ABSTRACT

The problem of state assessment and change forecast in the whole ecosystems and in the vegetation structure in particular makes a basis of modern biogeographical, geobotanical, biocenological and ecological studies. The main task is to study spatial-temporal self-organization of phytocenoses under different physical-geographic conditions reflecting practically all changes in the environment for a concrete time period. With such an approach, a phytocenosis is considered as a system, which forms and develops as united one and forms interdependent links with systems of other hierarchical level, with ecotopes conditions, and with territorial attachment in general. As methods for definition of long-term trends in the dynamics of vegetation cover structure are mainly at different stage of development, it causes to researchers a series of problems from choice of concept basis to notions and terms establishment for the revealed processes and states of the plants and of the ecosystem in general. Solution of such tasks inevitably results in the necessity to correct the existing understanding of processes occurring in vegetation and allows outlining a direction of their development in the system of natural factors of any territory. This results in the appearing of basis for determination of age, site and role of current states of phytocenoses in successional systems. It is necessary for this to reveal the peculiarities of phytocenoses composition and combining connected with natural dynamics of environmental factors, environmental factors with impact of the anthropogenic factors as well. To study structural-dynamical organization of phytocenoses under transitional different environmental conditions of a definite genesis and territorial attachment it’s necessary to use the definitions of “ecotones” and “paragenese” (an object) as phytocenotically separate natural phenomena characterizing the structural peculiarities of cenoses appropriate for interzonal, interbeltic, intrazonal and intrabeltic environmental conditions as well.
