Green infrastructure and relationship with urbanization – Importance and necessity of integrated governance

The article uses an interdisciplinary approach to study the links between urbanization and the state of the green infrastructure of the metropolis, which indicates the possibility of providing ecosystem services. This is important for the formation of a better management policy of green urban space for the sustainable development of the metropolis. In order to allow creation of forecast in time, spatial and statistical analysis of the relationship between the criteria of urbanization and ecosystem services were done, which resulted in spatial analysis – showing the distribution of the study area by condition and viability of green plantations depending on the level of urbanization to visualize their complex structure and condition. Indicators of urbanization were researched: 1) urbanization Index (UI); 2) Anthropogenic load index (Jₐₗ); 3) water erosion of the soil; 4) adventization index of grass cover (Iₙₙ); 5) nitrophils in grass tirer; and environmental indicators. Three most important groups of ecosystem services (ES) were identified quantitatively: 1) habitat quality, regulating ES – park area, mortality of trees, canopy density, stand condition index (Is), integral indicator of the impact significance (W), natural value index (Inv); 2) biodiversity conservation – Hₛₜᵣ, Biodiversity Indices; 3) provision of recreational ES – t, R. It was found that urbanization has a direct negative impact on ES, which contributes to the reduction of biodiversity, area, structure and condition of park ecosystems (PE). According to the proposed indices, the studied Kyiv park ecosystems form two large groups – 1) with a significant anthropogenic load and 2) with the best preservation of the forest environment, complex biotic structure. We made recommendations on the policy of management and preservation of green infrastructure in the context of rapid urbanization, especially on park ecosystems of the second group.
