摘　　要：准确估测盗伐木材积对评估森林盗伐后的损失具有重要作用。本文针对树木被盗后现场只留伐桩的情况,提出了一种基于地径形高法的被盗木材积复原技术,即:首先测算出被盗木周边与其生长状况相近树木的地径形高,然后用平均地径形高结合被盗木地径值求算出被盗材积。试验采用刺槐、麻栎两树种各 24 块样地,每样地各取 10株样木对该方法进行了材积复原效果研究,结果表明:用来测算平均地径形高的样木株数越多,材积复原效果越好,当样木株数从 1 株增加到 4 株时,材积复原误差即可有效控制在 10%以内。由此认为,该方法是一种复原误差可控、实用性良好的盗伐材积复原技术。It is important to estimate the volume of stolen trees accurately for the assessment of economic losses. Due to the fact that only tree stump was left after the tree was stolen, this study proposed a technique for calculating the stolen tree volume based on ground diameter form height. Firstly, to measure the ground diameter form height of trees around the stolen one which were similar to the stolen trees. Then to calculate the volume of stolen tree using the average ground diameter form height combined with the stolen tree’s ground diameter. In this experiment, 24 plots of Robinia pseudoacacia and Quercus acutissima were investigated, and in each of the plots, 10 individuals trees were measured respectively. The data from the investigation were used to recover the volume of stolen trees. The results showed that the more sample trees used to measure the average ground diameter form height, the better the recovered results will be. When the number of sample trees increased from 1 to 4, the error of recovery volume can be controlled under 10%. Therefore, it is considered that this method is a practically useful technique for recovering the volume of stolen trees and its recovery error is controllable.
