«HADIATSKYI» REGIONAL LANDSCAPE PARK FLORA GEOGRAPHIC STRUCTURE (POLTAVA REGION)

Abstract

The article contains results of «Hadiatskyi» regional landscape park flora geographic structure due to the nature of species distribution in the latitudinal (zonal), belt (oceanic continental) and regional aspects, in accordance with the approaches of G. Moisel with co-authors. «Hadiatskyi» RLP flora is characterized by predominance of relatively wide floristic areographic types. According to zonal characteristics there distinguish 16 types, with predominance of species representing submeridional-temperature (177; 18,7 %) and submeridional-boreal (134; 14,2 %) areasamong them. The core of the park florais formed with species ofsubmeridional-temperature, meridional-temperature, submeridional-boreal, meridian-boreal, sub-temperature boreal areas, which make up 64% of the species diversity of the region flora and determine the flora floristic-zonal accessorynature. Climatic features of areas of the region flora are dominated by species with habitats tending to regions with a higher degree of oceanic climate. According to regional confluence and length of areas, there is species of European-Asian (383; 40,5%) and European (221; 23,3%) ranges dominance. The European-Asian group composition is much dominated by species with the European-Western-Asian distribution (195; 20,7%). Among the species whose habitats are associated with Europe, widespread species of European type (195; 20,6%) predominate. In general, geographical structure of «Hadiatskyi» regional landscape park flora corresponds to the western European steppe and steppe flora.
