Today, urban vitality, as a comprehensive paradigm with a wide range of content has received special attention. Therefore, this as an analytical research, with an integrated view (due to the nature of geography), seeks to investigate different approaches in the field of urban vitality, while examining the approaches of vitality, to provide a conceptual model derived from it for the purposes of framing the future research based on this concept. In the same vein, the present article, which has been provided in terms of its fundamental purpose and its data by using the library and documentary research, has sought to answer the following questions: What are the factors affecting urban vitality in the framework of systems of evaluation of approaches (psychology, environmental, social, functional and sustainability)? And also: What is the relationship between the main dimensions and elements of urban vitality? The findings of the research show that urban vitality is not an intrinsic and an environment-based characteristic, and as a socio-spatial event, it is the result of a long-term trend of user satisfaction in urban spaces, that is formed in the interaction between the city and the citizen among several functional layers in a time scale. Therefore, urban vitality, in spite of multiple approaches with different interpretations, shows diverse spatial sequences with a comprehensive urban viability perspective and interpretations of the spatial attributes that demands a set of existing indicators with a transparent spatial approach.
