“Phytocoenotic
structure of park plantations of Lviv region and the guidelines of their
improvement”
Scientific
novelty of the work
For
the first time in the conditions of Lviv region the structural special
features of park phytocoenoses have been investigated and generalized, in
particular the special features of the formation of hipersynusias under the
canopy. Two
new plant associations of park vegetation
Geum
urbaneti-Aceretum
pseudoplatanoidis and Sambuco
nigrae-Aceretum
pseudoplatanoidis
and
eight types
of
hipersinusias by edificator species
have
been singled
out. The
appreciation scales
of dominant, tolerant, and exploratory
properties of park wood and brush species have been elaborated.
The
ecological-coenotic strategy for 90 species
of wood and brush plants in park phytocoenosis has been proposed
and the table model of development of park flora
in the course of time has been built.
On a basis of this research the guidelines to the evolution prognosis
of park phytocoenoses
and to the improvement of their structure have been proposed.
