I am a botanist and forester. PhD. I am studying the diversity of forest types and dynamics of forest vegetation in the Urals (Russia). I studied patterns of natural and anthropogenic dynamics of forest vegetation in the mountains of South and Middle Urals. I am doing research since 1991.Complex forest geobotanical researches were carried out. Full profile soil cuts were put. Different moistening conditions (fresh, occasionally dry; stable-fresh; fresh, occasionally wet; wet, wet occasionally) are presented in the ecological profile. The landscapes diversity, the moisture regime, soils and complex ecotone effect resulted in a high diversity of forest types and their specific structure.I received information on the specific structure, productivity of forests, reforestation. I studied the natural and secondary forests. Three hypotheses have been formulated and tested: 1 – the divergence of development lines of forest ecosystems, depending on the type and intensity of the external action; 2 – the descent of the different development lines within a native forest type; 3 – the leveling of differences between the various forest ecosystems under the influence of similar violations. The work initiates the development of a new interdisciplinary field of science, which is based on an understanding of non-linearity, adaptability, the fractal and network organization of ecological systems.To describe the alternative development of vegetation after clear-cutting differential equations systems were used.
