tive movements of geological structures ta ke place* Lowering of surface heights causes the accumulation of sediments and fading of deep erosion, the fresh erosion forms disap pear and they are covered with vegetation* When the bottoms of watercourses are filled with sediments, they are widened and further they go out the limits of the erosion valle ys* River plains become twisting, terraces are lowered and merged and the watercourses' valleys acquire flat and weakly prominent profile, due to that the peripheral parts are greatly watered and bogged* The general relief planation takes place, its dismember ment is decreased, vast alluvial flat low lands are formed* The water flow highers the subsoil waters' level, intensifies frost phenomena with the development of the correspondent relief's forms on dry valleys and bogs* The constant redundant moistening causes the progressive bogging which is spread pri marily in elementary watercourses, then ext- raflat-bottomed valleys are bogged and at last the interfluve is bogged as well* In the bogs structure pool and lake complexes are widely used* The flat lowlands with almost total bogg ing and dense net of lakes represent the fi nal result of the plains development in the range of the lowering units* In the forest composition the part of wood species, resistant to redundant moistening: cedar, alder, willow, white birch is increa sed and due to the progressing of frost the part of larch stands is also increased* Wa tering of the landscape lowers the risk of fire occurrence and damage by pests, so the areas of native communities are increased* Supperaqueous and subaqueous natural comp lexes are widely spread* The introduction of nutrient substances is observed, which hig hers the trophness and in the southern parts of the forest zone it causes the emergence of saline natural complexes* Due to the general increase of moistening, watering, surface frost, wet mild macrocli mates are formed* All the enumerated natural phenomena, ta king place in the landscape, are represented on space images not only from the point of view of the quality, but the quantity as well* The representation is measured by the absolute value and the areas ration of the various classes natural complexes* As a result of that in the range of the tectonic structures and units the homogene ous morphological structure is formed as well as relatively the same ecological regimes of PTK* Thus, it is not accidentally that the borders of the landscapes and terrains coin cide with the fault and lineaments with the straightened river valleys where rather sharp change in the structure takes place* As an example we'll take the fault system which separates the Enisel Chain of Hills from the Siberian platform* These faults are distinct ly seen on all the space images* We see that the forest composition and landscape bogging are changed at the borderline of those struc tures • As a result of the landscape-morphological investigations the landscape basis is created to perform the thematic and applied resear ches with various trends* The landscape ba sis represents the series of conjugated dif ferent scale maps of PTK of various ranks: landscapes, terrains, stows, facies and their typological divisions (kinds, classes, types)* The maps are accompanied by the detailed le gends (the system of conventional denotati ons), landscape profiles, structure and com position tables with the emphasizing the con jugated components and PTK elements diagrams, the interpreted space-air images and other auxiliary graphic and text materials, open ing the structure of natural complexes* The landscape basis serves as the Initial mate rial to compile the series of the conjugat ed different scale maps: of forests, soils, bogs, quatenary deposlsts, various technic al, food, medicinal and forage resources, propagation and migration of food-animals, game-preserves of different classes, local deseases of animals and people, the practi cability of forests with the help of various transportation means, construction engineer ing and etc* On the landscape basis the dy namic phenomena are successfully studied which specifically occur in various PTK: de velopment processes of negative consequences of wrong agricultural or forestry measures (e*g* in the cutover areas), the hotbeds and the dynamics of pets* propagation, forest fires and postfire forest regeneration, wa ter balance and local climate, other useful and harmful changes of PTK as a result of people's activity* Estimating the PTK react ion on various external effects, it is pos sible to plan measures on nature protection locally* There is no doubt about the close interconnection of PTK and their structure with the tectonic movements of the earth's crust and the geographical structures* This is one of the ways to study the geological structure of the earth's crust and the recon naissance of useful minerals* Hie landscape basis has been already implemented into fo- rest inventory practice (various landscape- statistical express-methods), forest manage ment and forestry arrangement* One of the tasks of the landscape basis application is to compile the state land cadastre, to arran ge the rational nature use, production dist ribution, settlements, recreational zones, to estimate the suitableness of PTK for the certain type of the functional utilizarion* All that promotes the complex inter-branch arrangement of the territory, Increases the economical effect from its utilization*
