Investigating the Structural and Functional Changes of Urban Neighborhoods in Transition: A Case Study on Southern Zone of District 6 of Tehran

Metropolitan neighborhoods have faced many structural and functional changes in recent decades. They have undergone transformation and transition to a new situation while experiencing major changes. The present research studies the structural and functional changes in the southern part of District 6 of Tehran Municipality, including Iranshahr, Valiasr, University of Tehran and Jamalzadeh as a number of the most important areas of the city. Since these areas have been considered by various organizations and departments in recent decades, data related to their structural and functional changes can be obtained. For this purpose, first, the related scientific sources in the literature have been studied. Then, using field surveys, changes in the functions of the study area have been investigated. Finally, using GIS Software and methods of spatial statistics analysis, the structural and functional changes in the neighborhoods and zoning of the changes have been investigated. The results show that in recent years, parts of residential buildings in the study area have been used for non-residential functions and in the meantime, the University of Tehran neighborhood has experienced the most changes. The findings showed that by passing through the northern part of the region to the south, the amounts of residential uses decreased while the number of administrative, commercial, educational-cultural, service and mixed uses increased. Continuation of this situation caused the formation of a purely official and commercial space without considering the suitable ratios. These all have led to problems in the region and the city of Tehran.
