Abstract:
The results of the studies have shown that the total C reserves of the dark coniferous forest phytomass of the southern taiga in the south-eastern part of the Western Siberia vary from 75.8 to 129.0 t/ha in secondary birch forest and from 48.9 to 110.5 t/ha in fir forests. The analysis of the production process in dark coniferous forests of the southern taiga done using such parameters as absolute value of the C biomass growth, specific annual production of wood and efficiency of assimilation apparatus work, has determined a few differences in the intensity of the NPP phytocenoses which differ from each other by the type of the main plant formation (with or without change of species). The typical feature of the secondary birch forests is the high efficiency of the assimilation apparatus work (2 4 times) than in fir forests. The data analysis only for pure birch forests has determined the connection between the intensity of C organic matter production and C mass in leaves. The total specific production of the growing crop decreases with age: in birch forests from 5.4 down to 3.1%, in fir forests from 8.2 to 5.5%, making 2.7 % at age of 170 years.
