Nowadays the diversity of viewpoints about spatial structure of the cities, given the irregular growth of them and complexity of physical structure and social behaviors and related issues such as informal settlement, needs to use the new methods and techniques to facilitate the decision-making process. The space syntax is one of these new techniques to study the spatial structure of the cities. In the urban system especially the suburban areas, given how mass and space are placed, developing urban spaces has influenced the citizen behaviors during the time. In these textures low permeability and texture isolation, have highlighted a kind of isolation and separation from the city context (spatial isolation) leading to the decrease of place belonging feelings. This study using space syntax method tries to survey the relation between spatial arrangement and citizen behaviors in the urban spaces during four periods of geneses and formation of Nodeh district using integration factor and the role of integration value. The study results show that by developing modern streets the standard deviation of the integration value has decreased and therefore the spatial structure and solidarity of Nodeh district has reduced.
