AREAL AND ECOTYPOLOGICAL COMPOSITIONS OF THE FLORA OF THE PLANT COMMUNITIES OF THE ENVIRONMENT CONTACT SITES (SOME AREAS OF PRE’ BAIKAL AS AN EXAMPLE)
The study of the vegetation communities of the environments trasition environment zones of the Baikal region were showing the present tendency forming of the vegetation for different areas of the Pre’Baikal. These communities can be the regional models for indication of the present processes and the past changes in the structure of the vegetation in different ecological conditions. It’s shown that ecotones and plant communities reflection the paragenese in the vegetation structure are indication of the structural and dynamic features of the vegetation cover organization at Pre’ Baikal at all. There has the classification value and characterized intrazonal differences of the vegetation community’s structure of the big regions. The ecotones and paragenese in vegetation structure at the research region is reflection of the physical-geographical conditions of its formation for the concrete period of time.
