Nazarenko N. Structural and typology fundamentals of ecosystems' organization of deciduous woods of Northern Steppe Prydniprovie.

The theoretical fundamentals of woods ecosystems classification and typology have been developed and general theoretical fundamentals of biodiversity and vegetation pattern researching have been characterized. The taxonomy analysis of northern-steppe deciduous woods flora has been realized. For northern-steppe deciduous woods, the scheme of phytoindicative scales and phytoindicators has been elaborated and ecologicaly-coenotic groups and ecomorphs have been founded. The analysis of northern-steppe deciduous woods vegetation has been realized by multivariate statistics methods that permits updating the typology scheme of northern-steppe deciduous woods within the bounds of Belgard's typology. The syntaxonomic study of northern-steppe deciduous woods vegetation has been done by Braun-Blanquet approaches. The status of plant diversity has been characterized The analysis of non-flooded oaks woods vegetation pattern has been done depending on slope vector, profile and exposition, forest conditions and geomorphologic localization. The herbage vegetation patterns structure has been investigated for short-flooded oaks and alder woods, birch-aspen small woods ("koloks") and woods on soloded soils also. The factors of vegetation patterns have been characterized.
