GEOSYSTEMS OF ENVIRONMENTAL CONTCACT:SOME METHODOLOGICAL ASPECTS OF TYPIFICATION AND CLASSIFICATION

The problem of state assessment and change forecast in the geosystems is basis of modern landscapes studies. The main task is to study spatial-temporal self-organization of the landscapes structure under different of physical-geographic conditions, reflecting practically all changes in the environment for a concrete time period and space. With such an approach, a geosystem is considered as a system which forms and develops as united one and forms interdependent links with systems of other hierarchical level and with territorial attachment in general. The study of the vegetation communities of the geosystem of the environment transition zones of the Baikal region were showing the present tendency forming the facies structure of the landscapes of different areas of Pre'Baikal. This is has classification value and characterized intrazonal differences of the geosystem of the big regions. The vegetation communities of the geosystem of the environment transition zones is reflection of the physical-geographical conditions concrete territories and for period of time.
