Grytsan Y. The ecological bases of transformational influence of forest vegetation on the steppe environment (ecotop, interaction, dendroindication, typology)

The forest ecosystem in the steppe areas of Ukraine. The substantiating the new scientific direction - forest pertinention biogeocenology. Methods of complex bio-geocenology researches, method of dendroindication, method of mathematical statistician; PC, applied pro-grams "Statistika W v 5. 773", "Matlab 5.1", "MathCad v 7.0 Pro", "Microcal Origin 5.0", "Microsoft Excel 97". The information about physical characteristic of forest ecosystems connected with transformation property of forest in the steppe has been given. The scientific sub-stantiation of natural forest ecosystem usage, as a model for computer methods of forest-field's elaboration and landscape construction in steppe has been presented. The new scientific direction - forest pertinention biogeocenol-ogy - that is a conception about transforming role of natu-ral and artificial forest ecosystems in the steppe areas has been substantiated. Sphere of use are ecology, forest cultivation, forest recultivation of grounds, training course.
