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。Taking the Pinus massoniana artificial forest as the research object,using data from felled timber samples,the optimal taper equation was selected by the stem analysis and multi-index accuracy comparison;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 binary volume table of Pinus massoniana economic timber was compiled.After verification,this method met the accuracy requirements of the forestry data table model compilation.
