GIS-aided simulation of spatial distribution of some pollutants at   "Stolby" state reservation
  Reserved territories seem to be best reference sites of wildnature, where the long-term observations are carried out. Simulation model of spatially distributed processes of contamination of the state reservation is developed, and the dynamics of some pollutants is studied. An issue of the generalized evaluation of an ecological system status is discussed.
