Adaptive analysis of urban primary phenomena at provincial and regional levels (Case Study: Fars province and Larestan province)

Excessive concentration of population and activity, mainly in the largest cities of developing countries, has caused the spatial equilibrium in the urban network of these countries to be problematic, and has provided the basis for the emergence of the first urban phenomenon. First urban phenomenon on the one hand enhances the attraction of a large part of facilities and services in large cities, and on the other hand, these great cities have faced many problems. The first urban analysis in Iran and most of the world's countries is often limited to large cities, and the high-level analysis processes result in a top-down (centralized) planning fate. In this research, the first urban phenomenon has been tried, in a comparative manner, in addition to high levels, at low levels. The research method is descriptive-analytic and the required information is collected from reliable statistical centers such as Fars Governorate and Statistics Center of Iran. One of the most important results of this research can be a severe rupture in the cities of the province, so that the city of Shiraz in 1395 with 1565572 inhabitants as the dominant city and first in the province of Fars and the city of Marvdasht as the second city With a population of 148858 was on second place. In the regional level due to the natural, economic and geographical conditions that are observed in the Larestan area, the urban network has a better order, so that the city of Lar as the first city with a population of 62045 people and the city of Ghorash With a population of 34469 were on second place.
