An ecological analysis of the composition and condition of woody plants in urban and suburban ecosystems of the Khopyor River Region

Abstract

The aim: to perform research of the species composition and condition of urban and suburban ecosystems of the Khopyor River Region. The route method was used for the species composition of woody plants. Also, using this method the conditions of the growth of trees and shrubs were described. The data of field ecological observations and researches were analyzed in the laboratory conditions. Plant species were identified by means of determinants. The geographical analysis and floristic belonging of plants in towns and villages is carried out. A diagnostics of the vital state of woody plants is carried out according to the complex of their external signs on ecologically different territories. It is found that the greatest species diversity is characterized by the family Rosaceae Juss. The poverty of the species composition of woody plants in the towns and villages of the research area is associated with insufficient introduction. The largest number of species of trees and shrubs in urban areas are characterized by parks and squares. Of great concern is the weakening of the vital condition of woody plants in the area of suburban highways. The greatest values of damages of the objects of the research are revealed at wood plants as part of roadside territories of towns and villages. The expediency to restore greening in ecologically problematic urban areas is obvious.
