In the study, based on the analysis of literary sources and the own research materials, the characteristic of the environmental situation in Taimyr is done, in connection with aerial technogenic impact of the Norilsk mining and metallurgical industrial complex. The dynamics of forest condition over the past decade in the area close to 200 kilometers or more from the plant were evaluated. The analysis was performed taking into account the landscape structure of the territory. The progressive drying of the large areas of the northern forests since the early 80 is registered. In the article, according to the literature reviewed, the structure, dynamics and distribution of air industrial emissions of the Norilsk mining and metallurgical industrial complex «Norilsk Nickel» is analyzed and presented. Further, the authors considered the impact of air industrial emissions of Norilsk industrial region on the forest ecosystems of Taimyr. The focus is on the main forest-forming tree – Siberian larch Larix sibirica Ledeb. It is noted the complete absence of the larch undergrowth in the area of ​​industrial pollution. Investigation of the technogenically damaged forests was carried out on the basis of dendrochronological research at six different points on different distances from the city of Norilsk, mainly to the south and east of the metallurgical plant. One study point (sparse larch community) is located 5 km north-west of Norilsk. We investigated stands of varying degrees of damage, including completely dead. It is shown, that outside the area of Norilsk mining and metallurgical industrial complex impact ​​there were no signs of damage to the foliage of the trees and on the contrary, in the area of ​​air pollution (Khantaiskoe Lake), forest stands are largely affected. The main damaging agent is sulfur dioxide.
