The paper presents the results of comprehensive studies on the problem of formation of a deposit of heavy metals in plant communities of the West Siberian Arctic and Subarctic. The regularities of the concentration and redistribution of heavy metals in the soil-plant system have been revealed. Excessive accumulation of heavy metals by different plant species is limited by the selectivity of root absorption in relation to certain elements, and therefore it is important to calculate the coefficient of biological absorption. The interrelation between the intensity of recreational loading and change in the nature, grass cover structure.Among the identified pollutants that accumulate by plants identified a group of heavy metals and microelements (Pb, Sr, Cu, Zn, Ni ). It is shown that the linear dependence of the accumulation of metals in the system “soil-plant” is observed only in the range of low concentrations of pollutants in the ground growing. With high concentrations the reverse dependence occurs. Formulated, justified and tested methodical approaches to preparation of complex long-time observations of the natural ecosystems.
