Abstract

Results of soil-erosive monitoring according to a system effectiveness of contour agriculture (Russia, Belgorod region, a watershed of the small river) are submitted. The system of adaptive-landscape agriculture provides a number of measures on prevention of water erosion on slopes, to restoration of fertility of soils, increase of efficiency and rationalization of their use. Such measures are construction of hydrotechnical structures, planting of forest belts, a continuous aforestation of gullies.

Modern methods of land maintenance of erosive monitoring of boundaries of regulation (the shaft-gutters combined with forest belts), geoinformation systems (GIS), thematic mapping and remote sensing are used at carrying out on a field stationary and laboratory researches. Materials of long-term supervision which speeds of spring erosional losses of soil in system of contour agriculture assess, can be useful to calibration erosional models. Prospects of closer coordination of design decisions on soil conservation and ecological arrangement of agrolandscape with positionally-dynamic landscape structures of reservoirs are shown. It is developed model dependence of the deepness of the humus horizon on the time for definitions of soil loss tolerance level. It has allowed to reveal dependence of intensity and a direction of horizontal materially-power streams, in particular soil erosion, from a complex of an environment. It is shown, that a task of maintenance of reproduction soils and their fertility is considered in a context of reorganization agrolandscapes and the adjacent lands with it.
