Abstract
As new ecological and geochemical indicators of ecosystems state it is proposed to use the indicators of absolute (IAA) and relative (IRA) accumulation of chemical elements in certain geochemical systems. The example of forest landscapes of the Western Caucasus shows the change of these indicators during the transition to landscapes of orchards, rain-fed fields, rice checks. In the soils of the considered anthropogenic systems various elements affecting the chemical composition of agricultural products are accumulated and removed from them.
