Insoluble remains of Lower Permian sylvinite rocks in the western and north-western framing of the Caspian depression

The paper presents the results of a study of the insoluble residue of sylvinites and sylvin-halite rocks of the Lower Permian halogen formation, common within the Perelyubsky areas (Western and Eastern), promising for industrial development (Saratov Region) and the Gremyachinsky potash deposit (Volgograd Region). A technique for studying the insoluble residue of sylvinites is presented. The types of insoluble residue are distinguished according to the form of occurrence in sylvinites and its mineral composition is characterized.

Principles and methods for studying the structure of metageosystems for designing a pilgrimage-tourist cluster

Introduction. The article characterizes the spatio-temporal structure of metageosystems of the pilgrimage-tourist cluster “Sanaksar – Temnikov”, located in the center of the Russian Plain, in the zone of interaction of forest-steppe and forest geosystems. Materials and methods. The structuring of information within the framework of the study is based on the simultaneous use of a natural sequence of involving interrelated principles: genetic, historical, systemic, territorial-structural.

Synoptic conditions for the formation of thunderstorms with heavy rainfall over the territory of Western Siberia

The article presents the study results of thunderstorm activity with rainfall over a large territory of Western Siberia in its three regions: Northern, Central and Southern over a seven-year period from 2017 to 2023. The study revealed the most favorable synoptic conditions for the formation of thunderstorm activity with heavy rainfall over a large area of Western Siberia. Cases are also reviewed and factors that need to be paid attention to when forecasting thunderstorms with squally winds are identified.

Pilot innovative territorial clusters: Spatial differentiation, patterns of development and efficiency

The article is devoted to the study of an important component of innovative infrastructure – pilot innovative territorial clusters. The main stages of their formation were considered, spatial patterns of development, structure and economic efficiency were identified and analyzed.

Changes in transport use in Russian urban and rural settlements of different population sizes over the period 2014–2022

The aim of the study is to examine the dynamics of transport use and transport service in urban and rural settlements of Russia with different population sizes in 2014–2022. The hypothesis of the study is that the dynamics of transport use and transport service in rural settlements repeats the dynamics of transport use and transport service in urban settlements with a certain time delay.

Intraannual and interannual changes in clouds in Ufa

The study of cloud cover and its characteristics (quantity and forms) is of practical interest, especially for large cities. Cloud cover, having a dual effect (albedo and greenhouse), is an important factor in the formation of the thermal regime in the conditions of global climate change. This article presents the results of the analysis of daily, annual and long-term changes in the cloud cover regime in the city of Ufa(Republic of Bashkortostan). Urgent data from long-term observations of clouds (1966–2020) were used for the analysis.

Unveiling the evolutionary patterns of Ecistic space in the Saratov region during the latter half of the imperial era (1800–1917)

This study delves into the profound transformation of demographic and Ecistic space within the contemporary Saratov region during the latter half of the imperial era (1800–1917). Spatial and temporal trends, as well as the driving forces behind their development, have been meticulously examined. The findings reveal a fascinating process of Ecistic space metamorphosis within the region.

Space and time in the development of geosystems in Pacific Russia

Introduction. The analysis of geosystems development on the scale of geographic space on the territory within the framework of geographic time is presented. Space and Time are understood together as “timespace”, that is “time-space”. Theoretical analysis. It allows to conclude that there are different categories of Space and Time. A hidden presence in Space and Time was revealed not only in physical, but also in moral categories, within the framework of “Nature – Man; Man is Nature”. Conclusion.

Differentiation of population density within a large city to identify the level of anthropogenic load (on the example of Belgorod)

Residential areas occupy a special place in the planning structure of the city. The building density and the number of floors of houses have an impact on the architectural appearance of the city and the concentration of the population. However, the high population density indicates a significant pressure on the natural framework. The main objective of this article is to show the differences and heterogeneity of population density within the residential area of the city of Belgorod.

Scheming of socio-economic development of Russian regions: Problems of multi-scale scenario planning

Introduction. Regional development in the last year and a half has faced new challenges related to the limitations of foreign economic relations, which poses the task of revising forecasts of socio-economic dynamics in the subjects of the Russian Federation. Such a task can be solved only by applying a deductive approach: combining development scenarios at different taxonomic levels. Theoretical analysis.
