Abstract
The article presents the results of a study of the dependence of the diameter of the Daurian larch at chest height on the diameter of the stump growing in the conditions of the Putorana Nature Reserve in Taimyr Forestry. As a result, the assessment of the tapering of the lower part of the trunk of the larch was performed. The approximation of the diameters correlation was performed using a linear regression model with a determination coefficient of 0.90. A comparative analysis of the data on the tapering of larch shape in the study area with data from the Far East and with all-Union standards was carried out. It was found that the lower part of the larch trunk in the buffer zone of the Putorana Nature Reserve is characterized by a higher tapering with a diameter of 32 cm at the root neck relative to the all-Union standards. The ratio of larch diameters found in the study area in the diameter range of 18–32 cm corresponds to the data of the table by A.M. Mezhibovsky and V.E. Schultz.
