Model of the Geoecological Assessment of a Territory

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. 

Conditions of аutumn Vegetation and Wintering of Winter Crops in Saratov Region

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. 

Regionalization of Saratov Region commercial Oil Production Region according the Territory resistance of Oil Pollution with GIS Supporting

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. 

Structure and Dynamics of Saratov City Geochemical Fields

This article represents structure and dynamics of anthropogenic geochemical anomalies halos within Saratov city territory as a result of the last 15th years research. 

Concerning the Peculiarities in Determination of Daily Averaged Albedo in High Latitudes

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. 

Albedo, Absorbed Solar Radiation and Outgoing Longwave Radiation Derived from Data of NASA Atlases

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.

Geomodeling of River Basin Based of the Space Data SRTM (as Example of Tereshka River)

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.

Fire situation Modeling within Oil-Gathering Stations Using Geoinformation Technologies

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. 

Unique Steppe Natural Complexes of the Left Bank Volga River in Saratov Region

According to field researches of the Left bank Volga river in Saratov region in article are shortly presented descriptions of two steppe sites which are unique for this strongly agriculturally transformed territory. The inference are made about necessity of special researches around there, because it is the most perspective for search steppe protected areas. 

Possibility of Buing of Food-Stuffs in Regions of Privolzskiy Federal Areal

Possibility of buing of food-stuffs in Regions of Privolzskiy Federal Areal. The position of Saratov region among the other areas of Privolshsky region concerning the food consumption is shown in the article. This position is the most important index of food safety level. In the article the salary is represented as en element buing of food-stuffs and buyer ability.
