  Description

  On 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

  DEPENDENCE OF THE CURRENT TREE INCREASE FROM MORPHOLOGICAL AND SOCIAL FACTORS ON EXAMPLE OF TIMBER STANDS OF EAST SIBERIA

  06.00.00 Agricultural sciences

  Tags: age of a tree diameter on bosom height cedar model fir pine average distance current increase
  Description

  Models 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.
