PROFESSOR VOLODYMYR KUCHERYAVYI SCIENTIFIC SCHOOL OF URBOECOLOGY, PHYTOMELIORATION AND LANDSCAPE ARCHITECTURE

Introduction. The theoretical foundations of the new ecological disciplines "Urban Ecology" and "Phytomeliora-tion" were laid in the mid-80's and 90's of the last century at the Department of Ecology and Landscape Architecture of the Ukrainian National Forestry University, which at that time was headed by Lviv scientist Volodymyr Kucheryavyi famous by his monographs “Green Zone of the City” (Kyiv: Naukova Dumka, 1981) and “Natural Environment of the City” (Lviv: Higher School, 1984).Purpose and methods. The methodological basis of urban ecological research is the ecological-comparative method, which involves gradation ordination with the allocation of four ecological and phytocenotic zones on the territory of cities into the study of the urban ecosystem (suburban forests - city parks – public gardens - street plantings) (V. Kucheryavyi, P. Hnativ, M. Kurnytska, N. Siroochenko, N. Stepanyak, K. Myronchuk, T. Pushkaryova, Yu. Kozak) This approach is used in dissertation research not only by graduate students and applicants of the Department of Ecology and Landscape Architecture of UNFU, but also young scientists of Kyiv, Lutsk and Chernivtsi.Results and discussion. Taking into account the growth of the "recreational boom" among urban residents in the 80's and 90's, scientific researches of park and forest park phytocenoses are developed (V. Kucheryavyi, A. Zhyrnov, Yu. Khrystuk, R. Danylyk, V. Kramarets, N. Lukyanchuk, O. Kaspruk, R. Dudyn, N. Imshanetska, N. Kovalchuk, S. Marutyak, O. Oleynyuk). During this period, visual methods of diagnosing of urban ecosystems state are widely used, which confirm the feasibility of using of ecowedge ordination. The influence of complex urbogenic gradients of the environment on the adaptation processes of living organisms and their significance for the evaluation of the results of woody plants introduction into the urbogenic environment was determined (V. Kucheryavyi, M. Kurnytska, O. Kaspruk, O. Gorbenko, M. Les, V.S. Kucheryavyi, T. Shuplat, N. Gotsiy). Electro-physiological methods of impedance and polar-ization capacity measuring, fluorescence of plastid pigments, temperature gradients of the environment are used for establishing the level of plant viability (V. Kucheryavyi, H. Krynytskyi, V. Mokryi, A. Kuzyk, M. Hozdog, S. Hridzhuk, Yu. Pankivskyi, V. Kucheryavyi, T. Shuplat). Investigations of the phytogenic field of vegetation begin, its role in the formation of the continuum in conditions of urbogenic and manmade
