The article discusses the issues of territorial prevalence of colorectal cancer in Saratov. A statistical analysis of morbidity and an oncogeographical analysis of urban landscape sites were carried out. The study of the regional features of the spread of this pathology, taking into account risk factors, will help in the development of the direction for the active search for patients.
Based on the results of the historical experiment of the CMIP5 and CMIP6 projects, the effectiveness of the scenario estimates (RCP/SSP1 2.6, RCP/SSP2 4.5 and RCP/SSP5 8.5) of the future air temperature for Central Africa for the IPSL and BCC global climate models is evaluated and the simulation results of these projects are compared with each other and with the observations of meteorological stations in the region, both for the historical experimental period and with the observations of recent years for the implementation of future climate projections.
Quantitative assessment of the territory continentality is an urgent task, because in the conditions of climate change, the index of continentality can be taken into account when developing geographical forecasts of landscape development. The purpose of this study is to assess the change in the index of continentality of Western Siberia in the conditions of the current trend in climate development. The statistical series of observations on seven meteorological stations in Western Siberia served as the information base of the study.
The article is devoted to the analysis of the ways of using and accessing the Internet. In the course of the study, a sociological survey of respondents living in the city of Saratov was conducted, the results of which were compared with the average Russian statistical data.
The analysis of changes in the near-surface air temperature of the Northern Hemisphere is given. To identify years in which there was a violation of the series homogeneity, the stepwise trend method was applied using Kolmogorov statistics. It is shown that the identified homogeneous climatic intervals basically correspond to the natural climatic periods of the state of the Earth’s climate system. The assessment of the significance of temperature changes in homogeneous climatic areas was carried out by the method of confidence intervals using Student’s t-test.
The article presents the study results of the annual variability of thunderstorm activity at nine climatic stations in Western Siberia over a fifty-year period from 1971 to 2020. The study revealed a complex quasi-periodic structure of thunderstorm activity series with the most pronounced amplitude of 7–8-year cycles for the forest-tundra and a 2–4-year cycle for the taiga zone, as well as forest-steppes.
The article discusses the issues concerning historical reconstruction of trade and transport system of the Golden Horde based on the data analysis with the use of geographic information systems, logistics modeling and interdisciplinary technologies.
The aim. Study of the ecological state of the Voronezh reservoir under conditions of “blooming” of water by cyanobacteria. Materials and Methods. EEvaluating water quality data of hydrochemical analysis, assessment of suspended solids distribution and temperature in the water area, materials of hydrobiological study (phytoplankton), microcystin content in water have been taken into account. Results and Discussion. The direction of anthropogenic changes occurring in the ecological state of the reservoir has been traced for 2016–2022.
The article presents the influence analysis of industrial enterprises of the Volgograd region on the state of atmospheric air in the region. The importance of solving the problem of greenhouse gas emissions into the atmosphere at the international level has been analyzed. Foreign experience in terms of reducing carbon dioxide emissions of industrial enterprises is considered. A method to reduce the environmental burden on atmospheric air by decarbonization, i.e. сarbon capture and storage of CO2 in deep geological objects is proposed.
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.
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.
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.
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.
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.
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.
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.
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.
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.
