This article is devoted to problems of modern techniques of aesthetic landscapes objective appraisal. Such experience is shown according to example of Saratov. The base for an estimation are concepts «a morphological landscape» and «a morphological scenery».  

The more dangerous processes of modern geomorphogenesis of the territory of Saratov Volga region have been considered: linear erosion, plane wash-away, deflusion, landslide and reforming of Volgograd and Saratov coast reservoirs. 

The work presents the results of the elaborating of the regional system of long-range forecast of the weather character’s changing during a month, exactly on the days with sudden changes of average day-night air temperature and precipitation with the concretization of the falling date for the Saratov region. The sort of forecasting production and justification of the given way of the long-range forecast of weather elements’ development during a month are thoroughly shown. 

In the article change of the ethnic composition of the popularity of the Saratov region at the period from 1989 to 2002 are considering. The author shows as the role of the ethnic migration in given changes. In the region a number of people from the Caucasuc and Central Asia are growing. It is revealed, that: students are rather tolerant to emigrants; they are worried about the competition for job vacancy; conflict at the cultural ground is possible; they worried about demographical situation in the Russian Federation and its emigration policy. 

The concept of geoecological risk, its kinds is considered in article. The characteristic of natural-technogenic processes and display of factors of natural and technogenic risks is resulted. The opportunity of division into districts of territory of city on degree of display of risk is proved in article. 

The article is focused on the works of one of the most outstanding Russian geobotanics, A.N. Krasnov. A special attention is paid to one of his most interesting ideas concerning the so-called geographical combinations, which influenced dramatically the further development of the studies of geographical landscape and zone. The authors of the article analyze the main works of A.N. Krasnov devoted to the describing and characterization of landscape areas and zones, not only of Russia, but of the entire world.

The article is about the demographic situation of the Saratov region. The birthrate, the deathrate and the natural increase of the population of the districts, towns and the region in whole are considered, the causes conducive to its and the possible results are analyzed. There are many statistical data of the 1989, 1995, 1996, 1997, 1998, 2002, 2003 years. 

The concept of ground-information systems is opened and their structure is considered in article. Communication between geoinformation systems and ground-information systems is proved. Modern directions ground–information systems are resulted within the framework of geoinformation systems.

The power spectrum of time series of the incoming to the Earth irradiance flux of the Sun under the assumption of the invariability of its luminosity in the time interval from 1700 through 2000 is analyzed in the region of frequencies, connected with the motion of the Moon. In the power spectrum of insolation, together with the basic peak with the period of synodic month 29d .53, are manifested also the peaks corresponding to the combination frequencies of this month with the harmonics of the annual period of the Earth.

Based on multi-year data about the changes in the ground water level a statistical criterion for the variability of ground water natural circulation mode in the urban lands in offered in this article. It is expedient to use the suggested value of environmental disturbance for making an inundation map of level environmental disturbance when simulating the land potential ground water inundation (waterlog).
