Saratov Region

The article presents the experience of overcoming of one of the most domestic internal educational risk – the risk of the number of entrants incompetence. Considered the possibility of GIS technologies introducing in the analysis of spatial distribution, quantity and quality of potential applicants with inspection board of geography faculty of Saratov State University as an example.

In the period 2010–2015 the various sectors of economy of the Saratov region showed multidirectional movement. This is especially true for crops and livestock. The article analyzes the spatial shifts in production of certain products of industry with the use of Herfindahl–Hirschman index.

The key points of the Strategy for socio-economic development of the Saratov region till 2030 against primarily the spatial organization of а manufacturing industry are discussed. The proposed typology of districts is annalysed.

?In the article results of research concerning ability of atmosphere in self-purification in Saratov and the Saratov region are presented. Dynamics of the atmospheric self-purification coefficient in various areas of the Saratov region is analysed during warm and cold seasons for the long-term period and from 2000 to 2004. The formula of the atmospheric self-purification coefficient’s calculation is improved according to regional climate conditions. Maps of spatial differences in atmospheric ability for self-purification on the territory of Saratov are constructed.

The regionalization of Saratov region commercial oil production region supporting with GIS is made possible to mark out (within the research region) several areas with different resistance to oil pollution subject to area types and native zones. 

The article considers climatic and soil factors, that limit adoption of plant-breeding within the north semidesert. Analysis of long-term observations data in Aleksandrov Guy weather station, thematic maps (soil and landscape maps), space images and field research materials were made for this work. As the result of performed work, authors made the list of agricultural crops that could be recommended for cultivation in semi-arid term of Saratov Zavolzhie. 

This article is devoted to the analyses of the role of tree-shrubbery vegetation of natural and anthropogene origin in the structure and functioning of landscapes of semi-desert Saratov Priuzenye. In this work there are used the materials of field field researches of different years, topographic and subject charts, space photographs, elements of GIS-technologies. 

The article represents general concept of the «risk» and concept of geoecological risk as a one of oil-fields’ risk exploitation manifestation within the regional features of Saratov region. Also the general chart of risk estimation with emphasis on cartographical risk-analysis of oilfields with application of GIS is disclosed in the article. 

The article is devoted to mapping questions of local semi-desert Saratov Priuzenye geosystems and facilities of cartographical works using for landscape structure identification and it’s variation as a result of anthropogenic load on the territory. Different ages field research, topographical and thematical maps, space images, geoinformation technology’ elements are used in the work. 

During long-term operation of oil and gas fields in the groundwater on their territory are formed hydrogeochemical anomalies expressed primarily chlorellaman type chemical composition, typical of the zone of active water exchange. The formation of the chemical composition of groundwater is influenced by many factors, both natural and manmade.
