Abstract
The purpose. Assessment of soil-water protection agrolandscape on hydrological indexes with adaptation of erosionpreventive arrangement in drainage area. Methods. Laboratory-field (takeoff of soil samples, their structurallyaggregation analysis, determination of the content of humus, moisture content, erosion-preventive sustainability), mathematicalstatistical (correlation, fractional error), simulation of agrolandscapes. Results. Operation of agrolandscapes is determined by hydrological parameters of soils and environment (firmness of build of soil, deposits, quotient of protectvie effect of woodland belts, agricultural background). The outline model of optimization of soil-water protection agrolandscape is developed with differentiation on natural-anthropogenous groups in view of deficiency of moisture (from 0,7 NV, %). Conclusions. Assessment of agrolandscape can be conducted according to watering of soils. Complex empirical model of stores of general moisture (mm) in soil for vegetation period of crops in view of influencing factors (rainfall amount — 61,4%; firmness of build of soil — 17,1; agricultural background — 14,6, quotient of protective effect of woodland belts — 4,2%) is the basis of natural-anthropogenous group of agrolandscape.

Key words: agrolandscape, agricultural background, simulation, watering, optimization, factors, methods, quotient, deficiency.
