Gorban V. Ecological role of aeolian deposits in the forming of edaphotopes of forest artificial biogeocenoses of Ukrainian steppe zone.

The objects are edaphotopes of forest artificial biogeocenoses of Ukrainian steppe zone. The aim is to study the ecological role of aeolian deposits in the forming of edaphotopes of forest artificial biogeocenoses of Ukrainian steppe zone. The methods are field ecological-geobotanical, macro- and micromorphological, physical, laboratory-chemical, physical and chemical. In the paper the ecological role of aeolian deposits in the forming of edaphotopes of forest artificial biogeocenoses of Ukrainian steppe zone has been researched. Ecological conditionality of aeolian deposits in forest artificial biogeocenoses has been determined. The main parameters of forest artificial biogeocenoses conditioning intensity of aeolian material deposits have been established. The features of biogeocenological interaction of aeolian deposits with components of forest artificial biogeocenoses have been developed. In A. L. Belgard forestry typological formula it is suggested to use the accumulation coefficient in compacto reflecting features of existing aeolian deposits. Theoretical proposition of geographical and ecological accordance and discordance between aeolian deposits and edaphotopes of forest artificial biogeocenoses has been developed. Findings of investigation of physical and physicochemical properties, content of water-soluble compounds, content of humus and its group composition, micromorphological organization, mineralogical composition, natural radioactivity of aeolian deposits and their influence on edaphotopes of forest artificial biogeocenoses in common chernozems, Azov chernozems and dark chestnut soils are presented. Comparison of influence of aeolian deposits on edaphotopes of forest artifical biogeocenoses of different subareas of Ukrainian steppe zone has been performed. Practical recommendations of aeolian deposits of forest artificial biogeocenoses of Ukrainian steppe zone efficient usage are presented. Application sphere are creation and proceeding in forest artificial zonal, training courses.
