Yakubenko B. The natural fodder lands of the Forest steppe of Ukraine (flora, vegetation, dynamics, optimisation).

In the thesis from the positions of the system approach it is firstly given the results of the flora and vegetation research of natural fodder lands of the Forest steppe of Ukraine, their dynamics and optimisation in the antropogenesis conditions. It is established the quantitative and qualitative composition phytocoenofund of the natural fodder lands of the Forest steppe of Ukraine. The main basis of this phytocoenofund is foremed of the meadow floristic complex. The biomorphology, ecology, synanthropic and economic analysis of the flora is given. The classification of the natural fodder lands of the Forest steppe of Ukraine on the dominant basis is made. The meadow vegetation is the most widespred. Their pecularity is the presence of galophyte meadow. The dynamics tendensis of the vegetation is established. On the basis of it the changes of the natural fodder lands vegetation is forecast. It is revealed in the main role of the degradaion changes, which are in the substatial measure lead to the synantropization of the ecotops and define the future vegetation coenosis. Firstly the theoretical principles of fititing of gramineous-fabaceous species for forming of the plant coenosis on the base of the natural phytocoenosis are given. The original method of optimization of the natural fodder lands coenosis in the antropogenesis conditions.
