Dendrochronological diagnostics of the state of tree plantations as a way of indicating pollution of an urbanized environment

Abstract

The article presents the results of studies of the influence of anthropogenic factors on the radial growth of Pinus
sylvestris L., Pinus sylvestris and Betula pendula R., and also will be shown the comparative characteristic of stands of trees of
generalized tree-ring chronologies of the northern industrial zone and parks of Pavlodar. As a result of researchers a negative
index is revealed between the radial annual growth of trees and pollution levels of the area has been identified, which makes
it possible to conclude that this indicator can be used to indicate the pollution of atmospheric air in the urban environment.
The obtained models of interrelation of radial growth of trees in the territory of the investigated inndustrial zone can be used
to access the stability of woody plants to extreme changes.
