A significant number of studies have been dedicated to the cultural and linguistic landscape of Siberia. Some of them show interest in exploring the domain of concepts that reflect the region's natural and social world, and its transformation. In the article, the author focuses on literary concepts that are being formed in regional literature. This is of particular importance when studying regional cross-border territories, such as Siberia, which is distinguished by a variety of textual "carriers" of images of real and imaginary spaces. The article aims to identify and analyze some key concepts of the writings of the second half of the 19th - early 20th centuries related to the memoir genres and created by exiles, scientists, publicists, writers, This helps show the multi-dimensionality of the cultural landscape of Siberia at one of the stages of its functioning. The methodology of the research is determined by the idea of the cultural and linguistic landscape of Siberia as a historical, cultural and socio-cultural constructed space of a transborder; contextual and conceptual analyses in combination with semiotic and historical-literary ones reveal the authors' representations of concepts, their semantic diversity and dependence on the communicative nature of the text. The analysis has shown that the concepts of Siberian nature, education and exile occupy a significant place in the domain of concepts of Siberian literature of this period. The content of the concept of Siberian nature is predetermined by one of the key features of the Siberian transborder - the focal location of the population and the associated idea of Siberian nature as wild, practically untouched by man. The relationship between man and nature in the analyzed writings is defined as enjoyment of nature as pure harmony and eternal beauty, harmony of nature and soul, human intervention in the life of nature. The first two aspects of the concept are consonant with its perception in the all-Russian culture and are the absolute dominants in the memoirs of the exiled Decembrists N.V. Basargin, A.E. Rosen, M.A. Bestuzhev. The third aspect reflects its Siberian specificity to the greatest extent; it is actualized in the works of Siberian writers S.I. Cherepanov, A.A. Cherkasov and Tomsk professor A.M. Zaitsev, where the concept is enriched with social, moral and ethical features: natural wealth, hunting, gold, wine, crime, sin, punishment. Education in the analyzed memoirs is a conceptual space; when creating it, the authors took into account the all-Russian literary and cultural contexts and the region's historical and social context. Thus, in the memoirs of the Siberian regionalists (oblastniki) N.M. Yadrintsev and N.I. Naumov, the concept has a special hierarchical structure, including education, training, enlightenment, and is refracted through the prism of caricature narrative. The most important is the ambivalent sign of the environment. The concept of exile, like the concept of education, reflects the multilayered nature of the Siberian cultural landscape. Thus, in the memoirs of political exiles Rosen, Bestuzhev, Kuchelbecker, Basargin, Lvov, the content of the concept is revealed in reliance on the image of Siberia as a country of exile that developed in the all-Russian consciousness. At the same time, the concept, whose structure the author defines as procedural and evaluative, was enriched with the following signs: Siberians, a new place, a new fatherland, cordiality, will, health, strength, acquisition, faith, creativity, friendship, etc. A native Siberian, the regionalist Yadrintsev became the exponent of the concept of Siberian exile as a form of colonization of Siberia. The overlapping of the identified concepts in a number of signs proves once again that they are included in the domain of concepts of one object - Siberian literature, which fixes a voluminous and systematic vision of the region's cultural landscape.
