本文对目前常用的立木材积表的编制方法作了改进,采用随机、分散方法选测样木,应用回归分析方法修正因围尺测径造成的系统误差。编表的数学模型,采取中国林科院分析研究结果,二元材积表用山本材积式导算,一元材积表用全国材积式和浙江省双曲线树高方程导算。编成的浙江省各主要树种组二元立木材积表和4个区域的一元立木材积表,经伐倒木检验,精度较高。
In this paper, the method of compiling the standing timber volume chart is improved. The random and scattered methods are used to select the sample wood and the regression error is caused by the regression analysis method. Table mathematical model, the Chinese Academy of Forestry to take the results of the analysis, two-volume volume table using Yamamoto material-type guide, one-volume table using the National Volume and Zhejiang hyperbolic tree-height equation calculation. Compiled into the major tree species in Zhejiang Province, two sets of standing timber volume table and four regional one-lumen timber volume table, the wood fell by the test, higher accuracy.
