Thus, to understand the roots of a problem and overcome that problem understanding the complexity of the environment, and a complex and dynamic administrative system are essential. Therefore, with increase in the levels of complexity and diversity of social systems, application of complex theories and adaptive systems to cope with them is vital for administrators. However, the role of the capital and its administrative system is very important. Especially in developing countries, due to excessive centralization in political, economic, cultural, and administrative structures, and interrelations among them as well as providing direct service to public by local government. Thus the aim of this study is emphasis on diversification and complication of local government system proportional to the complexity of its environment as a way to solve the problems associated with the capital’s social system. In this line, emphasis on the need to design systems that are compatible in terms of complexity is essential for administrative systems. In turn, for better success in today's changing environment and administration by city administrators, it is recommended that systematic thinking should be taught through workshops, complex adaptive systems theory, complexity theory and the law of requisite variety CP - IRAN IN - LG - eng PB - Geographical-Researches PG - 138 PT - Original Research YR - 2017
