摘要： 研究以河北塞罕坝人工落叶松795株、内蒙古的苏格河人工落叶松45株、红花尔基沙地天然次生樟子松49株、那日斯太山地人工樟子松20株为例,对日本井上昭夫、黑川泰亨推导出的针叶树理论材积式进行适用性验证。从理论材积式和经验材积式计算的材积与实际材积之间的误差和精确度来看,理论材积式优于经验材积式。从而,进一步证明了理论材积式的适用范围的广泛性。

Abstract: The author applied the theoretical volume equation(TVE)that was derived by Inoue and Kurokawa to coniferous species.The sample trees were collected from four different regions:artificial larix in Sai Hanba(Hebei),artificial larix in Suge River(Inner Mongolia),natural secondary Pinus sylvestris in Honghuerji(Inner Mongolia),artificial Pinus sylvestris in Narisitai Mountain. The individual numbers are 795,45,49 and 20 respectively.The author compared the accuracy and precision of TVE with those of empirical volume equation(EVE)for each region.It could be judged that TVE is more efficient.In conclusion,the result of the study will support the universality and fitness of TVE.
