Modern Structure and Trends of Transformation of Geosystems of the Pre-Baikal Region

Abstract

The purpose is to study the modern structure and trends of transformation of geosystems of the Pre-Baikal region. Materials and methods. The work is based on data from field route observations, analysis of thematic maps, results of expert interpretation of satellite images, generalization of literary sources using historical, landscape-oriented and comparative geographical methods, GIS. Results and discussion. The study of the modern structure and trends of transformation of the geosystems of the Pre-Baikal region is an urgent and important topic of research, since part of the territory belongs directly to the geodynamically active Baikal Rift Zone (Baikal Ridge), its so-called compensatory deflection (Pre-Baikal depression) and the ancient Siberian platform (Leno-Angarsk Plateau). The territory is contrasting and diverse. Gas production and forestry activities are widely represented. The development of geosystems was influenced by tectonic and geodynamic factors. The research area is confined to the outskirts of the Siberian Platform, the Pre-Baikal Depression and the Baikal Ridge. Conclusions. The geosystems of the Pre-Baikal region are affected by the Baikal rift zone and have features characteristic of the Central Siberian Taiga-plateau region in the west and south of the territory, the Baikal-Dzhugdzhur mountain-taiga region in the east and the South Siberian mountain region in the center and northeast.
