本研究利用１７６块日本落叶松标准地材料，建立了与现行山本式材积方程相一致且符合适用性检验精度要求的削度方程。结合全林整体模型。林分自然稀疏模型及林分结构模型，分别立地指数、初植密度编制了日本落叶松林分材种出材量表，并对其进行了编制精度和适用性精度检验。结果表明，编表精度达９６％以上，适用性检验精度达９５％以上，可以在科研生产中应用。
In this study, 176 standard Japanese larch materials were used to establish the taper equation that is consistent with the current Yamamoto volume equation and meet the accuracy requirements of applicability testing. Combined with the whole forest model. The natural sparseness model and the stand structure model of stand were used to establish the timber scale of the Japanese Larch forest stand separately according to the site index and initial planting density. The precision and applicability of the data were tested. The result shows that the accuracy of the tabulation is more than 96% and the applicability test accuracy is more than 95%, which can be applied in the research and production.
