Mapping of geosystems in the south of the Yenisei Siberia for environmental assessment

Abstract

Landscape mapping of the southern regions of Middle Siberia within the territory of the planned complex investment project “Yenisei Siberia” on collateral economic development of 3 regions (Krasnoyarsk Territory, Republics of Khakassia and Tyva) is carried out. Works were performed with using uniform geosystem classification based on systemic hierarchical approach to identification of a taxonomy of landscape units. It considers positioning of concrete territories and typological ranges of regional geosystems in the system of physical geographycal regionalization. The technique of mapping was based on the V.B. Sochava’s doctrine about geosystems and the principles of creation of hierarchical structure of geomers by integration of structural and structural-dynamic indicators. Own ideas of authors of geosystems classification received from experience of landscape mapping of other regions in the South of Siberia by drawing up the map are used. As a result of research a big variety of geosystems is revealed on the map through display of spatial differentiation of areals of distribution of geomers of a rank of group of fatsias is revealed. The complexity of landscape structure is caused by position of the territory of researches of a joint of four landscape regions.
