Achasov A. Soil and geoinformation foundations of anti-erosion optimization of agrolandscape: theory and practice

Object - anti-erosion optimization of agrolandscape. Purpose - providing the anti-erosion optimization of agrolandscape the spatial information about the parameters of soil erodibility. Methods - model and laboratory-analytical researches of soils; geoinformation methods of analysis of cartographic and aerospace materials; mathematical design of processes of erosion. Novelty - first scientifically founded conception of soil maps creation, being based on the integral use of four methods of receipt of spatial information: geoinformation analysis of relief; remote sensing of soils; geostatistical methods of discrete data; traditional methods of soil investigation. Results of researches. The algorithm of the automated large-scale drawing a map of soils is developed on the basis of quantitative integral analysis of topographical materials, information of the remote sensing and archived soil maps. The use of these methods is promoted by informing of the created soil maps, exactness of mathematical design of erosion and reliability of the anti-erosion planning of agroland-scapes. Results of researches are employed in the practice of crop production and research activities. Branch - agricul-tural sciences.
