Abstract


The results of the exploration of 137Cs distribution in the components of biogeocoenosis of mezoolihotrophical marshes of Polyssia Region of Ukraine are presented. The results show that during observation period the largest part of summary activity 137Cs is typical for tow (53.31 %) and peat (32.36 %). There is 12.96 % of summary (gross) reserve of radionuclide of marsh biogeocoenosis. The decrease of ediphictar role of ligneous species and its increase in moss tier (which mainly consists of sphagnum moss) is noted. The part of the moss tier in creating of the phytomass of coenosis is 64.42 % which is in 1.98 times more than part of ligneous.
