Abstract
The article reflects the results of anthropogenic impact on phytocenoses of the territory of the Uporovsky regional nature reserve (Uporovsky district, Tyumen region, Russia). On the territory of the Uporovsky regional nature reserve (Uporovsky district, Tyumen region) there is a 110 kV electrical power transmission line (power line) which has the length of 8 kilometers and the right-of-way width of about 30 meters. This power line is undoubtedly the main source of anthropogenic electromagnetic radiation in this area. The degree of participation of individual species in the herbage was determined by taking into account their relative abundance. When exposed to the power lines in the right-of-way area, flora biodiversity decreases due to the loss of a number of species. The effect of electromagnetic fields causes transformation of the vegetation cover, synanthropization and the subsequent complete destruction of natural vegetation. To determine the degree of anthropogenic load on the studied phytocenoses, the synanthropization index is determined. In the synanthropic fraction of the flora, 30 species belonging to 12 families were identified. The synanthropization index of the studied phytocenoses ranges from 6.6% to 81.2%. The largest number of synanthropic species is observed in the anthropogenic area.
Highlights
At present, the anthropogenic impact on the environment is steadily growing
One can single out the effect of electromagnetic fields (EMF) generated by power lines affecting animals and plant organisms that permanently or temporarily inhabit areas where they are exposed to these fields [1,2]

Summary
The installation of high voltage power lines poses a number of environmental, social and economic problems. One can single out the effect of electromagnetic fields (EMF) generated by power lines affecting animals and plant organisms that permanently or temporarily inhabit areas where they are exposed to these fields [1,2]. Despite the fact that power lines have become an almost mandatory component of landscapes of populated areas, not so many information about direct observations or field work in the area of EMF impact from a specific power line can be found in the literature. A necessary condition for the normal functioning of ecosystems and the biosphere as a whole is a sufficient level of species diversity. Biological diversity is the basis for maintaining the ecological balance and sustainable development of the biota of regions
