Abstract
This work presents research data on pasture ecosystems vegetation in south-east Ukraine. This survey was carried out during 19982011 by route and semi-permanent methods. All botanical and geographical chorions of lower level within the territory of our region were explored. The representation of vegetation formations and associations were studied in following pasture steppe ecosystems: watershed ecosystems with differentiated black soil (43 formations, 425 associations), ravine-gully ecosystems with eroded black soil (81 formations, 750 associations), ravine-gully ecosystems with eroded to granite black soil (48 formations, 293 associations), ravine-gully ecosystems with eroded to limestone black soil (39 formations, 355 associations), above flood-plain terraced ecosystems with cretaceous soil (46 formations, 220 associations), above flood-plain terraced sandy ecosystems (24 formations, 140 associations). It is shown that syntaxonomic diversity of natural pasture ecosystems vegetation is dominantly represented by 1029 associations and 178 formations (37% and 33% from associations and formations of regional native vegetation). As far as steppe ecosystems are concerned, 920 associations and 147 formations are registered (33% and 27% from associations and formations of regional native vegetation). As for meadow ecosystems, we registered 424 associations and 80 formations (15% and 14% from native associations and formations, respectively). The highest syntaxonomic diversity is characteristic of ravine-gully ecosystems on eroded to loess black soil, the lowest diversity of all the steppe ecosystems is reported for above flood-plain terraced sandy steppes. Among meadows, vegetation of salt and marsh meadows has the lowest diversity.
Highlights
The work deals with the structural features of the local floras disturbed ecotopes as integral components of a higher rank flora
The local flora is disturbed ecotope, as a collection of species growing in a certain area, the degree of responsiveness to anthropogenic impacts structurally divided into elementary components, the selection of which is based on ecological and botanical features of the plants composing them
Для степных экосистем отмечено 920 ассоциаций и 147 формаций (33% ассоциаций и 27% формаций естественной растительности региона), для луговых – 424 ассоциаций и 80 формаций (15% и 14% соответственно)
Summary
СИНТАКСОНОМИЧЕСКОЕ РАЗНООБРАЗИЕ РАСТИТЕЛЬНОСТИ ПАСТБИЩНЫХ ЭКОСИСТЕМ ЮГО-ВОСТОКА УКРАИНЫ Установлено, что синтаксономическое разнообразие растительности природных пастбищных экосистем на доминантной основе представлено 1029 ассоциациями и 178 формациями, что составляет 37% и 33% ассоциаций и формаций естественной растительности региона.
