The article represents work periods succession of projecting and making of Saratov region educational- local history electronic atlas. Also some aspects of atlas making methodology are disclosed.
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.
Article is about the possibilities and features of application of test technologies in teaching the World Economy Geography. The author believes that test technologies are an integral part of the control of mastering of knowledge in teaching the World Economy Geography, motivations of informative activity of students, and also serve a feedback establishment between the teacher and the student. On the basis of a private experience in article recommendations about drawing up of tests are made.
The studies of the demographic structure of the population, the characteristics of migration, the intraregional differences in the demographic situation, consideration of socio-economic ranking of the region give the grounds to draw a conclusion about the inevitability of the further process of depopulation in the region, the deterioration of the «quality» of the population.
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.
In article the specialised geoinformation system created by the author «GIS-national park “Hvalynsky”» is considered. Conceptual bases of the GIS, the maintenance of separate modular blocks, thematic structure of databases are shown.
In article results of the comparative analysis of topology valleys complexes within the modeling range located on east macro-slope of the Privolzhsky height are shown. Comparison of the urbanized and not urbanized territories has allowed to reveal landscape analogs city valleys. The received results give the grounds for interpolation of geodynamic parameters of an erosive network with a view of development of practical recommendations about ecological optimization city planning decisions.
The first, rather large protected areas in Germany were created in 19th century under the influence of romanticism, requirements to national definition and proceeding from a socioeconomic situation. It occurred before national parks in USA were created and the German nature protection program formed. The article presents those of them which as much as possible resemble modern nature parks in their problems and organization. The history of their development as protected areas is characteristic for Germany thanks to private, public and state initiatives.
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.
Statistical analysis of the most popular and often used laws of distribution, that used for probability estimation of various wind speed: Puasson, normal, longnormal and Viebulla-Gudrich laws with application of Pirson and Kolmogorov criteria was carried out. This law is recommended to use for wind conditions mathematical description for on the south-west of european part of Russian Federation.
Different methods of characteristic Viebulla-Gudrich distribution estimation for wind speed leveling on the south-west of European part of Russian Federation are considered. For this purpose is recommended to use moments methods and least-squares method, that minimized the volume of calculating works. Distribution characteristics estimated by these methods allow identifying wind speed conditions, mean values and measures of variability on the south-west of European part of Russian Federation.
The article represents results of scientific-innovation educational centre of geoinformational technologies (GIS-centre) activity. Also briefly reports projects realized by GIS-centre concerning of GIS methodology implementation to Povolzhie’ scientific-production and production organizations and lay down general working trends of the Saratov State University new innovation organization – the interregional centre of space monitoring.
The article presents the results of laboratory investigation of water samples collected in the summer of 2016 on the rivers of the Soviet district of the Saratov region. A brief analysis of the hydrochemical indicators is given from the point of view of their effect on the water quality of the examined rivers. Based on the results of the analysis, the relevant conclusions were drawn. At some points of sampling, exceeding the values of maximum permissible concentrations for a number of indicators was detected.
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 results indicate the cyclic nature of the process of change consists of several stages.
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.
The influence of certain meteorological conditions on the conditions and speed of the eolian processes on the Curonian Spit (the southeastern part of the Baltic Sea) is considered. It is shown that the wind conditions are the most influential, especially in the autumn-winter period. The limiting factor is the amount of precipitation. Temperature conditions and relative humidity are not an obstacle for the processes under consideration.
The article presents the results of the geo-ecological state analysis of steppe landscapes of oil and gas fields within the Volga-Ural oil and gas province. As a key parcel were selected polygons with an area of around 100 sq. km each. The digitization of key sites of oil and gas objects location and road transport network has been executed. It has been shown that the most large-scale and widespread changes are disturbances of soil and vegetation cover, which occur as a result of the introduction and operation of the area and linear infrastructure of fields.
Based on the analysis of satellite images and field survey of the site «Burtinskaya Steppe» of the Orenburgsky reserve, it was revealed that steppe fires are one of the most significant limiting factors in the development of woody and shrubby elements of steppe ecosystems. A high restorative capacity of forest tracts is noticed, especially in the conditions of increased soil moistening.
This article deals with the problem of economic zoning associated with the methodology of allocation of economic microzones, proposed by E. E. Leyzerovich. A comparison of meshes of the zoning of different years is carried out, the reasons of their differences are established. Possible changes of types of economic districts of the Volga region and the factors promoting them are considered. Comparative development of industry in the districts is analyzed.
In the article on daily meteorological data for the seventy-year period (1941–2011), the agroclimatic characterisation of the seasons of the year in the Saratov region are given. The structure, duration and weather conditions of each season are considered.
