The sketch of the yield table of modal pine stands based on the principles of dynamic typology

Abstract

To study the dynamics of taxational specifications, a typological method was chosen; this approach was based on the principles of dynamic typology. The material was selected according to forest types, on the basis of which the averaged characteristics of the dynamics of taxational characters with age were calculated with the use of graphical or analytical interpretation.

The study object is pine modal stands growing in the in the Karaulnoye district forestry of the training and experimental forestry at Reshetnev Siberian State University of Science & Technology.

The study was conducted in two types of forest:

• greenmoss pine forest representing a primary forest type;
• sedge-grass pine forest representing a nominally primary forest

As a result of the conducted research, both data of forest management and the materials collected through studies have been elucidated and analyzed. It is established that over time the primary type of forest (greenmoss) transitions into a nominally primary forest type (sedge-grass). As a result, these types of forest were combined, and for them, as for one single type of forest, a yield table was compiled. In the course of the analysis of dynamics of the basic taxational specifications, such as height, diameter and standing volume, it is established that the data on Karaulnoye forestry surpass the values on known standards of the table by N. E. Supriyanovich. This indicates that the stands being studied are more productive than the stands of the Angara region.

The table can serve as an initial basis for the characteristics of growth, increment and productivity of pine forests for forest conditions of the riparian part of the Yenisei River.
