Abstract The paper presents the results of the ecological study, with the analysis of landscapes and mapping of the area of the testing ground. The testing ground is located in the Eastern Transbaikalia, covering the part of the central part of Primorskii Range and sourth-eastern macroslope of this mountain range (having an easterly aspect for the Primorskii Range). For the analysis of the structure of geosystems and the estimation of disturbance, the basic geosystem approach is applied to modern geoinformation-cartographic and remote methods. Based on V.B. Sochava’s theory of geosystems it is assumed for use in processing and ordering a large volume of information. In the paper we analyzed the regional background and main factors of the landscape differentiation of the study areas. The pyrogenic impact, which increased by the 21st century and caused the transformation of the natural structure of the Baikal mountains, caused the need to improve the methods of mapping the geosystems of topological level, their dynamics, landscape-forming processes and individual local phenomena. We identified negative digressions of geosystems for the period 1989-2019 at the experimental site, when 42% of 100 km 2 of natural systems of highlands, mountain-taiga middle mountains and lowmountain-slope forests were lost.
