Urban green spaces are essential for the well-being of the population. However, due to various factors, the distribution of green spaces among city neighborhoods in quantitative and qualitative dimensions is often skewed. Hence, urban planners require effective tools to evaluate and analyze green spaces among the neighborhoods. The most common indicator used in green space assessment is the total area of green space to the total population, however, this index does not provide information on how green space is distributed in the city or region, as well as its ecosystem and ecological effects, which requires a more comprehensive study using new metrics. The aim of this study is to provide tools for a more comprehensive assessment to evaluate and plan better the location and quality of green spaces in the metropolis of Mashhad. For this a set of indicators for green spaces in a multidimensional framework was applied. The indicators considered (i) the total area of green spaces in relation to population and urban context, (ii) the quality of green spaces based on its size, density, the average Euclidean distance, and (iii) the accessibility of green spaces based on its shape, aggregation index, share of population supplied by GS, using the Geographic information system, Fragstats software. The proposed indicators were tested in seventeen municipalities of Mashhad. The results show that districts 17, 6 and 7 have the best and districts 15 and 16 which are among the least privileged areas of the city, have the worst situation of spatial distribution of green space in Mashhad.

Introduction
Access to open spaces in urban areas is one of the important principles of passive defense. This is because of the large number of post-crisis casualties, mostly due to the inability to access outdoor space as well as the ability to escape the danger zone.
Data and Method
The aim of this study is to investigate and accessibility of open spaces of urban areas in case of emergency from the perspective of passive defense of region 1 of Tabriz. For this purpose, in this research, related software such as 10 ARC GIS, Auto cad and Excel software have been used to zoning different spaces based on vulnerability and also to analyze information.
Results and Discussion
The results and findings of the study indicate that 67.3% of Tabriz Region 1 is in a good position in terms of access to open space in terms of passive defense against crises. But to increase the quality and quantity of these conditions to the desired level, improve the functional condition of open spaces (green and enclosed space) and increase the width of streets and alleys leading to the open space.
Conclusion
so that quick and easy access to the organ is possible. Provides things like volcanism, etc. in times of crisis, is of particular importance.
