Using the method of relief plasters to highlight potentially erosion-hazardous areas on agricultural land

Abstract

With the strong development of soil erosion, land fertility decreases, crops are damaged, ravines turn agricultural land into uncomfortable land and make field cultivation difficult, siltation of rivers and reservoirs occurs. In this regard, issues of land protection from erosion are relevant. The article discusses the issues of identifying potentially erosion-hazardous lands using the method of relief plasters, previously used in landscape science. This method allows to facilitate the identification of destructive processes at an early stage of development and to prevent them in advance. The location of the zones identified by this method (morphoisographs), and their dynamics, characterizes the changes associated with ecological-landscape measures, for example, planting of forest belts, afforestation of ravines and, accordingly, redistribution of surface and underground waters. A morphoisograph, as the line most sensitive to negative phenomena (changes in the chemical, biological, and mechanical composition of soils, soil erosion, etc.) can become the main criterion for identifying potentially unstable zones. The authors highlighted agricultural land that is potentially unstable to erosion. The introduction of a morphoisograph into ecological landscape design expands the possibilities of detailed accounting for the development of erosion processes in the future.
