Localization of Optimal Spatial Management Indi- cators of Metropolises with Sustainable Development Approach, Case Study: Tehran Metropolis

The metropolis of Tehran, as the capital of Iran, faces nu - merous physical, spatial and functional challenges. The purpose of this study is to provide criteria and indicators of the optimal model of spatial management for the metropo- lis of Tehran with a sustainable development approach. The research method, qualitative method and the main tool of data collection and analysis, Delphi Technique have been selected. The statistical population of the study is the me- tropolis of Tehran and the statistical analysis unit including officials, executives and managers of relevant national, pro- vincial and local executive bodies; Academic experts and experts in the subject area of this research and consulting engineering companies. The sample population was 30 ex- perts in the relevant fields. In addition to Delphi stages anal- ysis, a set of qualitative and quantitative analysis methods including Content Analysis, rational and logical reasoning and one-sample T-test have been used. The results show that the sustainable development of Tehran metropolis depends on the desired model of spatial management of the metropo- lis. The components (criteria) of such a model are: integrity, participation, flexibility, responsibility, accountability, stra- tegic, forward-looking and sustainable. Also, the favorable situation of spatial management of Tehran metropolis should monitor the realization of various dimensions of sustainable urban development and meet the different environmental, socio-cultural, institutional, economic and physical-spatial .needs of the metropolitan area
