The paper describes the present the characteristic the up-to-date state and the dynamics of the forest vegetation in the south-eastern part of the Angara-Yenisei region. One of the promising methods of fulfilling a given task in order of the main types of boreal forests in mid-Siberia is to research the forest communities and to type them on the landscape and geosystems basis. In this case there is an attempt to make a transition from the phitocenotic classifications to the geographical-genetic ones. For this purpose we used the classical notions about the invariant of the geosystems and about the genetic type of a forest. We found the main regularities of the spatial-temporal dynamics and of the changes of the forest vegetation in this part of the region. In the process of making a legend to a fragment of the map of forest vegetation the derived forests and the indigenous ones were united. The following indicators of the growing conditions were chosen: a high-altitude belt, a geo-morphological complex, a relief element, the characteristics of the soils and the moistening as well as the position (the stage) in the age-regeneration rows. As an example we give a fragment of a computer-made map (the south-eastern part of the Angara-Yenisei region). To prepare the computer-made map of forest vegetation in the south-eastern part of the Angara-Yenisei region we used a multifunctional adaptable geo-information МАGIS-32 system, designed by the Siberian scientific–publishing and manufacturing centre of geo-information and applied geodesy. In the process of making the map we used a multifunctional adaptive geo-informative МАGIS-32 system. During the mapping the colour synthesised photos, obtained with the help of the Resurs-О satellite (we used the MK-4 camera), were automatically processed.
