Abstract
The aim of the article is to assess the results and perspectives of mathematical modeling and calculation of soil erosion as the basis of scientific justification of sustainable land use within the erosion dangerous areas, the object – the mathematical models of soil erosion and the subject – evaluation conformity of these models to the requirements of modern science and practice from terms of being able to use them to justify the rational use of land resources in the natural and economic conditions of the Steppe and Forest-Steppe zones of Ukraine.Presented the periodization of history of mathematical modeling of soil erosion in the world since the late 30-ies of XX century, for each period the characteristics of the main singularities is given. Formulated the requirements to the mathematical models of soil erosion from the standpoint of solving problems on the justification of rational use of erosion dangerous areas based on modern systems of adaptive-landscape and precision farming systems.It is shown that from mathematical models of soil erosion, currently used in Ukraine, to the greatest extent to these requirements corresponds the spatial (2D) GIS implemented physicaly-statistical mathematical model of erosion-accumulation, developed at Odessa National I. I. Mechnikov university. The model sucсessfully passed verification by independent data observations and measurements. However, it needs to be improving, that should go in several directions, including updating the information base, further research patterns of spatial distribution of factors of the erosion-accumulation process and the development of methods of their geo-information modelling.
