The article presents the agroclimatic characteristic of the winter season on daily meteorological weather data for 1941–2019 at the Saratov South-East (SE) station. The agroclimatic characteristic of the winter season at the stations of the Saratov region (Khvalynsk, Balashov, Ershov, Alexandrov Gai) is presented for the last 10 years. The point rating of the degree of favorable overwintering of winter crops was carried out at the Saratov SE station for 1962–2019.

The soil cover in the territory of the large recreational zone «Victory Park», which performs environmental, memorial and educational functions, was studied. According to the analysis results of mobile forms of heavy metals concentrations the assessment of the current sanitaryhygienic and ecologic-geochemical condition of soils was carried out. An excess of the maximum permissible concentrations in most of the samples for nickel, lead, and copper was found.

The issue of spatial planning includes the subject of taxonomy. It seems that it is necessary to switch to the practice of planning, in addition to the meso-level (subject of the Russian Federation), at two taxonomic levels: the macroregion and the economic microdistrict. To do this, the article identifies the main properties of these formations. On the example of the Volga-Ural macroregion the properties of integrity, complementarity and connectivity are analyzed.

The article provides an overview of the main types and features of cartographic support for the needs of tourists and tourist activities. An example of a modern thematic route is presented, as well as options for the compilation and layout of a tourist booklet. The research is aimed at popularizing regional tourism and attracting the attention of guests and residents of Saratov to non-traditional cultural and educational routes.

The development of the geosystems of the Russian Far East proceeds under the enormous but contradictory in nature double influence of the continent and the ocean and is carried out through the atmosphere. The goal is to characterize hazardous natural phenomena depending on the differentiated natural tension of the Far East (from maximum in the south to moderate in the north), often causing disasters and creating tense levels of the geoecological situation in general.

The article presents the results of work on the study of synoptic conditions for the formation of a dangerous weather phenomenon for the territory of Western Siberia – a thundersnow. The material for the study was the archive of aerosynoptic material from the Khanty-Mansiysk Air Meteorological Center.

Identifying the spatial structures of economic activity within a supra-regional entity is an urgent scientific task. In this study, it is solved using a combination of a framework approach and a model analog of the gravitational interaction for the cities of the Volga-Ural macroregion.

This article analyzes the current state of space-cartographic research methods and their application in strategic environmental assessment using the example of processing space-cartographic material and its digitalization in order to form a digital management platform that will further allow developing necessary measures for effective environmental management.

Volgograd, Samara and Saratov regions are neighboring regions. Demographic development in the regions has general trends. Migration is becoming the main component influencing the differences in population dynamics in the regions. The Samara region continues to attract both interregional Russian and international migrants.

Malignant neoplasms of the lymphatic system, which are characterized by damage to groups of lymph nodes and/or damage to internal organs are called lymphomas. The analysis of statistical data shows that there is incomplete information about the incidence in specific regions. The study of the prevalence of lymphomas, the need to monitor the incidence, and the identification and analysis of possible links between pathology and urban environmental features are an urgent problem.
