THE PRODUCTIVITY AND STRUCTURE OF THE GROUND PHYTOMASS OF THE PINE IN THE MIDDLE URALS

The purpose of the work: studying the laws of accumulation and distribution of the ground phytomass of trees and woods of the common pine in the Urals and compiling the Tables of the biological productivity. The laws of distribution of the number of the first order branches have been studied by the different indicators and the two-dimensional distributions of the branches mass by the thicknesses vertical profile of the crown. The laws of change of some qqualimetric indicators have been examined. The normative materials for the Middle Urals South taiga subzone have been developed to evaluate the reserves of phytomass on the level of the branch, of the tree, of the wood, necessary for the forestry practice. The normatives differentiate by the types of the forest, by the heights categories, bonities. The offered normatives reduce the expenditures with the forests arranging as the necessity of the experimental areas for the evaluation of the phytomass are not requiredAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
