Spatio-temporal organization of geosystems of the central part of Barguzinskii range

Abstract

Abstract The paper presents the results of the ecological study, with the analysis of landscapes and mapping of the area of the testing ground (80 km2). The testing ground is located in the Eastern Transbaikalia, covering the part of the Urbican basin and its mountainous frame. 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 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. It is established that the main factors influencing the landscape diversity are the aspect and steepness of the slopes, the composition and structure of rocks, the absolute height, the amount of atmospheric precipitation, and anthropogenic impacts. It is determined that the influence of the lithomorphic factor is widespread throughout the study areas, the hydromorphic factor is also important, the cryomorphic factor occurs additionally in the alpine and goletz zones. There are structural-dynamic characteristics of landscapes of a topological level. Structural features of topological geosystems are revealed, and large-scale maps of key areas are compiled. Map of the landscape-typological structure was created on the basis of the structural-dynamic and facies analysis of landscapes.
