Monitoring the transformation of architectural and urban planning and panoramic visual acceptability of the historical part of Irkutsk

The present work discusses dynamics in the architectural and urban planning of the urban environment for identifying and preserving the most significant visually acceptable architectural ensembles and panoramic views of Irkutsk. Visual landscape and cartographic analysis by specific indicators were used as the main research methods. The article reflects the predevelopment analysis devoted to collecting initial information for the student's project entitled "Reconstruction of the quarter in the historical part of the city". The work was performed by fourth-year students studying "Urban planning" in two stages at different urban planning levels. Stage 1 included the analysis of visually acceptable views and panoramas of the urban environment at the city level. In stage 2, the existing development at the quarter level was carried out. A retrospective analysis of the urban environment is represented in the form of graphic models reflecting the current state of visual acceptance and the lost fragments of architectural ensembles in the centre of Irkutsk. The conducted visual landscape analysis of historical and contemporary panoramas of the city revealed dissonances and conflicts in the visual acceptance of the main urban ensembles. The results of the rhythmometric analysis obtained for the development front in the quarter are represented as a model limiting the building height within the quarter. Such a model was developed to eliminate conflicts during reconstruction and establish urban patterns, including valuable urban planning heritage. The obtained results are relevant for studying the urban development of territories with historical and cultural potential and can be used in urban planning regulation of historical cities and areas with historical development.
