Abstract

It was investigated the dendroflora’s species composition of green plantations of Karlivka town (Poltava region), including intraurban group consisting of planting sites located within the area of residential and industrial neighborhoods – three parks, square, street and roadside green spaces and planting in the industrial enterprises, schools and kindergartens. It was revealed the eco-valeological role of dendroflora in optimizing the environment of the studied town. As part of the green space of Karlivka town it was isolated the groups of rocks for their functional purpose: dust-adsorbing (Populus tremula L., Quercus robur L., Tilia cordata Mill., Picea abies L., Betula pendula Roth., Acer platanoides L., Fraxinus excelsior L., Sorbus aucuparia L.); nois- insulating (Populus italica L., Salix fragilis L., Aesculus hippocastanum L., Betula pendula, Fraxinus excelsior, Acer negundo L., A. platanoidеs, Syringa vulgaris L.); microclimatic (Quercus robur, Populus italica, Tilia cordata, Salix fragilis, Picea abies, Robinia pseudoacacia L., Acer platanoides, A. negundo, Betula pendula, Aesculus hippocastanum, Fraxinus excelsior). It was founded, that in green spaces of parks and streets of Karlivka town predominant species are the group that least let the solar radiation (0,8-0,9%), because they have a thick crown – Aesculus hippocastanum, Acer platanoides, Quercus robur, Populus italica, Fraxinus excelsior, Tilia cordata and others; species, which have a disperse crown and able to pass most of the sunlight (7,0-9,0%), are Robinia pseudoacacia, Betula pendula, etc. The study established that when choosing and planting trees and bush, do not always take account of their species and varietal assortment, ecological and decorative properties. Based on the results it was identified the areas that are need for reconstruction of landscape gardening.
