摘　　要：本文提出Stine插值法用于树干材积求算及模拟造材,并以马尾松为例,将此法与中央断面区分求积法进行对比。对比研究中,采用不含截距项的线性模型,对插值法测算的全干带去皮材积和各材种出材量与中央断面区分求积法相应测算值进行回归分析。结果显示两种方法呈极显著线性相关,且插值法测算结果略高于中央断面区分求积法,幅度在1.6%～3.3%之间。因此Stine插值法可在一定程度上替代中央断面区分求积法。又因其在可拓展性上的优势,应用前景广阔。This paper developed Stineman＇s interpolating method for timber volume measurement and simulative log bucking.Comparative study between this method and Smalian＇s method was conducted on the basis of masson pine sample data,and the regression approach was employed to compare the difference between these two methods basing on linear model without intercept.Results showed that there was significant difference between these two methods,with Stineman＇s method having a little higher measured value（ranged from 1.6% to 3.3%）.It was concluded that Stineman＇s method can replace Smalian＇s method in practice to some extent,and it will have broad application prospect in consideration of its expansibility.
