Критерии за оценяване химичната нееднородност на биосферата

Abstract

In the end of the 19th century Klarck proves that lithosphere in chemically heterogeneous. In 1934 Fersman proposes a quantitative criterion for assessing this heterogeneity - the Klarck (K) unit. In the 20th century Vernadsky determines the chemical heterogeneity in the biotic components of biosphere. Research is mainly carried out about determining the concentration or dispersion of chemical elements in autotrophs, due to the fact that they compose 90% of living matter. In this research we set our aim to propose new criterions for the assessment of chemical heterogeneity of biosphere by making a complex evaluation of the characteristics of movement of matter.
