The aim of the study is to identify relationships between the agrochemical indicators of the arable layer (humus content, mobile phosphorus, exchangeable potassium, and pH values of exchangeable acidity), field moisture, and spectral characteristics of soils in order to assess the degree of erosion under the conditions of the Chuvash Republic. The studies were carried out at five test sites (14 sampling points) on sod-podzolic soils, gray forest soils, leached chernozems, and their eroded varieties.

In Belgorod, the nature of environmental pollution sources and associated geochemical flows obeys general patterns. However, the city also has specific natural and climatic characteristics, which determine the scientific relevance of studying soil and ground pollution, as well as its practical significance for Belgorod. To identify patterns in the distribution of pollutants across the city, a pairwise comparison (correlation analysis) of macro- and microelement parameters of soil and ground samples was conducted.

The article addresses the pressing issue of assessing and ensuring the spatial viability of municipalities in the extreme environment of the Republic of Sakha (Yakutia). The research aims to develop an original methodological framework for a comprehensive assessment of spatial viability, tailored to the specifics of northern and Arctic territories. The work analyzes theoretical and conceptual foundations, factors, types, and contemporary methods for assessing territorial viability.

The article examines the nature of changes in the pressure field at the Earth’s surface around the globe during two natural climatic periods ofthe Earth’s climate system –the stabilization period andthe secondwave of globalwarming in July. The pressure fieldwas approximated by the geopotential field of the surface H0. In the northern hemisphere, no differences in the structure of the geopotential field of the H0 surface were found in the two natural climatic periods.

This study analyzes the distribution and status of feather grass (Stipa pennata L.) in the Belgorod region, based on literary and archival sources, as well as a special selective field survey of its habitats conducted in 2023. The survey included 20 key sites across 7 administrative districts and additional locations where the species was found. The results demonstrate a manifold increase in the number of recorded growth sites over the past 100 years.

The genetic approach to the analysis of the formation of the territorial production system of the region can give interesting results. The initial stages of the industrial development of the region are characterized by flexibility in relation to the factors of the economic and geographical location of the production centers. Its analysis provides a deeper understanding of the question why individual cities have been actively developing, while others have experienced only a short-term rise.

Introduction. In the modern conditions of development of the tourism industry, the creation of high-quality cartographic support for routes, which helps to increase their attractiveness and information content, is of particular importance. Retrospective analysis of the study area. The city of Saratov, awarded the title of “City of Labor Valor”, has a rich historical and cultural heritage associated with the labor exploits of its residents during the Great Patriotic War. Data and methods.
