| 摘 要： | 以湖北省马尾松为研究对象，在分析其干形的基础上，提出削度模型，进行了分析、比较。结果表明：Sohmacher所建立的削度模型具有较好预估能力，在此削度模型的基础上，建立了精确的商品材出材率估测系统，该系统可估计马尾松树干上任意直径的干长，任意高度处直径，商品材积及不同材种出材率，并用该系统编制了湖北省马尾松二元材种出材率表。

| Abstract: | On the basis of analysing trunk shape of masson pine in Hubei Province, the taper functions were producded and analysed and compared.The results showed that the taper function which was established by Sohmacher had better ability of estimation.On the basis of this taper function, a precise merchantable volume yielding rate system was established. This system can estimate the height on a certain diameter of the tree, the diameter of the tree on a certain height of the trunk, merchantable volume and various merchantable volume yielding rate. The merchantable volume yielding rate table of massion pine in two factors in Hubei Province was established for the part of this system. |
