Novosibirsk, SB RAS Publishing House, 2002. - 356 sV monograph presents the materials of the Yenisei transect forest ecosystems research within the framework of the IGBP-NES international program Characterizes the natural conditions, the radiation regime of forests, the spatial distribution of precipitation and the geographical variability of evapotranspiration. The specifics of the forest education process in various sub-zones of the transect are considered, the influence of forest fires and other exogenous factors on it is shown. Materials covering the features of reforestation succession, radial growth and structure of annual tree rings, phytomass reserves and annual production of communities in northern forests are analyzed. The possibilities of using remote sensing and GIS technologies for inventory and mapping of the structure, condition and productivity of phytocenoses . Great place in the monograph is given to the dynamics of biogeochemical cycles in forest ecosystems of the transect. New data on the main carbon pools, variability of its annual accumulation by zonal ecosystems, input and expenditure items of the carbon budget and the influence of anthropogenic factors on the carbon cycle. Issues of sustainable management of boreal forests in the context of climate change and anthropogenic impacts are discussed. The book is designed for foresters, ecologists, biogeocenologists, geographers, specialists in the field of forestry and nature conservation, as well as students and graduate students .
