Kotovych O. Ecological and hydrological features of forests of steppe zone of Ukraine (by the example of Prisamar'e Dnieper).

The objects are the moisture in the steppe and forest biogeocenoses. The aim is to determine the basic laws of water regime in natural and artificial forests of steppe zone of Ukraine by the example of Prisamar'e Dnieper. The methods are hydrodynamic, water-balance - soil hydrological, measuring and listing taxation, chemical analysis, statistical. The ecological and hydrological features of forest biogeocenoses under the conditions of the steppe zone of Ukraine were investigated. The main indicators of groundwater regime were defined - the intra-annual, seasonal and diurnal structure of the level regime, the starting terms of groundwater deduction by forest biogeocenoses. On the base of hydrodynamic analysis of groundwater level regime the main parameters of balance were estimated - the infiltration supply, lateral inflow and outflow, physical and physiological evaporation. Application spheres are hydrological zoning, protection of forests.
