Abstract
In order to solve various research tasks, actual morphometric parameters of trees and forest phytomass assessment data are of great scientific interest and intended for multipurpose applications. However, often this important original information is stored in the archives of the researchers or institutions, will not be published and is not available for detailed analysis and reliable comparisons. The records of morphometric parameters and above-ground phytomass of the Siberian larch (
Larix sibirica Ledeb.) trees, measured on coordinate sample plots established in Eastern Khentey, northern Mongolia are presented in the paper. The morphometric parameters and phytomass of the trees are considered as the main characteristics, that determines course of the processes in forest ecosystems, and might be used for environmental monitoring, sustainable forestry, forest productivity modeling, taking into account global changes, studying the structure and biodiversity of forest cover and assessment of forest carbon sequestration. The study of morphological structure and phytomass of trees seems necessary because the various structural parameters and fractions have different content of nutrient elements and different contribution to annual production of forest stands. On the basis of biometric statistics, allometric equations relating morphometric and production parameters of the larch trees have been calculated, which can be used in ecological modeling, forest inventory and thematic forest interpretation of aerial- and satellite scenes in northern Mongolia.
