摘要
以马尾松人工林作为研究对象,用伐倒木样木数据,经干形分析和多指标精度比较,选定最佳的削度方程;通过树皮率方程和树高曲线方程进行计算机理论造材,依据各经济材种规格,编制出马尾松胸径树高二元经济材出材率表.经检验,以该方法编制的出材率表达到林业数表模型编制的精度要求.
Abstract
Taking the Pinus massoniana artificial forest as the research object,using data from felled tim-ber samples,the optimal taper equation was selected by the stem analysis and multi-index accuracy com-parison;through the bark percentage equation and the tree height curve equation,the computer theory was used to make timber,and according to the specifications of various economic timber species,the bi-nary volume table of Pinus massoniana economic timber was compiled.After verification,this method met the accuracy requirements of the forestry data table model compilation.
