The article presents data on the development of approaches to the reconstruction of the paleo-environment of the habitat of the Lugovo culture by means of the conjugate analysis of the soil-archeological and geochemical parameters of the soils of settlements and buried soils of the burial mounds. As a working hypothesis, it was suggested that meadow-steppe conditions for the formation of geosystems of the period of development of the Lugovsk cultural-historical community, dating back to the 15th–14th centuries. BC.

The spatial aspects of the formation of cultural space of the city according to the scheme «point-line-area» were examined. The main cultural line of Saratov was considered, some potential lines were revealed. The principles of formation of cultural space of the city were proposed. The role of citizens in maintaining a cultural space was examined.

The article considers the causes and factors of the unfavorable atmosphere-ecological situation in Saratov. Particular attention is paid to factors of a natural and socio-economic nature, creating an increasingly unfavorable trend in the development of the atmosphere-chemical situation in the city.

The article presents the results of studies of deflationary and accumulative processes in the south-east of the Tomsk oblast’ for the past 30 years. The authors identified natural and anthropogenic factors, two stages of development of eolian processes in cold period of year. It has been established that eolian processes develop annually in agrolandscapes of Basandaika river basin but with varying degrees of intensity.

The construction of the Volga-Kama cascade of reservoirs in the middle of the 20th century.led to the development of abrasion processes and the disappearance of monuments of archaeological and cultural heritage. So, on the surface of the second terrace above the floodplain p. Kama near the place of its confluence with the river Utka, studied

The landscapes of polar countries are neither young nor secondary. An external shape and internal composition of polar landscapes are created as a whole by permafrost (continuous, faltering with taliks and island). In some cases, under unfavorable conditions, its own destructive influences on landscapes are strengthened by endodynamic risks (first of all, by seismicity flashes from 1 to 2 points).

The article provides an algorithm for constructing of hydrologically correct digital terrain model. The main thematic terms and definitions are given. The construction of watercourse network on the territory of Saratov region and construction of watershed basins has been carried out by GIS-technologies. An algorithm for constructing flood zones of the territory has been developed to identify the most vulnerable objects.

With the use of modern numerical methods of celestial mechanics, the incoming irradiance flux to the Earth from the Sun has been calculated under the assumption of the invariability of its luminosity through interval of 1700–2000 A.D. Harmonics of the annual period of the Earth as well as harmonics of the synodic period of Venus, Mars, Jupiter, Saturn and harmonics corresponded to combination frequencies, are clearly visible in the power spectrum of time series of the insolation. The periods of these harmonics are located in the range from 100 days to 15.7 years.

Long-term variability of some meteorological parameters in the Saratov region is analyzed in this paper. For the period of observation from 1930 to 2004 at six stations in the Saratov region, linear trends of average, maximal and minimal air temperatures, the sum of atmospheric precipitations for various months and seasons have been gained. These results suggest reduction of continentality of a climate in the region. 

In the present article the authors give substantiation of agroclimatic resources and description of such unique climatic phenomena as zoning and seasonality. Monitoring of meteorological elements for the period of 50-70 years forms the essence of characteristics of Saratov region climate, average temperature characteristics have been calculated for the period of more than 100 years.
