The Explanation of the Peri-Urban Conceptand the Factors Affecting Its Creation and Development

Peri-Urbanization (sometimes referred to as the urban fringe) may be a dominant urban form and spatial planning challenges of the 21st century. In industrialized or post-industrial countries, Peri-Urban is the domain of economic, social and spatial change, while in newly industrialized and most developing countries, it is often a chaotic urban region that causes disharmony and incoherent development. In both cases, in addition to some intercity and suburban outskirts, Peri-Urban can be considered a transitional zone and play a greater role as a functional territory. Although a clear and simple definition cannot be found for these areas, there are common features wherever such areas are found. Many global challenges arise from the ways that cities grow and change, especially the emerging mega-cities in developing countries such as Iran, where massive social and environmental problems can be found in their peri-urban hinterlands.

Because these areas have relatively low population density by urban standards, scattered settlements, high dependence on transport for commuting, fragmented communities and lack of spatial governance, Explaining the concept of Peri-urbanization and the factors affecting the creation and development of these areas the goals of this research.

In this research, with an analytical-descriptive approach, a general overview of the phenomenon of urbanization in the European and global concept was conducted. The content analysis method also examines the content of the internal studies conducted by concerning Peri-urbanization. Finally, by introducing a five-dimensional framework that has been adapted from a comprehensive and integrated global study on peri-urbanization to the general study of the theoretical foundations or literature of the subject was examined. To explain a general narrative of how the Peri-Urbanization settlement took place in the present era, considering all its dimensions.

The results of this study show how political, socio-economic and physical driving forces are influential in these areas and as a result of research, a framework for distinguishing the degrees of change in the Peri-Urbanization system from the perspective of different types of links, scales; Spatial development, transformation, resilience and governance will be outlined.
