An analysis of the spatial organization of urban levels during the years 0931-39

Lack of attention to the urban system and the way it is distributed and its spatial pattern in the land on the one hand and the rapid growth of urbanization on the other hand will lead to disruption and incoherence in the spatial structure. Under such circumstances, many development policies at the national and regional levels have lost their effectiveness And it will not bring the expected results. The purpose of this article is to use a mathematical model to justify the current situation of how to establish the population of urban centers in the geographical area of Fars province. In this article, while introducing the entropy model, this model has been used in the cities of Fars province. In this regard, the results of the general population and housing censuses of 1390-95 in Fars province have been used To determine the process of change and developments in the provincial space organization in the last thirty years. The research method in this research is descriptive-analytical with a developmental-applied approach and the required information is collected through the library method. One of the most important results of this study is that the entropy coefficient in the cities of Fars province during the years 1390-95 has been calculated to be 0.63, 0.67 and 0.54, respectively Which represents the disorder of urban population concentration over the past three decades.
