Abstract
In the territory of the central park of culture and recreation of Kamianske there are 1099 specimens of trees that belong to 28 species and 17 families. The plantations are mainly represented by groups. The average age of plantations is about 40 years. Most plants are deciduous, conifers are represented by 3 species – Thuja occidentalis L. and Picea pungens Engelm., P. pungens f. glauca and P. abies Karst. The dominant tree species in the park of culture and recreation are Tilia cordata Mill., which grows in the number of 199 plants (18,10 % of the total number of trees), as well as Aesculus hippocastanum L., Robinia pseudoacacia L. and Acer platanoides L. (15.39; 13.46 and 10.19 %, respectively). Other woody plants are represented in much smaller quantities. There are single instances of Catalpa speciosa War. ex Engelm., Juglans regia L., Sambucus nigra L., Pyrus communis L. About half of all trees in the park are invasive plants (534 pcs or 48.58 %). The vast majority of these plants come from North America (57.49 % of all introduced plants). Families in plantations of the park are represented by 1–3 species, with the exception of Salicaceae Lindl plants and Rosaceae Juss. (4 and 5 species, respectively). The most numerous group are represented by trees, the diameter of which varies from 9.1 to 18.0 cm. These are mostly middle-aged trees. Their number is about one third of the total number of trees in the experimental area – 33.3 %. Following the indicated group in number should be placed specimens, the diameter of the trunk at an altitude of 1,3 m is 27.1–36.0; 36.1–45.0; 45.1–54.0 and 45.1–54.0 cm. With the increase in the number of trees in different diameter groups, the latter can be ranked as follows: 9.1–18.0 > 27.1–36.0 ≥ 36.1–45.0 ≥ 45.1–54.0 = 54.1–63.0 > 63.1–72.0 > 72.1–81.0 > 81.1–90.0 ≥ up to 9 > more 90 cm. The average diameter of the stem in the plantations of the park is about 32 cm. The height of the most numerous group of plants is represented by the group with this index ranged from 15.1 to 20 m. Somewhat less widespread are groups 10.1–15 and 5.1–10 m – 30.5 and 28.1 % to their total number, respectively. Изучен видовой состав и некоторые таксационные характеристики древесных насаждений Центрального парка культуры и отдыха г. Каменское. Установлено, что на территории парка произрастает 1099 екз. деревьев, которые относятся к 28-ти видам и 17 семействам с преобладанием лиственных древесных пород. Около половины древесных насаждений – интродуценты, преимущественно Североамериканского происхождения. Доминирующими видами являются липа сердцелистная, каштан конский, робиния псевдоакация и клен остролистный. Средний диаметр ствола в насаждениях составляет 32 см, у 33,3 % деревьев значения этого показателя варьируют от 9,1 до 18,0 см. Наименьшим количеством представлены экземпляры с диаметром штамба более 90 и менее 9 см – 0,7 и 3,5 %, соответственно. Средняя высота насаждений составляет 13 м.
