Pyatkova A. The Spatial Modelling of Water Soil Erosion as the Basis of Scientific Justification of the Rational Use of Erosion Dangerous Lands

An object - the slope erosive system of agrolandscapes of Forest-steppe and Steppe of Ukraine; a target - the development of methods of spatial modeling of soil washing off for the rational use of lands; the methods - model supervisions; cartographic; statistical; geoinformatic modeling; imitation modeling; the results - the spatial hillside changeability of soil resistance; the method of account of spatial hillside changeability of hydrometeorological terms of the thundershower soil washing off; the spatial model of washing and accumulation of soil; the realized spatial model of the productivity of agricultural cultures; the realized model of the rational use of erosive-dangerous lands; a novelty - the analysis of logic mathematical model of washing soil off is executed; the method of account of spatial hillside changeability of hydrometeorological terms of the thundershower washing off is developed; the quantitative estimation of spatial hillside changeability of soil resistance is executed and the connections of this changeability are set with character of surface, erosion and humidity of soil; the spatial model of washing-accumulation of soil is developed; the model of the rational use of erosive-dangerous earths is realized; a degree of introduction - it is embedded; a branch of using -Ministry of agrarian policy of Ukraine, the organs of the landed cadastre and organization of the use of land, agricultural enterprises.
