Journal Title: Питання біоіндикації та екології - Year 2018, Vol 23, Issue 1
Abstract
The tree planting of ravines plays an important role in the termination of soil erosion processes, and also has a great environmental and recreational value. The dendroflora of the Lyubymivska ravine and the ravine forest belt is represented by 32 species. One of them belongs to the phylum of Pinophyta (Pallasov's pine), others belong to Magnoliophyta (the most numerous families of Aceraceae, Rosaceae, Ulmaceae, Fabaceae). Introduced species dominate – 53.13 %. In the thalweg of the ravine grow trees of the age of about 60 years of such species as Acer negundo, Robinia pseudoacacia, Ulmus laevis, Fraxinus excelsior. Acer negundo prevails, the vital state of it is estimated to be weakened. The underbrush of thalweg is represented by Sambucus nigra, Acer campestre, Ligustrum vulgare, Cornus alba. The undergrowth is very dense and it is represented by Morus alba, Celtis occidentalis, Fraxinus excelsior, Robinia pseudoacacia, Gleditsia triacanthos, Acer negundo. The most diverse dendroflora is in the upper third of the slope of the northern exposition. Following species grow there: Quercus robur, Acer negundo, Robinia pseudoacacia, Morus alba, Ulmus laevis, Armeniaca vulgaris, Celtis occidentalis, Pyrus communis. The underbrush consists of Crataegus monogyna, Sambucus nigra, Acer tataricum, Elaeagnus angustifolia, Elaeagnus argentea. The undergrowth is represented by Celtis occidentalis, Acer negundo, Pyrus communis.The slope has a great angle of bank (up to 40°). Celtis occidentalis, Acer negundo, Robinia pseudoacacia, Ulmus laevis, Pyrus communis, Morus alba grow on the slope of the southern exposition.The undergrowth is represented by Acer campestre and А. tataricum, Cornus alba, Sambucus nigra, Crataegus monogyna. On both slopes there is Ailanthus altissima, which is charactiresed by good recovery and a high vitality index. The total area of all species of erosion plantations of the ravine is 10.5 hectares, but timber trees are only 50 units. The total area size is 1450 m3. The age of trees of the plantation varies from 60 to 95 years. The highest average height is of Robinia pseudoacacia (24 m). Near the slope of the southern exposition of the ravine there are pure plantations of Quercus robur and Pinus nigra subsp. Pallasiana. The woody vegetation of the ravine includes such honey plants as Robinia pseudoacacia, Acer campestre, Elaeagnus angustifolia, Pyrus communis, Armeniaca vulgaris, Ligustrum vulgare. Проведено аналіз біорізноманіття дендрофлори балки Любимівської і прибалкових насаджень Дніпропетровського лісгоспу. Встановлено, що дендрофлора представлена 32-ма видами. Найбільш цінні види – дуб звичайний, сосна Палласова. Встановлені основні таксаційні показники насадження: середній діаметр, висота, запас, бонітет. Наведенірекреаційні характеристики виділів, на яких розташована балка, а саме: клас пішохідної доступності, ступінь регресії, естетична и рекреаційна оцінки.
