Presented are the results from an ecologo-geographical study and mapping of forest territories in the northwestern part of Western Siberia. State-of-the-art GIS technologies are used in processing space images and compilling landscape maps. Problems relating to determination of the degree of anthropogenic disturbance and resistance of forest geosystems on northern territories are considered.
Keywords: resistance of taiga geosystems, landscape mapping, structural-dynamical approach, anthropogenic load, classes of geoms.
