate wastewater disposal, lack of interaction between different sub-sectors of transportation, low level of services, high population density and also insecurity, the existence of which can be considered as an important factor in urban development, this city with It faces serious challenges related to sustainable urban development.
This research is applied in terms of the purpose of the research and in terms of the nature of the methodology is based on descriptive-analytical research and based on library studies and field studies. The method of data collection is a questionnaire that 375 people were randomly selected by purposive sampling method. In order to achieve the research objectives, 16 indicators include (third place, accessibility, invitability, dynamism and vitality, comfort and security, flexibility, performance, form, meaning and content, social sustainability, social security, Social interaction, social justice, social participation, social belonging and social identity) were extracted. One-sample t-test, Pearson correlation, and Friedman test were used to discover the pattern trend to classify stability indices and the role of third places on them. The geographical area of this study includes all 15 regions. Is a city of Isfahan, which was selected to represent the entire city of District 8 in the north of Isfahan, District 9 in the west, District 3 in the center and historical context, District 4 in the east and District 6 in the south of Isfahan.
Findings and Discussion:
Multiple sample t-test is used to determine the status of sustainability indicators. Multiple regression analysis is used to study the simultaneous effect of the eight components of the independent variable (third places) on the dependent variable (social stability). Is. For this purpose, first the social stability variable as a dependent variable and the eight components of third urban places (accessibility and permeability, inviting, dynamism and vitality, comfort and security, flexibility and functionality, function and structure, form and meaning And content) are entered as independent variables and studied by stepwise method. In order to evaluate the status of the dynamics and vitality component of urban third places, one-sample t-test was used. This test is one of the simplest types of t-tests that is used to determine whether the average observed in a random sample is equal to the assumed population average or not. In order to investigate the relationship between the quality variables of the third urban place (form, function and meaning and content) and the identification of urban spaces in Isfahan, Pearson correlation coefficient test was used to compare the situation of social stability in different urban areas of Isfahan. One-way analysis of variance was used and finally, in order to investigate the spatial correlation between effects (selected indicators) through the Weights Manager box, a set of tools available in Geoda software, weight and coefficient in the pattern process were obtained.
Status of 16 indicators of sustainability of third places; Selected areas in Isfahan are in a relatively good condition. Also, the distribution of macro-indices in the third places as output values through the Moran I global index for this study were clustered in each index, respectively, and had a positive spatial autocorrelation (centralized pattern) so that Among different urban areas, the highest rate of social stability in the third places is related to urban areas 3 and 4 with averages of 89.09 and 87.61, respectively, and the lowest level of social stability is related to urban areas 6 and 8 with average, respectively. The dates were 83/20 and 83/42.
