Ecological and Geochemical Characteristics of the Landscapes of Western Tuva.

摘要

ABSTRACT We have performed ecological and geochemical evaluation of the landscapes of the Khemchik depression (western Tuva). We have calculated values of total soil pollution with heavy metals, as well as the coefficient of biogeochemical transformations indicating changes in microelement composition of vegetation. We have found that the investigated area slightly contaminated in ecological and geochemical terms. Mapping of ecological and geochemical environment has demonstrated the difference.
