摘　　要：林业案件查处过程中,滥伐或盗伐的林木无法测定树木胸径,通常是根据经验直接估计树木胸径后查阅《一元立木材积表》算出材积。如何利用树木地径科学地计算胸径和材积,本研究选择了马尾松、杉木、柏木、麻栎4个常见树种,通过实地随机抽样测量、数据分析、建模估算、分析汇总、实地验证,在三峡库区秭归县分析得出各树种地径与胸径的关系,编制出4个树种地径一元立木材积表,并在Excel中编制程序代入相关数据,制作出了地径一元立木材积计算表,选择树种后输入该树种的地径数值即得该树木的胸径和材积,实现了在办案过程中科学、快速、准确地测算立木材积的目标。In the process of investigating and handling forestry cases,trees that were cut indiscriminately or illegally,so the DBH(diameter at breast height)of the trees could not be measured.Usually,the volume was calculated by directly estimating the DBH of the trees based on experience and consulting the one-dimensional Timber Volume Table.How to scientifically calculate the DBH and volume by using the ground diameter of trees.In this study,four tree species of Pinus massoniana,Cunninghamia lanceola ta,Cupressus funebris and Quercus acutissima commonly seen in Three Gorges Reservoir Area were selected to analyze the relationship between ground diameter and DBH of each tree species through field random sampling measurement,data analysis,modeling estimation,analysis summary and field verification in Zigui County,in Three Gorges Reservoir area,and a one-dimensional volume table for the ground diameter of each tree species was prepared,In addition,the program was compiled in Excel to substitute relevant data,and a calculation table of standing volume of one yuan of ground diameter was made.After selecting tree species,the DBH and volume of the tree species were obtained by inputting the ground diameter value of the tree species,which realized the goal of scientific,rapid and accurate calculation of standing volume in the process of handling the case.
