摘要
推导出一个一致性材种出材率预估模型系统。介绍了单木理论材种出材率计算实现程序，以杉木为例，给出了计算结果。最后对削度方程及材种出材率有关问题作了分析和讨论。
A compatible merchant volume ratio
prediction model system was developed.The program of computing theoretical merchant volume
ratio based on individual tree was presented and merchant volume ratio of Cunninghamia
lanceolata which was taken as an example was ealculated,some characteristics of taper equation
and results were analysed and discussed,
