Theoretic basis of all-purposes climatic-information technology estimation of potential and utilize wind-energetic resources and windenergetic plant service conditions are developed. Acceptable error of wind-energetic characteristics spatial renewal, wide range of facilities, usability and other qualities of this technology are conclusive proof for its application in stage of preproject development

The article shows results of snow-geochemical survey in Saratov city territory in 1992, 1994, 1997 and at the beginning of 2000th, that was made by the staff of geographical and geological faculties of Saratov State University. The research revealed essential area decrease of snow cover pollution of industrial emission at the beginning of 2000th   as compared with 1990th. Abrupt snow pollution increase along the transport mains and around the large working enterprises

At echelons of airplane lying in the upper troposphere and low stratosphere, air temperature varies sharply, which affects the speed of airplane, fuel consumption and height of the airplane ceiling. The paper presents calculations of these characteristics of the aircraft depending on the temperature on the routes crossing of cyclones and anticyclones

In article experience of the gumanitarian geographical researches spent during projects on cultural designing of territories of local and regional scale is shined. The original technique of field studying of the historical environment is resulted, application of GIS-technologies in modeling of a cultural-symbolical landscape is considered

The construction and operation of industrial objects of oil and gas branch cause negative influence on environment. It could be minimized under condition of a well-organized system of ecological monitoring and acceptances of corresponding preventive works. In a view of optimization and also for increase of efficiency of ecological monitoring there are necessary the well-founded choice of points of prospective works.

In the article we have analyzed resettlement of the rural population, the changes that had occurred in population size in the settlements in question, peculiarity of migration, and the demographic diversity within different regions. Based on the analysis the conclusion can be drown that the system of the rural settlements is a subject of great change. According to the upcoming change the population will be concentrated in big settlements and along the thoroughfares. Rural conglomeration will face a considerable development.

The article represents the integration processes, that caused by the unification of Germany and that continues to present days. It is established that the restructuring and privatization have contributed to the restoration and further growth of the chemical industry in new federal lands. Also the contingence of the integration process with a change in the territorial structure of the chemical industry in East Germany and their influence to the creation of the networks (clusters) is indicated in the article

The article represents risk modeling of emergency situation during accident of model part of Petrovskiy district (Saratov region) gas main with GIS technologies using. Also methods of detonation zones estimation and cloud of dangerously explosive blend spreading estimation during accident gas main depressurization subject to wind direction and speed are represented

Connection is established and the mathematical expressions are received, allowing to estimate parameters of sedate and logarithmic functions of height on value of average speed of a wind at level of 10 m on SOUTH-EAST ЕUROPEAN part of Russia

This article touches upon daily urgent factfiles during the 30-year period. The author of the article calculates all famous in literature criteria of drought. But no one of them reflects a degree of a strong drought when more than 70% of crop dies. The author introduces first the physiological coefficient of drought
