Regularities of spatial distribution of damaged vegetation under conditions of regional and local air pollution (with reference to the impact zone around the Pechenganikel` mining and smelting plant)
- St. Petersburg Academy of Forestry Engineering (Russian Federation)
A special mathematical model for analyzing spatial distribution of vegetation damaged by air pollution was developed and verified. The model estimates the integral effect of global-regional and local (by scale) atmospheric pollution. This model makes it possible to separate the effects of both types of pollution and also to zone a territory depending on the extent of its damage. The developed theoretical approach was verified by data of field and laboratorial investigations in the zone that was exposed to discharges of the Pechenganikel` mining and smelting plant and also by means of the results of independent studies of Norwegian scientists. The zones of damage to the Scotch pine stand, which differed in magnitude of the load, were constructed. The regions where the concentration of nickel in berries of the bilberry was higher than the established maximum tolerance concentration were marked out. Areas of the specified zones were calculated.
