Zibtsev S. Theoretical and methodological justification of forest monitoring in the zones of radioactive contamination as a result of the accident on Chernobyl NPP.

The dissertation research consist developing of theoretical foundations and methodological approaches for forest monitoring in areas of radioactive contamination, implementation of the system, as well as forecasts for radiological, environmental and fire situation in forests As the result of study peculiarities of accumulation of the dose-forming radionuclides in components of biomass of forests in different types site types were obtained, as well as their dynamics. Factors that contribute to the transfer of radionuclides in the timbers at phytocenosis and ecosystems were identified. The total reserves of radionuclides accumulated on a hectare of pine forest ecosystems were calculated. Based on assessment of species, taxonomic and systematic diversity on the monitoring plots integral indicators of biodiversity were calculated.
