THE ACCUMULATION OF TRACE ELEMENTS IN THE ABOVEGROUND MASS OF PLANT LIFE FORMS IN THE GEOSYSTEMS OF THE ONON-ARGUN STEPPE

The paper presents the results of analysis performed to reveal chemical features life forms aboveground mass plant species predominating in geosystems Onon-Argun steppe on Kharanor transect testing area. On basis biogeochemical studies plants, possibility analyzing patterns geosystems’ functioning has been revealed. choice area was determined by landscape structure, forming a landscape-ecological series where facies are connected with each other. Facies as whole characterized low-mountain relief and sharply continental climate change. To assess study area, atmospheric precipitation air temperature were analyzed (data from Borzya weather station). Trace elements ash studied at licensed chemical-analytical center V.B. Sochava Institute Geography SB RAS. Each is well-defined content green part well organs individual forms. dynamics accumulation distribution trace dominant traced. Their changes significantly during growing season. In spring, active growth increases, their maximum falls tillering maturation phases. weakens earing flowering phase increases again end
