The Zoning of the Ural-Volga Region for Spatial Planning Purposes

The composition of macro-regions in the «Strategy of Spatial Development of the Russian Federation for the Period up to 2025» is considered. The principles of allocation of the macro-region are analyzed from the position of compliance with the approaches of economic zoning. Within the vast territory of the Ural-Volga region, typical and transitional regions are distinguished, morphological features of the settlement system are analyzed, primarily in the river valleys. The conclusion is made about the internal heterogeneity of a number of proposed macro-regions.

To the Complex Geoeclogical Region Zoning Methodology Based on Conceptual Modern Landscape Science Models (Saratov Region as an Example

Modern landscape science, based on polystructural and polyscopic geosystems conceptions, represents the methodological basis for geo-ecological structures complex territorial analysis. The article discusses the landscape-economic (geo-ecological structures) of Saratov Right Bank of the Volga and trans-Volga region and features of morpho-cellated, basin and eco-functional territory models as a basis for creation maps of geo-ecological zoning.

Urban Ecological Aspect in Analyzing the Incidence of a Thyroid Cancer in Saratov

The article provides the experience of joint work of urban ecologists and oncologists in identifying and preventing the thyroid cancer in Saratov. Oncogeographic works were based on the geo-ecological research data, which made possible to determine the most polluted urban landscapes. The medical- geographic analysis was made with the help of using GIS technology. Urban ecological work precedes screening studies. Also, it is the basis of oncological monitoring.

Monitoring of Degradation Processes on Slope Agrolandscapes of Povolzhie Region

The influence of climate change on erosion processes in slope agricultural landscapes is determined. Long-term data (1971–2017) on the study of soil protection methods of the main tillage and their impact on water reserves in snow, melt water runoff, soil washout in the changing climate are presented. It was found that the increase of air temperature, the decrease in the depth of soil freezing led to a reduction in the loss of melt water to runoff and a reduction of erosion.

The Comparison of the Methods of Photogrammetry and Laser Scanning for the Establishment of Three-Dimensional Models of Objects and Territories of Archeological GIS (on the Example of the Archeological Excavation of Uvek Hillfort)

Currently, methods of photogrammetry and laser scanning are available for a wide range of users and have been used to solve various application tasks. One of the most popular and main areas of application of these technologies is creating 3D models of objects and territories. The authors of the article, based on the results of a study of the territory of the Uvek hillfort, carried out the construction of 3D models of archaeological excavation site of 2017 using photogrammetry and laser scanning to create archaeological GIS.

Variability of Tropopause Characteristics in the Arctic According to the Data of Atmosphere Radiosounding

The article presents the results of the polar tropopause study in the Arctic during summer seasons for the period from 2012 to 2017. The variability of tropopause height and temperature at this level are analyzed using data from three Arctic aerological stations.

Monitoring El Nino (La Nina) Events in the Pacific Ocean According to the Satellite Radiometers IKOR-M

This report describes the analysis of space-time distribution of the Earth’s radiation balance components in the Pacific Ocean during El Nino (La Nina) obtained using IKOR-M radiometers at the «Meteor-M» satellite No. 1 and No. 2 are analyzed, as well as the results of their comparison with the data of the sea surface temperature.

Interaction of Natural Factors and Processes in the Organization of Geosystems and their Sustainable Development

Many aspects of «interaction» of factors and processes, being the central ones in any science and constantly marked for their high urgency, have not been sufficiently investigated so far that is also typical of modern natural sciences. The work defines five basic types of factors and processes: gravitational, geophysical, geochemical (including biotic component), anthropogenic/technogenic, and geoinformational. They are separately studied with methodical application of «interpenetrating» research of the geosphere components, i.e.

Zoning of the Saratov Region According to Formation of Protein in Spring Wheat

The article presents forecasts of the quality of spring wheat grain according to the method of V. Ya. Yaroshevsky and V. P.

The Assessment of the Development of Intercity Bus Service in the Saratov Region

A number of aspects of intercity bus service in the Saratov region are considered. Based on the duration and cost of the bus ride from the regional center to the municipal centers, economic distances within the region are estimated. It is concluded that there are significant differences in the permeability of the economic space. The coefficient of curvature of the communication is calculated for the cities of the region. The question of potential labor migration from the regional centers to Saratov is also raised.
