The paper considers the stability and transformation of geosystems of the Lena-Angara plateau, formed under the influence of natural and anthropogenic changes. The definition of the term «stability», the criteria for its evaluation, the map of stability of geosystems of the Lena-Angarsk plateau is given. The features of transformation of geosystems of the research area, the nature of anthropogenic load on them are revealed. Various blocks of transformation of geosystems are considered, the synthesis of knowledge about which allowed to create a system picture of transformation of geosystems of the territory. It is shown that the history of geosystems development in the research area is largely associated with the impact of the Baikal rift zone on the outskirts of the Siberian platform. It is noted that the spatial differentiation of geosystems is largely associated with blocks of the earth's crust and faults separating them, which determined the boundaries of geosystems in the rank of districts and provinces. The special role here belongs Zhigalov fault. The specificity of the spatial organization of geosystems within it is shown. It is established that at present the most intensive transformations are peculiar to the upper orling River area, where the formation of new young geosystems takes place. The materials are presented in the form of information synthesis of data and knowledge about the territory, based on the theory of geosystems academician V. B. Sochava, the results of many years of ground route research, cartographic information, decoding satellite images.
