چکیده:
Problem statement: The urban view area’s extent is an arena for the classification of Tehran’s governmental and non-governmental squares creating different similarities and dissimilarities in this regard. The analysis of the similarities and dissimilarities can reveal the special and general properties of Tehran’s governmental and non-governmental squares in the urban view area. The comparative study can provide a solution for analyzing the quality and the origins of the differences between Tehran’s governmental and non-governmental squares in the urban view extent even with the existence of similarities. Adopting landscape-based approaches, the other researchers of the urban view areas have not so far made use of a comparative study in regard to Tehran’s squares.Research method: The present study has made use of a qualitative research method andit is applied research in terms of objectives. The present research paper has for the first time investigated Tehran’s governmental and non-governmental squares in the area of urban view based on a comparative research method. The study was, on the one hand, based on the library data and it was, on the other hand, drawn on the field data. Thus, after obtaining the data, the various forms and shapes used in the architectural structures and façades have been compared in terms of the arrangement at one another’s side in longitudinal and transversal proportions and the effects of these shapes have been obtained for the squares’ facades. Research objective: The present study is aimed at analyzing the quality and the origins of the differences and similarities created in the area of urban view. Conclusion: The performed analyses made it clear that the systems forming the square stemmed from the proportions between the dimensions and levels of the openings, positioning of them and façade’s geometry, which was per se influenced by the squares’ positioningand function. Although these systems may have undergone changes in the course of the history of Iranian squares, their contents have lasted till the several recent decades and can be applied as a collection of designing indices by the landscape architects and urban engineers.
