Abstract
Changes of vegetation properties (biogeochemical, morphological, floristic, phytocenotic) around Sibay chalcopyrite deposits were studied. Areas at different distances from mining facilities were investigated. Heavy metal (HM) content was measured in geographical components: soils, waters, bottom sediments, above-ground vegetation and several plant species ( Artemisia austriaca Salvia stepposa , Thymus marschallianus , Veronica incanа , Caraganа frutex , Phlomis tuberosa , Achilea setacea , Galium verum , Phragmites australis . Groups (pleiads) of species based on interspecific contingency coefficient were identified. The clusters represented ecological conditions and level of anthropogenic stress. The set of features for evaluation of transformation of natural territorial complexes by means of phytoindication was proposed.
