Abstract
Water soil erosion is one of the most dangerous process which eventually leads to a loss of soil fertility and landscape degradation. The solution to this problem lies in the creation of mathematical models of adequate soil flushing. The current level of geographic information technologies make it possible to perform spatial modeling of soil erosion for different scale areas. To estimate adequacy of spatial model of soil washing off is possible on the basis of comparison of calculation information with the separate factors of erosion of soil measured in the field terms. Methodic. The estimation of adequacy of spatial model of soil washing off was executed on the slope of beam of north-eastern display, within the south part of Podol’ska hills. The soil washing off was estimated using spatial GIS-realized model of water erosion loses and accumulation of soil, developed on the department of physical geography and nature use of the National Mechnikov’s University of Odessa, physgeo_onu@ukr.net Finding. Comparison of the calculated values of annual rate of soil erosion, taken from digital maps of normalized relative to the average for the two periods of research in the area of mechanical cohation soil values generally show good correspondence of. And comparison of calculated annual soil erosion standards of humus horizon showed also close enough to reverse connection between these two sizes.Results. Checking of the adequacy of spatially distributed GIS model of soil flush-accumulation using data from field measurements of some factors of soil erosion showed sufficiently high adequacy of this model.
