06.00.00 Agricultural sciences
DescriptionOn the basis of the data gathered from various districts of Medial Siberia it is mounted, that at trees of the Siberian fir (Abies sibirica) for associations d1.3 =f (dп) and dп =f (d1.3) a build-up of the uniform normative (even at level of a wood band) leads to the significant magnitude of errors, but can be used at study of blanket regularities

Description
In the article it is offered to count the spatial sign with provision for mosaic-tiered structure of wood when estimating rising trees. It is noted that the diameter of stems has mediated (indirect) relationship with average distance to the nearest tree

01.00.00 Physical-mathematical sciences
DescriptionThe 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.

06.00.00 Agricultural sciences
DescriptionModels of model trees in the manner of equations for calculation of the current increase of trees at radius in cedar, mixed fir and pine plantings are received. At calculation of the current increase at radius and height using the diameter of a tree on height bosom without cortex, age tree and average distance from nearest tree on radius is recommended.

STRUCTURE OF MIXED FIR PLANTINGS BY DIAMETER, AREA OF THE SECTIONS AND AREA OF THE GROWING
06.00.00 Agricultural sciences
DescriptionQuestions of examination of the structure of the mixed plantings by three factors: diameter of stems on height bosom, area of the cross-section and area of the growing are considered in this article. It is determined that all rows of the distribution have expressed right-side location variant, which is possible to explain as age and spatial spottiness of the fir plantings
