| 摘 要： | 削度方程具有不受材种规格的限制、应用简便等优点,现已成为编制材种出材率表基础工作。本文以大兴安岭东部地区兴安落叶松天然林为研究对象,利用776株林木干形数据,通过分析、比较和评价4个削度方程拟合效果和预估精度,确定了兴安落叶松最佳削度方程。

| Abstract: | taper equation is the base model for compiling the merchantealetable, because it has the advantage of simpleness for application and not limited by the log size. Based on the stem profile data of 776 trees in Daxing'anling district of Heilongjiang province, the best taper eqution of natural Larix gemelini trees was developed by analyzing, comparing and evaluating the 4 Variable-exponent taper equations. |
