The Analysis for Urban Systems Azerbaijan Huge Regional in Years 1957-2007

The present study attempts to investigate the urban hierarchy in Azarbaijan Huge Regional between 1957-2007. The research method is Content and statistical Analysis. The necessity data were collected by documental method. In addition to the analysis and sorting of the data regarding the situation of Azarbaijan cities based on different models such as Entropy index, Ginny Coefficients, Urban Concentration Index, and Rank –Size Model. The goal of research is information for equilibrium measure in urban system of Azarbaijan huge regional. The results of research is show that Azarbaijan urban systems was equilibrium for view of indexes of primate city. But for view models example rank-size, Behforooz, Lorenz curve, Ginny Coefficients, Entropy index to follow for trend of Iran urban system and have many space with normal mann er. Therefore this manner is results of increase number of small cities and addition of population of big cities. Tabriz city with reason centrality of political, administrative, financial,…to settlement with title primate city in Azarbaijan urban system and cities Uromiya and Ardabil with title province center to settlement rank of two and three. Ultimately, Urban Hierarchy in Azarbaijan Huge Regional has very gap compared with Zapf’s Rank-Size model and Behforooz adjustment model. Providing services and strengthening small and middle sized towns coupled with decreasing the growth of mega cities can lead to the optimal distribution of Urban system of cites all over the Huge Regional.
