The purpose of the publication is to reveal the content of modern developments of the Department of Landscape Science in the context of the previous research achievements of the scientific unit. The main part of them is presented within four complementary research areas: geoinformation mapping of landscapes, study of anthropogenic changes in landscapes, landscape planning and nature conservation landscape science. The main results of the work in the first of these areas include the creation of a prototype GIS of landscape map of Ukraine at a base scale of 1:500,000, as well as cartographic support for most of the department’s other activities. The research on anthropogenic landscapes changes primarily concerned the study of current state and evolution of radioactively contaminated landscapes of the Chornobyl Exclusion Zone; detection of land cover changes using remote sensing data; generalising works on the methodology of integrated studies of anthropogenic landscapes and a unified classification of natural and anthropogenically modified landscape complexes. Landscape planning is a new research area based on European, in particular German, experience. For 15 years, the Institute of Geography of the National Academy of Sciences of Ukraine, with the participation of the department’s staff, has been adapting it to the conditions of Ukraine by the example of Cherkasy region. This resulted in the introduction of the landscape-planning tool into the regulatory framework for spatial planning and the extension of its practical application to other regions of Ukraine. The department’s studies in the field of nature conservation landscape science covered both theoretical and methodological issues (in particular, substantiating Ukraine’s econetwork formation, determination of approaches to expanding the network of protected areas) and solving a number of practical problems related to many protected areas and objects in different regions of Ukraine. With the outbreak of the full-scale war in Ukraine, the main focus of the department’s activities shifted to researching the impact of the war on the landscapes of Ukraine and substantiating the best ways to preserve and restore them.

Background. The analysis of trends in land cover changes will allow to detect trends in land cover changes, which will contribute to the understanding of the reasons for changes in natural ecosystems and the development of strategies for their preservation and restoration. The analysis of land cover changes can be useful for assessing the impact of anthropogenic and natural factors on land using, which is important for making decisions about the rational using of natural resources, especially in the post-war period. The purpose of the research is to allow to detect the trends of land cover changes in Kharkiv region as a result of hostilities, using the satellite materials and statistical data from open sources. Methods. For the research, materials from remote sensing of the Earth were utilized, including methods of their processing and visualization. M a t h e m a t i c a l and statistical methods were applied to process statistical information and obtain index images resulting from the processing of satellite images and the generation of thematic raster data. The article conducts an analysis of the main trends in land cover changes in the Kharkiv region, highlighting trends for the most significantly altered land cover types, specifically forests and agricultural lands, for the period 2015-2022. Results. A general trend since 2015 has been the reduction of forested areas and agricultural lands, with a significant decrease in 2022, as a result of military actions and their consequences. Land cover degradation due to military activities is currently a prominent trend, representing the primary tendency in land cover changes. As a result of military actions in the Kharkiv region, all natural resources have suffered: lands from pollution and contamination with various types of waste, atmospheric air from emissions due to explosions and fires, water bodies, forest resources, and fauna from enemy equipment, pollution, and deliberate destruction. Conclusions. For a more detailed study of land cover changes related to military activities, especially regarding the destruction of the humus layer, soil pollution with metal fragments and explosive residues, field research and the use of high-resolution aerial or satellite imagery are necessary.

The issue of building thematic maps of erosion dissection, despite its wide demand in various fields of human activity (construction of hydraulic structures, transport and housing construction, agriculture), still has no clear rules and instructions, which causes different perceptions of the obtained mapping results by specialists. The purpose of the study is to experimentally identify the change in the index of erosive dissection depending on the scale of the initial data, the size of the cell, the method of constructing the thematic map, etc. The methods used in this research are the method of mathematical statistics, GIS mapping and modelling, spatial analysis, and change detection. For each of the selected methods of thematic mapping, we compiled the cartograms that allow the visual tracking of changes in the elements of the erosion network depending on the geometric characteristics of the scale and cell size. The dimensions and characteristics with optimal results were substantiated. The main feature of erosional dissection mapping of any territory is to detect the negative relief or concave upward forms. The result is a visual perception accompanied by the addition of numerical values. Estimation of erosion dissection by these methods was used in the construction of a thematic map of the foothill territory with a relatively homogeneous relief pattern. It should be noted that the change in the morphometric index happens simultaneously with the change in orographic features. Therefore, for areas with different forms of relief, the combination or use of only one of the above methods allows identifying the optimal and most accurate one among them. The use of well-established methods will facilitate the study of foothill plains or mountainous areas and will allow expanding the scope of the use of thematic maps for applied purposes and forecasting.
