Novak A. The condition, productivity and renovation of oak forests given the aerotechnogenic pollution of the environment (the example of the flat part of the western region of Ukraine)

The research object - is the oak forests of Prikarpattya and Western Polissya, which grows in the area of aerotechnogenic pollution by the exhausts from the cement and nitric productions. The research purpose - to find out the degree of degradation, to explore productivity, reproductive potential of oak forests on the flat part of the western region of Ukraine under conditions of aerotechnogenic pollution by the exhausts from the cement and nitric productions and to outline the ways of their recreation. The research methods - forest estimation, comparative ecology, geobotanical, reconnoitering, statistical. The scientific novelty - first for the region of researches the sanitary condition of forest with participation of oak, which grows under conditions of aerotechnogenic pollution is studied. The forestry estimation of productivity of the oak woods and comparative description of productivity of flooded and dry forest stands under conditions of pollution by the industrial exhausts is conducted. New information in relation to fruiting, natural renovation of oak in the technogenic areas of industrial enterprises and influence of the grass coverage on the development of self-sowing and growth of oak is got. The models for changing the radial growth as well as defining the amount of self-sowing and oak in the woods that are subject to aerotechnogenic pollution are developed.
