The main and typical changes in the natural complexes of tundra and forest-tundra in the areas of development of oil and gas fields were considered. Assessment of the stages of transformation of plant communities and soil cover due to anthropogenic load has been characterized. With the development of gas and oil fields in the north, pollution leads to a significant transformation and degradation of natural complexes. However, these violations are insignificant in area and localized. Various mechanical disturbances...

Construction development of forest-tundra areas shall take into account their peculiar characteristics: enhanced susceptibility of landscape components to man-made impact, presence of permafrost, and also insufficient exploration of environmental conditions. These factors make it essential to carry out a detailed investigation of natural and man-made conditions as a part of engineering and environmental surveys during environmental feasibility study of the projected construction in such areas. This work is dedicat...
