Description
The thesis explores regularities of distribution of invasive flora within the roadside landscapes of railways in Kirovohrad region.
The thesis’s structure is determined by the logic of the research, the tasks and consists of introduction, four chapters, conclusions to the chapters, conclusions to the thesis, a list of used sources and appendices.
The first thesis chapter is titled "Theoretical and methodological aspects of research of invasive flora as an element of anthropogenic landscape" defines the place of research of invasive flora in studies of anthropogenic landscape, substantiates the scientific principles of invasive geofloristics – a discipline that should study space principles of formation of the alien flora, methodological grounds and methods of synphytocenological research, their conceptual and terminological apparatus are outlined, stages of research elaboration on phytoinvasions are singled out.
Research in the field of invasive geofloristics is conducted in between several scientific disciplines - anthropogenic landscape science, botany, constructive geography and more. The interdisciplinary nature of research in the field of invasive geofloristics has determined the formation of their methodological foundations, which include the provisions for bio- and geoecology, the doctrine of noosphere, the concept of sustainable development and interaction of nature and society.
General scientific (analysis, synthesis, comparison, deduction, induction) and specific methods (comparative-descriptive, cartographic, zoning) inherent to Earth sciences are used in the research.
Invasive geofloristics is most closely related to geographical and environmental sciences, and to a lesser extent to biological sciences (botany).
The conceptual and terminological apparatus of invasive geofloristics is in the process of making. The key concepts, from which derivatives come, are "adventization", "landscape", "phytocenosis", which have respectively geobotanical, geographical and ecological meaning.
There are three stages in invasive geofloristics development - the initial one (before 1939), the main content of which was issue of the advent flora and the beginning of development of theoretical and methodological principles of its research; mature (1945–1991), during which the theoretical foundations of a new scientific direction were deepened and at the same time the regional component of research was significantly strengthened; modern (since 1991), during which there was a tendency to design research in the field of invasive geofloristics in a separate scientific discipline.
The second thesis chapter - "Natural prerequisites for the formation of invasive flora of railways in Kirovohrad region" outlines the main features of geological structure, relief, climate, hydrography, soils, natural vegetation, and describes the landscapes of Kirovohrad region.
In general, the natural conditions of Kirovohrad region are favorable for plants spread, in particular the migration of species. The location of the territory within the Ukrainian Shield has led to the formation of a flat terrain, which facilitates the movement of seeds and plant organs.
Moderate continental climate of Kirovohrad region promotes fast introduction and naturalization of euribiont species, which, regardless of the conscious will of a human being, come here by rail.
The soil cover of Kirovohrad region, represented mainly by typical and common chernozems, also contributes to the spread of phytoinvasions, especially the penetration of herbaceous plants, the most demanding to soil quality.
The forest cover of Kirovohrad region is insignificant. The predominance of steppe vegetation in aboriginal phytocenoses determines the formation of life-like adventive flora of the region. The invasive flora of the railways is represented mainly by herbaceous plants.
The greatest danger caused by phytoinvasions is uncertainty of the prospects for further spread of rare, in particular Red Book, aboriginal species in Kirovohrad region. The decline in their populations due to agricultural production is exacerbated by spread of invasive species. Therefore, the fight against phytoinvasions is an important component of the overall issue of nature protection.
The natural conditions of Kirovohrad region, on the one hand, are favorable for formation of biodiversity and, on the other hand, create significant opportunities for anthropogenic modifications of biocenoses and landscapes, in particular man-made phytoinvasions.
An important place in making scientific principles of phytoinvasion control belongs to landscape analysis of territory as a tool of geoecological substantiation of prospects for nature use.
