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. 

The initial period (middle of XVI – late XVIII centuries) of the formation of the demographic and settlement on the territory of modern Saratov region. Territorial expansion of the young Russian centralized state in the Volga region started in the region the process of diffusion material-technical and social innovations, which structured the space, transforming it into the administrative system. Identified spatial and temporal trends, vectors of its development and the factors determining them.

The issues of connection of manufacturing industry of the region and the structure of its exports are considered. Features of export of some regions of the Middle and Lower Volga region during the last two years are analyzed. An assessment of the effectiveness of export activities is given. On the example of the Saratov region shows a change in the structure of exports for the period 2013-2017. The question of possibilities of import substitution in the Saratov region is raised.

This article considers the methodology for constructing a digital elevation model and its derivatives for analyzing the spatial distribution of linear erosion processes using the territory of the Khvalynsky district as an example. The authors propose the creation of a refined terrain model based on SRTM radar data, topographic maps and the interpretation of Earth remote sensing data. The creation technology is described and a comparative analysis of the refined model with the base SRTM is carried out.
