Introduction
In order to create favorable living conditions, urban Changes is a permanent and continuous process and has long-term effects on the development of cities. Environmental change as a dynamic process and a key component in the experience of the city, seeks to create a solution to solve problems in various place and human dimensions. Although transformations and changes can be effective in solving urban and human problems, they can have unintended consequences if they do not occur in accordance with the perceptual and spatial conditions of individuals. In order to adapt change to the perceptual and spatial conditions of individuals, and thus improve the relationship between human-human and human-place, it is necessary to understand the different types of change in the city and different transformation processes.
Cities are constantly undergoing transformations and changes, and finally the transition to another stage or structure, based on different needs and demands, in order to improve and establish the desired situation for human beings and with the aim of creating a new content and meaning. But what is not clear in the concepts of transition, transformation, and change are the semantics, lexicography, the position and relationship between them, the types, dimensions, and purposes of each in urban life.
An initial review of the research related to the mentioned concepts shows that not only the definition and lexicography of these concepts have not been clear and their position in the urban issues has not been determined, but also in most of these researches, the mentioned concepts have been used instead of each other.
In the present study, by understanding the relationships between the mentioned concepts, we try to present a more specific process in making various changes, in order to have a more effective impact on humans. Therefore, retrieving and introducing the role of each of the components of urban transition, transformation, change, and their impact and relationship to each other can be considered as the main goal of the research.
Materials and Methods
In order to study the concept, to understand the goals and different types of transition, transformation and changes in the urban environment, the documentary method was used to collect the required data and basics. Qualitative content analysis method has been used to find out the relationship between these concepts and their interaction.
In addition, the meta-synthesis method has been used to analyze the qualitative findings related to urban transition, transformation and change and their relationship. It is a combination of meta-study methods and a coherent approach to data analysis that explores new and fundamental subjects and metaphors.
Therefore, based on reviewing relevant texts and valid documents in the field of urban transformation, transition and change, this study analyzes the opinions of experts and expresses how the mentioned concepts are related and makes them clearer.
Results and Discsussion
In general, with the studies done and the meta-synthesis of existing theories, there is no quite clear definition of the terms "transformation" and "transition". What is clear in the concept of transition is that in any situation and type that occurs (evolutionary, purposeful, gradual and transformed), there is a latent deformation or change of state that can lead to the creation of a new structure or evolution and movement in the existing structure with progress in various dimensions and going through the stages of birth, growth, maturity and death.
Transition as a complex, dynamic and uncertain system is accompanied by transformation processes in which existing structures, institutions, behaviors, cultures and method are decomposed and lead to the evolution and improvement of the existing structure or a new structure is created. Transformation processes are discrete and continuous and lead to changes in various physical, social, economic, political, etc. dimensions of form, function or situation to another state.
It should be noted that internal stimulus of change (power, political leadership, learning from natural disasters, responsibility, increased public and private intermediaries, social participation and innovation) and external stimulus of change (external political, economic, physical and social conditions, energy crisis, external biological conditions, and climate change) all influence the formation of transitions.
Urban changes are artificial or natural. Artificial changes are intentional or unintentional. intentional change can be categorized in terms of duration (long-term, medium-term, and short-term), speed (fast, medium, and slow), and type (physical, social, economic, political, and environmental). Natural changes are sudden (such as fire, etc.) and gradual (such as soil erosion, etc.). It is important to note that each type of changes can affect each other.
Conclusions
The concept of transition can be considered as a process consisting of complex and dynamic transformation processes that take place nonlinearly, purposefully or evolutionarily over a certain period of time (25-50 years) whose main feature is irreversibility. Based on this, it can be stated that transfer is a kind of transformation that targets all the various economic, political, cultural, social, physical and environmental dimensions of a system simultaneously, mainly under the influence of external factors and stimulus. This process occurs over a period of time and leads to shock in the process of transformation and jump from one state to another.
Transformation is considered as a necessary process for the city, consisting of changes in various dimensions, which is a conscious or unconscious and continuous process that is mainly driven by internal stimulus and forces and can be Returnable or reversible.
In addition to the mentioned concepts, to provide a general redefinition of the concept of change, it can be said that changes in the urban environment are dynamic, periodic processes and a major component of the city experience whose ultimate goal is to solve urban problems in various dimensions, although this goal may not always be set.
Finally, it can be said that the transition causes various urban transformations in various physical, economic, social, political and environmental dimensions, which itself has led to the emergence of visible and hidden urban changes in the mentioned dimensions. Therefore, changes in the urban environment are a dynamic and integral part of urban transition and transformation.
