forming the migratory currents connected with 
anthropogenic pollution and redistribution of the 
surficiai exhaust.All these data must be closely 
correlated with the information from hydrological 
control stations and other sources of ground observation. 
That is why the important significance should be 
given to the structure of elementary geochemical 
landscapes which does not only reflects the ways of 
migration currents but also shows the places of their 
functional concentration and localization of the 
ecological situations limits over the territory. The 
following must be analyzed: hydrological areas and 
zones ox harmful substances accumulation, also the 
areas and zones of their transportation, geochemical 
obstacles on the ways of migratory currents in the 
places of gravitational catching areas and terrain 
depressions(fogs , valleys and lakes bottoms). 
!hererore the mechanism of migratory currents of the 
underground and surface runoff, their interaction 
specifications in the geosystem structure must be 
specifically taken into the account. For example, an 
expremeiy diversified structure of genetic relief 
forms originated in the development conditions of the 
glaciar landscapes of the Europe and this determined 
composition, character and the availability of 
biospheric catching areas with ecologically 
protection features in them. 
The same picture can be seen in the river- 
valleys, in the areas of decline deposits development 
in combination with the field of alii vial formations 
development. Here arise and form the favourable 
conditions for water runoff and filtration of 
migratory particles in liquid and solid phases. In 
these conditions the depositation and deposits 
filtration areas with redistribution of the particles 
of organic substance and mineral solutions arise. A 
great importance for forming the conditions of 
subsequent stages of development of ecological 
situations has position in terrain and the character 
of content of fitting rocks. These features really 
are the main directional physical factors of the 
biota development and water condictuing features of 
the geosystem. 
In this connection it should be specially noted 
a description of the conditions for forming 
ecological situations in the depressions of relief. 
In the whole they are characterized by a specific 
migratory regime of substances which form geochemical 
background and special conditions of in— sight 
interactions of horisontal and vertical connections. 
This leads to accumulation of organic and mineral 
particles, their redistribution and sometimes to the 
transformation of the previous conditions. Towards 
here decrease migratory currents at a different speed
