    This work contains a monitoring 4 spring ecosystems varying degrees of anthropogenic impact, as indicators of the quality of the environment by vegetation appraisal and analysis of the content of heavy metals in it. It is istablished the relationship between the state of natural plant communities, changes in the properties of the soil, the quality of spring water and the level of anthropogenic impact on these ecosystems. It is offered promising plant accumulators of heavy metalsΠŸΡ€Π΅Π΄ΡΡ‚Π°Π²Π»Π΅Π½ ΠΌΠΎΠ½ΠΈΡ‚ΠΎΡ€ΠΈΠ½Π³ 4-Ρ… Ρ€ΠΎΠ΄Π½ΠΈΠΊΠΎΠ²Ρ‹Ρ… экосистСм с Ρ€Π°Π·Π»ΠΈΡ‡Π½ΠΎΠΉ ΡΡ‚Π΅ΠΏΠ΅Π½ΡŒΡŽ Ρ‚Π΅Ρ…Π½ΠΎΠ³Π΅Π½Π½ΠΎΠ³ΠΎ воздСйствия, ΠΊΠ°ΠΊ ΠΈΠ½Π΄ΠΈΠΊΠ°Ρ‚ΠΎΡ€ΠΎΠ² качСства состояния ΠΎΠΊΡ€ΡƒΠΆΠ°ΡŽΡ‰Π΅ΠΉ срСды посрСдством Π±ΠΎΠ½ΠΈΡ‚ΠΈΡ€ΠΎΠ²ΠΊΠΈ Ρ€Π°ΡΡ‚ΠΈΡ‚Π΅Π»ΡŒΠ½ΠΎΡΡ‚ΠΈ ΠΈ Π°Π½Π°Π»ΠΈΠ·Π° содСрТания Π² Π½Π΅ΠΉ тяТСлых ΠΌΠ΅Ρ‚Π°Π»Π»ΠΎΠ².

    Succinic acid influence on migration properties of lead and cadmium in soil-plant system has been investigated. It has been shown that the addition the activator (succinic acid) into soil increases the efficiency of phytoextraction of lead and cadmium.

    The approach of estimation of a level of anthropogenic impact on ecosystems as a function of properties of plant associations has been proposed. In the course of investigation it was established that it is possible to estimate the growth degree of anthropogenic impact on ecosystem by: the increase part of a ruderal vegetation in common composition of plant associations; the increase amount of a ruderal vegetation growing on one square meter of soil surface (thickness of sowing); the increase of lead and cadmium content in above ground part of the plants. The sufficiently high ability of lead extraction from soil by such plants-accumulators as great nettle and meadow fescue has been establishedΠŸΡ€Π΅Π»ΠΎΠΆΠ΅Π½ ΠΏΠΎΠ΄Ρ…ΠΎΠ΄ ΠΊ ΠΎΡ†Π΅Π½ΠΊΠ΅ уровня Π°Π½Ρ‚Ρ€ΠΎΠΏΠΎΠ³Π΅Π½Π½ΠΎΠ³ΠΎ воздСйствия Π½Π° экосистСмы Π² качСствС Ρ„ΡƒΠ½ΠΊΡ†ΠΈΠΈ свойств Ρ€Π°ΡΡ‚ΠΈΡ‚Π΅Π»ΡŒΠ½Ρ‹Ρ… сообщСств.
