Research techniques: landscape indication, the physicochemical methods: atomic-emissive spectral and roentgen-phase the analysis. Distribution of technogenic units in the system snow-soil-plant bases on monitoring of states of natural complexes: valley and water-separate. Snow contains a small amount of heavy metals, but plays the important role in migration of contaminants as melt-waters are medium for fast migration polutants. In the spring melt-waters wash off a part of heavy metals from a "boosted" phases valley and water-separate visual environments in "reduced". In the spring it gives in high concentration almost all researched metals in the "reduced" phases. During a vegetation period of a plant of an experimental phases store in itself heavy metals which contents in soils because of it decreases. The researched cultural sorts of plants are characterized by the fissile accumulation of heavy metals young sprouts in autumn and spring periods of a season of vegetation and essential decrease of their absorption in the summer. Link of existential legitimates of allocation of technogenic units in natural ingredients of visual environments with their chemical properties and geomorphologic features is specific. Intensity of arrival polutants in plants of different visual environments tends to their delimitation on groups depending on space and time.
