Landscape Organization and Species Structure of the Wood-Shrub Plantation of the Khortytsa National Academy Park in Zaporizhzhia

Abstract

The article presents the results of the study of the species composition of tree-shrub plantations of the Khortytsa National Academy park in Zaporizhzhya and its landscape organization. It was established that the total number of plants in the plantations of the park comprises 260 species, of which 202 are tree plants and 58 are shrubs. On the whole, 28 species of plants belonging to 25 genera and 15 families are noted in the studied territory. Among the woody plants, the most common are Catalpa bignonioides (18%), Betula pendula (14%) and Thuja occidentalis (9%). Families are represented by 1-2 species, with the exception of the families of Cupressaceae (5 species) and Fabaceae, Rosaceae, Oleaceae (3 species). The tree-shrub plantation of the park is created mainly by chaotic landings in the form of arrays and groups. The density of the tree planting in the park is 404 pc / ha, and the density of shrubs is 116 pc / ha. The analysis of the sanitary state of the tree vegetation of the park of the Khortytsa National Academy of Zaporizhzhya showed that out of 202 trees 21.8% belonged to the first category (without any signs of weakening), 40.1% of plants belonged to the second category (weakened), 18.3% belonged to the third (very weakened), 14.4%, - to the fourth (drying up), 2.9% - to the fifth (fresh deadwood) and 2.5%. – to the sixth category (deadwood of the previous years). The discrepancy between the species composition of the vegetation, the ecological conditions of growth and the high density of tree planting does not allow each plant to exhibit its decorative properties in full. All this reduces the architectural and artistic expressiveness and aesthetic appeal of the park. Therefore, the selection of plants for the design of green spaces should be carried out on the basis of generally known principles - ecological, decorative and bio-centric, which will enable to maximize the park environment in aesthetic terms and will give this object a unique look.
