Abstract

The methodological substantiation of the ecological and geochemical assessment of the urban arboriflora species composition is given. The urban populations of the 81 trees and shrubs species forming the Vladivostok green spaces are compared in terms of their ability to optimize the urban environment. The priority pollutants of urban vegetation have been identified – Fe, Zn, Pb, Cu, Ni. The species of high, medium (background) and weak accumulation of heavy metals have been established. The plants-metal concentrators have been identified: Crataegus pinnatifida (Fe), Sorbus pochuashanensis and Picea sp. (Mn), Populus maximowiczii and P. nigra (Zn). The recommendations for the differentiated and rational using the species in urban landscaping structure are given.
