The object of the study is the materials of aerial photography obtained with the application of an unmanned aerial vehicle (UAV) DJI Phantom 3 Advanced and processed by Agisoft PhotoScan Professional Edition software. The objective of the present research is to study the feasibility of the data obtained by innovative photogrammetric methods for monitoring and analyzing the agrolandscapes nanorelief as well as for the design of agrolandscapes in adaptive landscape farming, to identify the possibilities of assessing the occurrence of erosion and make a forecast of their development in the study area using photographic plans. In the course of the work, methods and means of obtaining aerial photographs of a site in the Voronezh region were considered. The altitude map and orthophotomap resulting from image processing were analysed. It has been revealed that such digital models make it possible to study and analyze the state of the surface of agrolandscapes up to the smallest forms of nanorelief both visually and with the application of mathematical characteristics. However, deficiencies in the accuracy of the obtained plans along the edges of the shooting area were noted and the methods for solving the problem of inacuracy were proposed.

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.
