Abstract
Due to the many complexities, housing planning, especially for vulnerable groups, in a city as large as Tehran, requires a model to simplify the process and speed up calculations, which does not currently exist. With the aim of solving this problem, the present study proposes a model with the following steps: 1) Explaining the objectives 2) Estimating the housing needs of the target community 3) Identifying expandable areas 4) Proposing construction patterns 5) Proposing dispersion patterns 6) Calculations and patterns Financial and 7) suggest operating patterns. The information required to implement the model was collected from two questionnaires and data from the Statistics Center. In this model, three housing models with minimum, optimal and average areas and three types of existing housing construction, 100% infrastructure and freeing up the yard space were used as public urban space. The proposed zoning was adapted to the 22 districts of Tehran Municipality due to compliance with the available data. Sales price and financial calculations were calculated based on the internal rate of return of 20% and contract subsidies, and finally 4 free transfer models, lifelong lease, lease on condition of ownership in the program areas were proposed. The results show that one of the problems in this sector is the lack of appropriate decision-making structure and planning tools that can provide a comprehensive and complete review of the current situation, comprehensive and comprehensive solutions. Therefore, according to the model and using the indicators used, regions 2, 6 and 13 have the lowest and regions 19 and 22 have the highest potential for housing development of low-income and vulnerable groups, and finally, the model has suggested the most housing in regions 22, 4, 19 and 11.

Abstract
It has a complex and multi -dimensional conceptual life and guarantees the performance of the ecosystem from the smallest unit to the surface of the Earth, or in other words from local levels to world levels, and its patterns are quite different from one region to region. In this regard, in the past three decades, in addition to the human impacts, the use of harmful resources and industries, the vulgarity of the ozone, the greenhouse, the greenhouse and the effects of the phenomena, and the phenomena of the city, Various environmental and environmental and remedies have been increased, which has increased melods to zero. For this purpose, in this study, it has been attempted to identify and analyze the key propellers affecting biodiversity by emphasizing the environmental indicators in Tehran's 11 metropolitan area. In this study, with the technique of environmental and Delphi dynamics, 57 primary factors were extracted in eleven different areas and then, using the Delphi method of managers, the matrix of the components of the components was formed. Next, the matrix analysis has been analyzed through the Michemac software. The results of the distribution of variables on the axis of influence and influence of the factors in the Micmac software indicate the system's instability within the scope of the study, and therefore five categories of variables were identified. Finally, due to the high direct and indirect effect of factors, seven key factors were identified as key factors in the field of biodiversity, with emphasis on the environmental indices of the region. Among the preferences under consideration, the variables of public transport status (speed, accuracy, confidence, security, security, convenience, economic affordability) and public access to the green space had the highest impact on the biodiversity in the study area.
