Abstract
The analysis of topoecological differentiation of vegetation in the Norilsk industrial region, reflecting the response of plant communities on the technogenic impact, was conducted. The basic directions of phytocenotic successions, involving replacement of forest associations by tundra and meadow-marsh complexes, were detected. It was noted that upland areas, depending on their orographic confinement and distance from the source of technogenic emissions, were dominated by mono- and oligodominant herbaceous and shrubby plant communities, which had replaced moss-lichen and shrub associations. The highest level of biodiversity and productivity was shown by meso- and hygromorphic ecosystems on low terraces which were considered to be regional cenotic refugiums.
