Coming to the Earth a flux of solar radiation is calculated using of modern numerical methods of celestial mechanics over a time interval of about 6000 years with the sampling interval of one year. The luminosity of the Sun was assumed constant. In the power spectrum of the insolation time series detected harmonic of the synodic period of the Mars, as well as harmonics of the combination frequencies of synodic periods of the planets Venus, Jupiter and Saturn, and the frequency corresponding to the sidereal year.
The paper demonstrates the modern agro-climatic recourses for the period 1981–2012 years and their comparison with the climatic norms for the last period 1912–1980 gg. Shows trends multiyear variations of agro-climatic indices by natural zones of the Saratov region
The article is devoted questions of regional level geosystems landscape zoning with Saratov region’s right bank as an example. Mapping was organized with GIS technologies using on the basis of topographic and thematic maps and space images decoding
The article represents main features of modern interactive educational technologies adoption of higher school educational process (with geoinformation systems classes as an example)
In this article, on the basis of daily meteorological material over the thirty years period the drought criteria are according to Selyaninov, Shashko, and Kabanov’s works. The most productive indicators are selected; best rate the degree of the aridity over the particular period. The criteria are considered in the drought insurance and subsidy payments to agricultural producers in the lean years on the regional and state level. The analyzed coefficients do not fully show the rate of drought, i.e.
On daily weather data for the 30-year period (1981–2011 years) st. Saratov South-East considered agrometeorological growing conditions of winter crops. The optimum sowing date and the temperature crosses 10оC, 5оC and 0оC. Analysis of the data showed that global warming shifted the date of transition temperature to a later date, which is important for growing crops. According to favorable autumn growing season were given numerical score of the fall season
The description of some results of three years of radiometer IKOR-M working is given. The possibility of comparisons of IKOR-M data with CERES data, working on three satellites is reviewed. The results of the calculations in the tables’ form of the absorbed solar radiation (ASR) for areas of equal size are presented. The temporary peculiarities of ASR in the Mediterranean area are considered. The mean monthly values of albedo over the Sahara, the Amazon Basin and tropical Africa are evaluated
In article stages of the organization of the ecological track laid on the territories of natural park «Kumysnaya Polyana» of the city of Saratov in detail reveal, the route with elements of improvement and information registration is offered, the assessment of an ecological condition of the geosystems adjoining a track is made
The paper presents the study materials vegetation using GIS and remote sensing data – satellite images. The description of this method of processing satellite images as «Tasseled cap», describes its advantages as compared to untreated so satellite images of vegetation in the study region
The changes in Saratov region ethnic composition during 2002–2010 are reviewed in the article. Also reviewed is demic diffusion throughout Saratov region districts and towns. The role of ethnic processes and ethnic migration in population change and its geography is elicited. The growth of people from Caucasus and Central Asia is noted
Article is devoted theoretical and methodological aspects of the functional organization of a cultural landscape. An object of research is ecological function which acts as external display of properties of landscape components in inter-element communications of nature-social systems. As a technological platform the cybernetic landscape – interactive operated computer model is considered
The article shows characteristic of regional features of oilfield’s geoecological risk (with Saratov region as an example). Geoinformation systems (GIS) and mathematical and cartographical models as a tool of their analysis are disclosed possibilities of using
In this article some existing sustainable development indexes and indicators are considered. Sustainable development rates territorial differentiation on municipal level is offered. Territorial planning schemes are proposed as a basis for municipal districts sustainable development indexes creation.
On the basis of a long series of observations (1912–2010 gg.) investigated long-term variability in temperature, precipitation and other meteorological parameters. It is shown that climate normal of temperature and precipitation in the modern period is significantly different from the baseline period of 1961–1990 gg., proposed by the WMO
In this article the methodology integrated geo-environmental study of the national park landscape-based morphological approach. On the example of the National Park Hvalynski the results of studies using morphological landscape conceptual model
The article represents possibilities of GIS technology in addressing the problem of optimizing route of gas main in the Petrovskiy district of the Saratov region. Also classical method of calculating the optimal search area of gas main and major factors that influence the position of the route are represented
On the basis of a new approach to the study of the circulation of objects in the hemisphere physical-statistical method considered changing dynamics of the main circulation system of the Northern Hemisphere. Based on this approach, the peculiarities of the circulation regime change in the hemisphere at different periods of the Earth’s climate system
In this article it is shown that on the background of the second wave of the global warming on the territory of Saratov and the region is well noticeable climate change, especially in the multiyear averages, mean monthly temperatures, as well as the duration of the main and the transitional seasons of the year. Noted the contribution of the circulation in the formation of the climatic characteristics of the region
There is a history of the term ≪nature monument≫ in the German science and nature conservation practice between the end of XVIII century and 1920th in the article.
