The article deals with the submission of data on ecological and geochemical peculiarities of the forest ecosystems, still conserved, which were obtained during vegetation research of the Muravyov-Amursky Peninsula of the Primorsky Krai. For the first time, the species specificity on the heavy metal accumulations has been identified for many Far-Eastern species of the trees, bushes and woody climbing plants (78 species), which contribute to the formation of the natural phytocenoses of the South Primorye. The accumulative plant properties to accumulate heavy metals (Pb, Ni, Co, Cd, Zn, Cu, Mn, Fe) are found out in the different systematic groups and life forms of the plants. The best capacity to concentrate heavy metals (3-9 times more than background level) has been found in 14 species: Salix udensis and S. gracilistyla (Zn, Mn, Cd); Syringa wolfii (Zn, Mn); Lonicera caerulea (Co, Cd); Rubus sachalinensis (Pb, Cd); Populus tremula, Betula davurica and B. costata (Zn); B. platyphylla, Rhododendron mucronulatum, Aralia elata and Corylus mandshurica (Mn); Euonymus macroptera (Co), Alnus hirsuta (Cu). The best abilities for total metal accumulations have been observed at the families as Vitaceae (Pb, Co, Cd, Cu), Hydrangeaceae (Ni, Co, Cd), Rhamnaceae (Pb, Co, Cd) and Shisandraceae (Pb, Cu). All heavy metal contents, mentioned above, correspond to the local and backgroung levels at Sorbaria sorbifolia, minimum content – at Celastrus flagellaris liane. Coniferous species have low ability to accumulate most metals and also Juglans mandshurica, Fraxinus mandshurica, Tilia amurensis, Salix caprea, Ulmus pumila, Maackia amurensis, Berberis amurensis et al. The background contents of the most metals are registered in Acer mono, Abelia coreana, Crataegus maximowiczii, Phellodendron amurense, Ulmus japonica, Viburnum burejaeticum, V. sargentii. In the region of investigation the plant specificity and soils have been identified based on the ecological and geochemical criteria. The plant species that are perspective representatives for monitoring and photo indication in the regional environmental conditions, or close to them, have been proposed.
