BIOLOGY PRODUCTIVITY OF BOG IN FOREST-STEPPE
In the article new experimental data are given the biological productivity of the plant communities in the forest-steppe of West Siberia. The stock of mortmass in eutrophic swamps change from 1500 until 2800g/m2, in ryams are about 4000 g/m2. The stock of living phytomass are minimum in ryam, they increase to 4000 - 6200 g/m2 in the eutrophic swamps. Net primary production in ryam of forest-steppe is about 600 -700 g/m2/yr and determined mainly by the plant community of ecosystem. Mosses and belowground fraction of plant are the major contribution to NPP. The maximum difference in the production is manifested between the different habitats.
