- Аннотация: In three-dimensional modeling of tree growth, it is suggested that a tree should be considered to consist structurally of sections periodically arising on the top of a tree and giving rise to virtual “trees,” these “trees” actually existing within the time interval before the appearance of the next section. The sections have dynamics different from the dynamics of the whole tree, and their biomass gradually dies off, which gives the effect of stem denudation from below observed in a nature. Analysis of the model shows the so-called “umbrella” effect as a limit form of a sufficiently old tree, which follows directly from I.A. Poletaev’s (1966) data on the restriction of tree growth in height by physical factors and from the S-shaped dynamics of tree biomass. The analysis also leads to the conclusion on the impossibility of S-shaped dynamics of tree phytomass (the P type of growth).
