沙县杉木、马尾松、阔叶树地径一元材积表编制的研究

Studies on the Compilation of One-Dimensional Volume Table for the Ground Diameter of Cunninghamia lanceolata, Pinus massoniana and Broad Leaved Trees in Shaxian County

地径材积表是林业生产、科研和管理的基础工具。本文结合县级森林资源连续清查样地调查,通过样木地径、胸径成对值测定,建立地径——胸径回归关系,并利用现有省定的一元立木材积表,编制了沙县杉木、马尾松、阔叶树地径一元材积表。

The volume table of ground diameter is a basic tool for the produc-tion, scientific research and mansgement in forestry. This article integrated theplot surveys of continuous forest resource inventory at county level to establishthe ground diameter-dbh regression relation by means of the determination ofpaited values of sample-tree ground diameter and dbh and compiled the one-di-mensionai voiume tabie for the ground diameter of Cunninghamia lanceolata, Pi-nus massoniana and broad leaved trees in Shaxian County by using the presentone-dimensional standing volume table defined by the Province.
