ESTIMATION OF AIR POLLUTION IN KIEV MEGALOPOLIS USING THE COMPLEX OF BIOINDICATION METHODS
2018
Miroshnyk, N V
In this study a results integrative approach of bioindication correlated with an gradient of anthropogenic pollution on urban ecosystems of Kiev. A large number of cars lead to elevated traffic density and intense traffic jams, with level increase on air pollution levels and obvious negative impacts on human health. Airborne dust matter limit values are frequently exceeded the norm, making negatively affects сondition of trees in city. Trees of Tilia cordata Mill. served as the indicators of air pollution at 36 sites. This are phytosanitary condition of trees, defoliation and dehromation, premature yellowing of leaves, the degree of leaves damage burns, the presence, quantity and condition of natural regrowth). This is observation of technogenic transformation of urban ecosystems at the level of organ, organism, population, ecosystem in the semi-natural (parks), artificial (within residential developments) and forest (shelterbelts аlong the roads) ecotopes. We recommended a system of methods: silvicultural taxation, phytosanitary state of plantations, degree of the crown defoliation and leaf dehromation, premature yellowing of leaves, degree of their damage by technogenic burns to diagnose the condition of woody plants within the megacity. It is important to consider the presence, quantity and condition of natural regrowth, as one of the stabilizing factors in the buffer function of ecosystems.
