Khomyak I. Classification and anthropogenic transformation of Slovechansko-Ovruchsky ridge ecosystems

The thesis is dedicated to the results of complex research of the variety of Slovechansko-Ovruchsky ridge ecosystems taking into consideration their classification, differentiation, anthropogenic transformation and scientific principles of protection. The basis of ecosystems classification is formed by the research of syntaxonomic variety of vegetation groups and environmental conditions with the help of sinphytoindication methods. Anthropogenic transformation is determined by the original methods of estimation of hemeroby indices. Floristic classification of vegetation is detailed. It is represented by 163 associations and communities of corresponding level together with 6 subassociations and variants, which are united in 66 alliances, 46 orders, 27 classes. Detailed classification of natural and man-made ecosystems was created. It consists of 170 units - VII level, 106 - VI level, 68 - V level, 57 - IV level, 35 - III level, 20 - II level, 7 - I level. Ecological and созологічна estimation of region ecosystems is made. 9 landscape ecosystems, which are equal to tracts, are determined. List of rare ecosystems is made. Allocation of kernels and buffer zones of international econet and components of Central-Polissya bilateral biosphere reservation is offered.
