Historical landscape structures of the eastern part of upper Medzibodrožie region

Landscape represents a specific part of the earth's surface, while it has its own structure – primary, secondary and tertiary. The secondary landscape structure consists of elements of land use and material creations of man, which currently fill the earth's surface. The aim of the paper is to evaluate, based on the analysis of historical military and topographical maps, the changes in the secondary landscape structure in the area formed by the cadastral territories of selected municipalities in the eastern part of Upper Medzibodrožie Region. On four maps showing selected territories of Upper Medzibodrožie Region, we compare extensive changes that have occurred in the landscape structure mainly as a result of human intervention in the landscape structure. Historical maps show that the use of the Upper Medzibodrožie Region landscape has changed significantly over the past 150 years. River regulation, drainage works, deforestation and also the transformation of agriculture had a major impact on these changes. The results show that the largest decrease in area representation was recorded by forests and the largest increase by arable land.
