Klymenko Y. Ecologo-biological basis of the restoration of old parks in Polissya and Forest-Steppe of Ukraine

Objects of the research are old and particular modern parks of Polissya and Forest-Steppe of Ukraine. The goal of the research is to identify landscape and phytocenotic structure plus the composition of species of the old parks of Polissya and Forest-Steppe, also to find out their dynamics in space and time, to develop eco-biological grounds and methodological recommendations on how to reconstruct plantations considering a historical aspect. Research methods are: dendrological, landscaping, taxational, phytocenotic and the method of the comparative ecology. Scientific originality: interchange vectors of garden-park landscapes and plantations of parks in Kiev and old parks of Polissya and Forest-Steppe have been found out subject to the types of floral complexes those parks were based on during their creation which are: formations of Querceta roboris and Pineta sylvestris, greenery of floodplains and intrazonal greenery (Alneta glutinosae formation woods), also orchards. Present plantation composition of parks of Polissya and Forest-Steppe has been found out; tendencies of its interchanges have been found out as well. A relation between types of garden-park landscapes and taxonomical composition of plantations has been found out. A concept of the landscape degradation of park associations has been introduced, nature of phytocenotic degradation has been revealed subject to types of garden-park landscapes and native species usage involved in creation of those landscapes. It has been shown that phytocenotic analysis should become the basis of old park plantation reconstruction plans development. Field of application: park design and gardening.
