The Features of the Environmental Transformation in the Modern City (case study of Krasnoyarsk)

Urban planning concepts for mass housing construction were tested in the cities of Russia before the XXI century, the legislative framework changed, the centralized architectural activity lost its force. The diversification of the economy, the development of socio-cultural processes radically changed the approach to the formation of the city environment. The fulfillment of the requirements for the intensification and rationality of the use of territories without a comprehensive study of the city morphology changing often leads to the environment deformations. The purpose of the study is to identify the tendencies of the city morphology development under the influence of changes in ideas about the environmental quality. The city environment is understood as the unity of the natural and anthropogenic landscape, as well as the effective force - the citizens. In the study, the tasks were: to identify the most sustainable elements of the natural framework, constructed areas in a historical sequence; to determine the morphological periods of the Krasnoyarsk development, morphotops of the residential territories; to investigate the structure of the city fringe belts; to formulate the tendencies of the development of lower tier pf the residential housing and public spaces as the most susceptible to change under the influence of socio-cultural processes; to formulate the tendencies of the morphological development of Krasnoyarsk. To determine the boundaries of morphotops, calculate indicators CIS-tools with georeferenced data were used. To analyze the functional density of saturation of morphotopes with objects of small and medium-size business geoanalytical visualization of “functional flows” was performed. To assess pedestrian accessibility and visual connectivity, a spatial syntax method was used in the work. The main results of the calculated indicators were produced be the method of exploratory data analysis/ As a result of the study, the socio-cultural processes influencing the development of the morphology of the city were established; morphological period of the city development, morphotops of residential arears have been determined, changes have been made to the typology of public spaces, the concept of fringe belts has been confirmed, a new type of fixation line has been established, the pattern of development of lower tier of residential housing have been investigated. These results characterize he features of the transformation of the city environment and can be used for the purpose of architectural and urban design.
