Analysis of the Relationship between Construction Concentration and Sustainability Levels in Babolsar city

Today, achieving sustainable development and proper and sustainable construction density in the cities to improve the quality of life and improve the urban environment is considered as a necessity of urban development. The increasing urban population growth, resource constraints and the rational efficiency of existing facilities increase the importance of paying attention to the density of urban areas. Since demographic and construction densification is one of the most important means of urban planning in order to balance and create order in a complex urban system. Accordingly, the need for a deep and deep view of the topic of urban density and its effects on other urban phenomena is felt more than ever.The present research is analytical-descriptive. In order to collect information for the study of construction density, statistical blocks of 2011 were used. 384 questionnaires were also used to assess the sustainability of urban neighborhoods. In this study, various statistical methods including Kruskal Wallis and binomial test were used. The results of the research showed that there is a significant difference between the groups of construction density and the level of neighborhood stability in the cities of Babolsar is not equal in terms of density. In fact, it can be stated that there is a significant difference between neighborhoods with different construction densities in terms of physical, environmental and economic sustainability. Neighborhoods with average building density in terms of physical, environmental and economic sustainability are better than low-density (construction) and high-density (construction) neighboroods. However, in terms of socio-cultural sustainability between neighborhoods with different construction densities, there is no significant difference and the situation of this aspect of sustainability is not related to the density of construction in the neighborhoods. In general, Babolsar is not in a good position in terms of sustainability.
