A deviation from tree height growth trends of Scots pine is analyzed. They have a periodicity and vary both by the amplitude and period. At average the value of period is 40-50 years and has a significant variabil-ity. It depends on longevity of tree life and age classes. The deviation depends on relation between the trees in stand. An abiotic factors effect increases and comes to the fore under constant of actual adverse environment conditions for growing
Accounting stands (1959, 1977, 2007) revealed reduction of areas dominated by deciduous species and larch in the State Nature Reserve "Stolby". Area stands of fir and pine increased. Area stands of cedar and spruce didn’t change over the last 50 years. Deciduous stands differs rapid accumulation of stock, but they have productivity lower then conifers. There is a shift in even-aged stands to multiple-aged stands in coniferous formations. They are close to a climax state. Cedars grow on the type of the even-aged stands, because they appeared in the area recently
The aim of work is to get prognostic equations, taking into account the natural growth of pine forest stands
of Krasnoyarsk forest-steppe along with influence
of forestry arrangements and elemental factors. Dependences of weight average diameter and mean square deviation from age and plantation density were received in the article.
The aim of work is to get prognostic equation, providing analytical description of height dependence on diameters by thickness of steps for forest stands of Krasnoyarsk forest-steppe.
