Authors: Tarkhova L. A., Berlin N. G., Kadykova Y. S.

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

Some Results of Data Processing of Absorbed Solar Radiation and Albedo from Radiometer IKOR-M

Authors: Sklyarov Y. A., Chervyakov M. Y., Vorobyov V. A., Kotuma A. I., Feigin V. M.

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

 

Growing Conditions of Winter Crops in Autumn and Their Status to the Time Discontinued Vegetation in Saratov Region

Authors: Pryakhina S. I., Guzhova E. I.

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

Droughts and Evaluation their Criteria

Authors: Pryakhina S. I., Guzhova E. I., Zlobin R. I., Kuznetsova S. A., Smirnova M. M.

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.

The article represents main features of modern interactive educational technologies adoption of higher school educational process (with geoinformation systems classes as an example)

Landscape Zoning of the Saratov Region’ Right Bank

Authors: Makarov V. Z., Pichugina N. V.

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

Estimation of the Present State of Agro-climatic Resources of Saratov Region

Authors: Ivanova G. F., Levitskaya N. G., Orlova I. A.

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

Search for Long-period Harmonics of Insolation Changes Caused by Planetary Perturbations of Earth’s Orbit

Authors: Bogdanov M. B.

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.
