Abstract

The characteristics of modern urbanisation are leading to the expansion of urban areas at the expense of natural features, primarily green spaces. Green spaces play a fundamental role in shaping the ecological balance of urban systems, ensuring the health of the population and increasing the resilience of urbanized areas to anthropogenic loads. The shortage of green areas in cities, their reduction in area and deterioration of the quality of plantings constitute one of the most acute environmental problems. This article examines indicators, the definition of which is based on the quantitative characteristics of the greening of an urbanized area. The aim of the study is to develop an approach for quantitative assessment of the phytogenic component state based on indicators of greening of the territory and to test the algorithm for certain urbanised areas based on analysis of available statistical data. Among the indicators, general (level of greening of the territory, provision of green spaces for the population) and specific (number or area of structural elements, level of greening of structural elements, recreational load) indexes are highlighted. Calculations of the provision of green spaces have shown significant spatial unevenness of the level of greening of cities. The natural conditions of the city of Bilhorod-Dnistrovskyi are characterized by a shortage of green areas in parks and squares, and sufficient (per inhabitant) greening of residential areas and the general territory of the city. The analysis shows that no district of Odessa meets the minimum requirements of national standards and recommendations of international organizations. The situation of Peresypsky and Kyivsky districts is especially critical, where there is a shortage of green areas per inhabitant. The qualitative state of green areas was additionally assessed. The most balanced in terms of the quality of green areas is the Primorsky district, while the Peresypsky district is distinguished by the worst indicators of both qualitative and quantitative provision. A comparison of the calculated indicators with the standards shows that the actual provision of green areas in Odessa is on average only 15–30% of the recommended values. This indicates systemic ecological instability and a high level of technogenic load on the urban territory.
