On the Analysis of Urban Hierarchy and Balancing the Spatial Distribution of Urban Centers Population in Guilan Province

Urban hierarchy in terms of quantity is the best form of organizing space. Because it makes the distribution of activities and services at the community level, balancing classification, performance and appearance of different ways of life in the various geographical areas .Population distribution system is not balanced in the province and do not get a proper image form of accommodation and population settlement and cities .It was determined by studying the urban hierarchy of Gilan province during the years 1355 to 1395 .It was determined by studying the urban hierarchy Gilan during the years 1355 to 1395 the city of Rasht as the capital of Gilan and the metropolis area with a 42.41 percent of the urban population in 1395 in the "First City" demonstrated their dominant role and now all factors: geographical, social, economic, political, cultural and ...is in the interest of the city and to the detriment of small living centers. Meanwhile, concentration of the population led social and cultural difficulties such as housing problems, expensive land, rent, traffic congestion, failures in service and finally, a wide range of environmental contamination. This city in terms of having appropriate areas of political, economic and cultural, various migrants from surrounding areas has attracted and has been away urban hierarchy of Rank – Size law; So that in 1355 the city of Rasht was 3.41 equal the second largest city (Anzali).In 1390 the population of city of Rasht is 5.48 equal the second population (Anzali).To determine the population dynamics and rank cities in recent years, and its effects on the unbalanced development of urban centers, centralization and domination of one city in the provincial urban it is necessary to take measures in order to spatial organization of urban centers and a balanced distribution of geographical Society according to the possibilities and the limitations and comparative advantages of each region and with respect to land use planning policies and modify spatial development of urban centers. The most important approaches of this research is centralization Of city and Rasht area and attention to small and medium cities Province.
