Marchuk Y. Peculiarities of high productive oak plantations forming in the conditions of left bank forest-steppe zone

The spatial-functional organization of Oak-tree forest ecosystems is the object of study. The aims of study are the assessment of contemporary condition and productivity level of Oak cenosis, their spatial-functional and ecological peculiarities in the condition of regulated forest management, and to define ways of their effective and complete reforestation by using of permanent Oak forest seeds base. The researches were carried out in pursuance of generally accepted methods with certain additions. For the first time quantitative and qualitative parameters of Oak forests dynamics in the region of study were obtained and reserves of their biological resistance productivity were determined. The directions of reforestation processes under the complex of factors influence were determined and ways of native forest stands regeneration were developed. Also peculiarities of different-aged Oak forest stands functioning in the condition of limited forest use were determined. Contemporary condition of Oak forestseeds base were studied and most perspective plus-trees were selected. The implementation -in growing of high productive Oak stands. Sphere of application - forest management.
