Biochemistry of the main trace elements of the Son-Kul hollow ecosystems
Steppe communities of the northern zone of the Son-Kul hollow are characterized by great species diversity. In ecological-biogeochemical and geobotanical aspects, dominant and species-rich formations and associations were described: Valesian fescue (Festuca valesiaca), desert oat (Helictotrichon desertorum), etc. Species diversity of vegetation cover of steppe and meadow-steppe northern zone of the Son-Kul hollow was studied. Microelement composition of soil and plants of steppe cenoses was determined. Dominants of steppe communities of the Son-Kul hollow in biogeochemical respect are high-growing and possess considerable microelement composition and stability to ecological factors. The species of fescue valesiaca (Festuca valesiaca), Tien-Shan wormwood (Artemisia tianschanica), which have high vitality to anthropogenic influences and geochemical factors were identified. They are proposed for introduction in highly weathered areas as erosion control plants.
