the role of government decisions on regional development with the approach spatial planning and sustainable development

power as an institution, governance as structure and spatial organization is considered as an organizational tool in the service of the goals and aspirations of the institutions of power and governance structure. in this framework the spatial organization and geographic environment is a result of social organization (social, economic, political), and its natural and ecological system. human authoritarianism can be the most fundamental strategies and mechanisms of social-biological will be considered in forming this relationship. this needs to be a strategy used by individuals and organizations, and apply to the exercise of power on the part of the space and its contents. the metropolitan centers are concentration of wealth, power, culture, and management and local, national and global forces. therefore, special interest of organizations and the power forces to this phenomenon and the desire to intervene in the organization of functional, spatial can be expected in order to use most of the resources and opportunities. urban society today is filled with many actors who each act according to their interests. today the spatial function distribution can be considered the most important challenges of metropolitan governance. thus, the efficiency and effectiveness of metropolitan governance structure depends on the acceptance of functional diversity in the metropolitan area and its reflection in the form of metropolitan governance. the new project of the government - the nation insisted on the unity and similarity more than difference and diversity. the emergence of multiculturalism as a political force is an indication of the failure of city project and future areas must to develop diversity and differences through democratic cultural pluralism. this paper presents an analytical method and aims to answer these questions: whether it can be constructed such a regional city? what is the basic requirement for this a regional city? it seems principles of social justice (principles that must fuse with the issues of planning and urban governance), such a difference and discrimination, citizenship, community and civic culture are minimum requirements to create a new system of urban civilization.
