  This paper contains a comparative study of neighbourhood transformation taking place in different administrative parts of Tehran city in Iran. The way of occupation of different areas of the city show it’s certain economic, social and cultural identity and presents different landscapes in city. This paper tried to answer this question that how is population density during 1996, 2006 and 2011 in Tehran. This tried to recognize the spatial pattern for population density using ArcGIS, Geoda and techniques of spatial-statistical analysis especially spatial autocorrelation in better way by spatial-temporal investigation. Spatial autocorrelation measures the correlation of a variable with itself through space. The results show that during the three periods of 1996, 2006 & 2011 pattern of population distribution in Tehran has been clustered and has changed during these three periods. Although the intensity and concentration of High-High and Low-Low clusters is reduced however, the more high-density clusters have been formed in the city. Indifferent (Residual) zones have emerged during these periods in places where the High-High zones have formed, this means that New boundaries will change to form high-high clusters.

  When the damage condition occurs, accidents such as earthquakes and floods become critical crises. Today, these natural crises are among the issues that are the prevalence of urban communities and can endanger the everyday life of various economic, social and environmental dimensions. This research is also aimed at explaining social factors that provide vulnerability conditions. Based on this nature, it is descriptive-analytical in nature and in terms of the purpose of developmental-applied purpose. The community of this region is 6th municipality of Tehran, which has been selected as a sample based on the age and the centrality. The data were collected in two fields of the field and a library with tools such as the Dmitry questionnaire and network analysis, books, articles and various maps, and analyzed using EXCEL, MATLAB, IDRISI and ARC GIS 10.1 software’s. The results indicate that the highest vulnerability of the center, the south, and especially the south-east of the range, are among the problematic tissues with a high life and age, as well as the highest density of buildings, population and household size they also have to. The presence of such factors has a significant effect on the access of residential areas to fire centers, therapies and open spaces during and after natural disasters. Manuscript profile
