Оцінка життєвого стану деревних рослин у насадженнях обмеженого користування м. Кривий ріг

Abstract

Abstract. Optimization of species composition and improvement of the
vital state of the arboreal planting of industrial cities is possible on the condition
of introduction of new decorative, tolerant to anthropogenic influence plants,
taking into account the compliance of their ecological and biological properties
and decorative qualities with the conditions habitat conditions.
Objective – estimation of the living conditions of wood plants of in
plantings restricted using of Tеrnivskyi district of Kryvyi Rih. Determined taxation indicators, conducted estimation of the state the top of trees and vitality of arboreal plants, were determined.
It was determined that in in plantings predominated by trees of the second
(59%) and third (29%) of the class of height. The smallest number is represented
by a group of trees of the first class (the individual species of the genus Populus
L.). In 40-60 years the trees slow down growth processes, except for Acer
platanoides L., which has such a feature in the 50-60 years. A constant growth
has characterized the individuals of a species of the genus Populus. In the age
group over 60 years old the largest morphometric parameters were
characterized by species of the genus Populus, the smallest – individuals of Tilia
cordata Mill. Further study of the peculiarities of the development of woody
plants in the conditions of Kryvorizhzhya will contribute to the creation of
sustainable and durable plantings in the urbanized areas of the steppe zone of
Ukraine.
Keywords: urbanodendroflor, Kryvorizhzhya, morphometric parameters,
