The article presents the results of research the dynamics of the length of the channel network of elementary watercourses within the territory of the catchment area of the Birlya river in the XXI century. The researched area is located in a zone of broad-leaved forests and characterized by high anthropogenic pressure on the landscape (high plowing and relatively high population density). The research is based on the materials of expedition work, carried out in the summer of 2020 and on geoinformation analysis of topographic map data. As a result of field work, the current position of the sources of elementary watercourses was realized, and the change in the length of rivers was calculated by comparing the position of it’s sources in 2001, recorded on topographic maps, with the position of the sources of rivers in 2020. Established the fact of multidirectional dynamics of the length of the channel network of elementary rivers in comparison with 2001 and the significant role of local conditions that determine this dynamics: the nature of agriculture, forest cover, ploughing, and the influence of animals.

The article contains the results of researching of the dynamics of the length of the channel network of elementary watercourses within the territory of the catchment basin of the Logovezh river in the XXI century. The researched territory is located in the Upper Volga basin in the zone of mixed coniferous-deciduous forests and characterized by high forest cover and swampiness. The research is based on the materials of the expedition work, carried out in the summer of 2021, the data of thematic maps and literary sources, processed using GIS. As a result of field researchs, the current position of the sources of elementary watercourses has been established, the indicator of the change in the length of their channels in the XXI century has been calculated. The fact of both increasing and reducing the length of the channel network of elementary watercourses with the predominance of their reduction processes has been established. Against the background of the restoration of the landscapes of the researched territory, there is a partial increase in the length of the channel network of elementary watercourses.

The territory of the Sergachsky district of the Nizhny Novgorod region is located in the north of the forest-steppe zone, at the northern extremity of the Privolzhskaya Upland. Due to favorable agroclimatic conditions, the researched territory is characterized by a high degree of anthropogenic transformation of landscapes, mainly involved in agriculture. Areas of broad-leaved forests have been preserved mainly in places, that are inconvenient for plowing – on the steep slopes of river valleys and in ravines. Flat watersheds and sloping slopes have been plowing for several centuries. Thus, the landscape features of the territory traditionally determined the type of economic activity and its territorial boundaries, but often land use planning was carried out on an intuitive level, based on the experience of life in the landscape, but not on a systematic account of the specifics of its components. The long-standing and intensive economic pressure has led to a reduction in forest cover, a decrease in biodiversity, the development of erosion processes, and the degradation of soil cover. Further development of the economy in the researched area requires the adoption of well-thought-out decisions, based on the results of geosystem analysis. During solving problems of territorial planning, nature management, implementation of environmental protection measures, the most effective is the use of a landscape approach. However, until the present, the scheme of landscape differentiation of the territory of the Sergachsky district at the hierarchical level of landscapes has not been developed. The article presents the results of landscape zoning of the territory of the Sergachsky district of the Nizhny Novgorod region, performed on the basis of field research, analysis of maps, literature sources and remote sensing data processed using GIS. The presented results are the basis for making management decisions in the researched area.

The article presents the results of landscape differentiation of the territory of the state nature sanctuary “Sursky Peaks” (Ulyanovsk region), performed at the hierarchical level of landscape types. The researched territory is located in the forest-steppe zone (northern forest-steppe subzone) within the Volga upland. The territory is characterized by high biological diversity. The high environmental significance determines the relevance of the landscape zoning scheme, which is necessary for the effective organization of environmental and recreational activities. During the research, 4 landscapes were identified, for each of which a list of characteristic stows was established, areas of violations of the environmental regime – clearings – were identified and mapped. The work was carried out on the basis of field researches, conducted in 2021, materials of remote sensing of the Earth, thematic maps, literary data processed using GIS.

The territory of the watershed basin of the Birlya River is located in a zone of broad-leaved forests, characterized by high anthropogenic pressure on the landscape (high plowing and relatively high population density). These circumstances determine the high demand for the landscape zoning scheme, which is necessary for the effective organization of environmental and recreational activities. The article presents the results of landscape differentiation of the territory of the watershed basin of the Birlya river of the Republic of Tatarstan (Russia), performed at the hierarchical level of landscape types. The work is based on the materials of the field research, conducted in the summer of 2020. During the research 5 types of landscapes were identified.
