The ecological status of the technologically transformed and natural territories of Belarushas been ranked by changing the morphometric and cytogenetic indices of separate vegetative organs (lamina and root) in three model species of phytoindicators. Based on the results of multidimensional scaling (bootstrap (1000)), 3 clusters have been identified: the first combines the territories of large urban cenoses (Gomel+ Minsk), the second includes part of the republic territory most exposed to radiation pollution (Khoyniki + PSRER exclusion zone), and the third acts as a standard of the state of the environment (Berezinsky Biosphere Reserve). The suitability of plants of various taxonomic groups (Betula pendula Roth., Trifolium repens L., Allium cepa L.) as bioindicators for assessing the state of the natural environment has been shown.
