Revitalization of regular landscapes of the Arboretum exposition zone of the State Biotechnology University

Abstract

Purpose. To substantiate the concept of revitalization of regular landscapes of the exposition zone of the dendrological park of the State Biotechnological University. Methods. Field, laboratory, geoinformation, computer modeling (QGIS 3.28.3-Firenze 2022-08-31, Realtime Landscaping Architect 2023.02, Trial Free Version and Sketchup). Results. The historical context of the creation of the arboretum, the agro-ecological status of the elements of soil fertility, its trace element status, the ecological-ameliorative and ecological-toxic state were studied. The selection of introducers was carried out for the 5A climatic zone of winter hardiness (USDA-zone). Geoinformation modeling of the studied space was carried out, relief isolines were created. A revitalization project of regular landscape compositions of the exposition zone of the dendrological park has been developed. Taking into account the soil and climatic conditions in the formation of plant compositions requires the use of introducers that do not require a high level of available nitrogen compounds, but respond well to an increased content of mobile phosphorus and potassium, do not lose decorativeness when grown without irrigation or with the use of minimal soil protective irrigation, with high resistance against diseases and pests and will serve to increase the biological diversity of the urban landscapes of Kharkiv and other cities of Ukraine located in the 5th winter hardiness zone (USDA zone). Conclusions. It is proposed to preserve the approach proposed by the founders of the dendrological park, that is, to restore the decorativeness and expressiveness of plant compositions, but in the context of making nature-oriented decisions, to enrich this approach with an ecological feature.
