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.

Introduction and objectives of the research: 

Determine the amount of vulnerability of urban tissues with factors affecting the vulnerabilities, one of which must be on before the occurrence of the events and to prepare for the more efficient management of the crisis in the cities. This research will also seek to explain factors affecting the vulnerability. On this basis, except in terms of the nature of descriptive research-analytical and applied to the target type. The Statistical Society of Tehran municipality is the District 6 is based on the dating and centralization as the sample is selected.

Data field and two for a library with tools such as questionnaires, books, articles and DEMATEL diverse map collection, and with the use of EXCEL software, MATLAB, IDRISI and ARC GIS 10, about the analysis of fact.

The results indicates that it is a central, South and parts of; especially the Southeast region due to the high life and dating buildings, population density and high household and communication networks filled the next maze with low permeability, high potential vulnerability.

On this basis the user planning land and zoning as one of the most important tools and yet are critical objectives of urban planning context in the realization of disaster reduction in the risk of a wide view and urban development process.
