Didoshak O. Ecology of shrub culturephytocenosises in urban ecosystem (on example of t. Lviv).

t. Lviv. The analysis of ecotopes conditions of shrub culturephytocenosises in urban ecosystem of Lviv, to define phytoindicative and phytomeliorative role of basic species of shrubs of various levels of pollution of an environment by heavy metals. Conventional anatomo-cytological techniques. Spectrometers C-115 and Percin Elmer, computer. It was determined the summary pollution indexes by heavy metals of edaphotops, their spatial peculiarity and piling up of heavy metals of shrubs phytomass. A phytoindicative and phytomeliorative shrubs role is characterized by coefficients of geochemical microedaphotope heterogeneity and biological absorption. For anatomo - cytological parametrs traces a difference of form and tendencies to changes of the shrubs in dependence on pollution level in urban ecosystem.
