The natural and anthropogenic factors of the functioning of floodplain-valley complexes of the Upper Angara region

In order to identify modern trends in the functioning of geosystems in the Upper Angara region, the natural conditions of their development and anthropogenic transformation are considered. The main landscape forming factor is the features of the morphological structure of the surface exposed to the influence of modern exogenous processes - aeolian, slope-gravitational, fluvial. Landscape discreteness, as well as the intensity of the manifestation of relief formation processes, are due to the implementation of economic activities, among which the most pronounced are urban-industrial, communication and transport, agricultural and recreational. An assessment of the activity of exogenous relief formation within a number of morphological elements of the floodplain-valley complex has been carried out, which can serve as a basis for solving the problems of predicting the risk of manifestation of hazardous processes, when carrying out measures to optimize nature management, as well as when solving problems of nature protection.
