Abstract

Understanding the physical-spatial structure of cities from the perspective of its developments is one of the important influencing factors in the success rate of urban planners and practitioners and can contribute significantly to the improvement of urban environments. In this regard, the present study was written with the aim of investigating the spatial-physical structure changes in Tabriz metropolis. The research method in the present research is mixed (quantitative-qualitative) with practical purpose and analytical-exploratory nature, in order to analyze information were used Heldren's model and Moran and Kernel's technique in ArcGIS software. The findings of the research based on Heldren's model indicate that in the period of 1956-1986, 71% of the physical growth of the city is related to population growth and 29% is related to horizontal growth. In the period of 1986-2006, the population and horizontal growth of the city was almost equal (48 and 52 percent), and in the period of 2006-2021, the extensive population growth caused the vertical growth and the formation of the compact city of Tabriz. Also, Tabriz metropolis is located in a single-core state (city center) and due to the changes that have taken place and the increase of administrative, therapeutic and recreational functions in the eastern regions and industries in the western regions, it has the ability to become a multi-core development model in its spatial structure. In other words, the changes in the spatial structure of the city in recent years have witnessed the decentralization of the city center. The results also indicate that the process of changes in the physical-spatial structure of the city has changed from fast to medium and back to fast, and in the meantime, we are witnessing the wide formation of spatial inequalities and imbalances in different dimensions.
