Abstract :

Today, in the construction of cities and determining their geographical organs, they think about the balance of the city and the region, the mutual relations between the city and the village, the spatial power and the balance of man and the environment. The creation and growth of fungi in cities with long geographical organs in the regions of the country, where the villages are scattered and dense and there is no organic relationship between the city and the village, will lead to the collapse of these balances. The purpose of this article is to study and influence the central city of Yasuj in the development of Kohgiluyeh and Boyer-Ahmad provinces. According to the studied elements, research objectives and the nature of the subject, the type of research is "applied" by analytical-evaluation method. The information is collected from general population and housing censuses, statistics and library studies. And for data analysis, quantitative methods and models such as: entropy method, rank-size model, spatial coefficient, share change, sphere of influence and elasticity coefficient have been used. Research findings In order to achieve balance in the province, it is necessary to apply strategies to balance and establish facilities and services in other cities of the province. Establishing facilities and services in cities with low populations, in addition to preventing migration to the three cities of Yasuj, Dogonbadan and Dehdasht, will reduce the population gap between Yasuj and other cities. In the study, the results show that the concentration of population, facilities and socio-economic services in the three cities of Yasuj, Gachsaran and Dehdasht is more than other cities in the province and there is a severe imbalance in the cities of the province. Also, in the process of economic structure of Yasuj city in different periods, we are facing the increase of services and industry and the decrease of agricultural sector, so strengthening Yasuj city and cities with less than twenty thousand people in the province, which include 85% of the province cities, can be a good solution for Achieving a balanced spatial structure in the province.
