ABOUT CHEMICAL COMPOSITION OF LYZIMETRIC WATERS IN HIGH MOUNTAIN ECOSYSTEMS
The article contains a study of chemical composition of lyzimetric waters of alpine and meadow steppe belts of the Aragatsi mountain massif and is focused on macro-element and heavy metal migration in system soil-lyzimetric waters including their inflow with atmospheric precipitation. The research allowed detecting high contents of macro-components in the studied compartments of meadow steppe belt. As indicated, chemical elements migrate more intensively in meadow steppe vs. alpine belt. With increasing absolute altitudes (alpine belt) soluble organic matter in composition of lyzimetric waters increases rather than decreases, whereas lyzimetric soil solutions in the noted zone vs. meadow steppe soil are more acid and less mineralized.
