THE STATE OF THE GREEN INFRASTRUCTURE AND THE ASSESSMENT OF ITS BIODIVERSITY IN THE PARK AREAS OF THE URBAN ECOSYSTEM OF ASTANA

Abstract

The intensive urbanization of Astana city affects the quality of the green infrastructure of the city, its species composition, the vital state of the flora, which ultimately affect urban ecosystems and the quality of life of citizens. The study of the state of the flora of park areas contributes to the conservation of biodiversity, improvement of the ecology of the city, improvement of recreational resources to maintain the well-being of the urban environment.
This article examines the current state and biodiversity of the flora of the park areas of Astana in the context of urban ecosystem services. Based on historical, statistical, cartographic, field, and floral studies in urban ecosystems of park zones in Astana, a comparative analysis of biodiversity and the living condition of trees in Central Park, Zheruyk Park, and Zhetysu Park was carried out. A detailed retrospective analysis of the formation of the green infrastructure of Astana in the period from the end of the XIX century to 2024 was carried out, within the framework of which statistical data, cartographic and floral materials of the studied territory were studied. Based on satellite data and field research, we have compiled maps and tables characterizing the biodiversity and the state of woody vegetation of the above-mentioned park areas. Field studies were conducted using the methods of assessing the vital condition of trees by V.A. Alekseev and S.A. Kabanov, and also the density of the stand in the test sites was determined according to the method of R.V. Azarchik. As a result of the conducted research, some problems of landscaping and conservation of park areas in Astana have been identified and recommendations for the conservation of woody vegetation of park areas have been proposed.
