摘要: 本文提出一种材积表编制样本资料收集的新方法——样木解析法。即在标准地中采用随机或机械抽样方法选取样木,进行树干解析,获得样木生长过程;通过建立树皮系数与树皮率回归模型,将样木解析后的各龄阶去皮直径和去皮树积转化为带皮直径和带皮材积;一株样木可获得龄阶数个编表样本。经四川林校林场楠木材积表编制实践,有减少编表样本收集工作量、消耗林木少的优点,且能达到精度要求,为珍稀树种材积表编制样本资料收集提供了新的依据。

Abstract: A kind of method about construction of tree volume table-sample stem analysis, is suggested in this paper, In plot, sample trees are randomly selected and growing process is studied by stem analysis.The function about bark coefficent and bark ration is constructed by regression analysis.DBH and volume with bark in each age grade are estimated by the same factors without bark.In this way, several samples for volume table construction can be obtained from one sample tree.The practice with Phoede nanmu in school forestry farm proved that cutting and work ammont is greatly reduced but precision is high.

Key words: SAMPLE STEM ANALYSIS, STANDING VOLUME, PHOEBE NANMU, VOLUME TABLES
