This article is represented cartographical-mathematical models of oil-gathering stations’ fire risk factors for population and surrounding area. Based on geomodeling are created models of oil outflow, explosive concentration in the time of oil evaporation, models of overpressure risk areas’ radius, thermal radiation risk area modeling in time of oil fire.
This article is devoted to questions of digital modeling of river basin area. The basin of the Tereshka River appears as the research object. The author results detailed algorithm of river basin geomodeling by using of computer software (ArcGIS, ESRI) on the basis of the space data (SRTM). Characterizing relief and water flow models are created. As a result watersheds and stream network are delineated.
The results of investigation of main Earth radiation budget (ERB) components derived from the measurement on the Nimbus-6 and Nimbus-7 satellites and published in four NASA atlases are given. The data of latitudinal albedo distribution are described. The methodic for receiving of global and hemisphere values of albedo is proposed. It is showed that global averaged albedo values from Nimbus-6 satellite are less than from Nimbus-7 at 5 albedo units (0,28 and 0,33 correspondingly). The annual variations of global and hemispherical albedo values are discussed.
The paper is continuation of a work, published earlier and gives the details of the method of determination of daily averaged albedo values in high and nearpolar latitudes. The examples of calculations are given.
This article represents structure and dynamics of anthropogenic geochemical anomalies halos within Saratov city territory as a result of the last 15th years research.
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 analysis of meteorological data obtained daily for 67 years was made to select the criteria for evaluation of hardiness and wintering of winter crops. The highest repetition frequency of disadvantageous winters was observed in 1960-s. The increase of temperature and precipitation during the winter in the past thirty years has created advantageous conditions for cultivation of winter crops in Saratov Region.
In this article the method of creation a cartographic model of the geoecological situation of a territory is considered. The description of maps creation and their purpose is given. The necessity of relief using as the object of mapping in the creating a geoecological map is justified.
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.
In article on the basis of field researches August, 2009. The problem of pollution by manganese of waters of the Bolshoy Irgiz river in the Saratov and Samara areas, and also on a water fence of Pugachev is considered. Results of chemical-analytical works about quality of river water in a channel, flood-plain lakes, ponds and water basins of Bolshoy Irgiza, and also on a city water fence and water supply systems are resulted.
Society development is closely related to collecting of geographicallydistributed information, where the main accumulation and storage role plays atlases, and electronic atlases. 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.
