摘　　要：文章以塞罕坝地区华北落叶松林为研究对象,抽取具有代表性的样本120株和检测样本17株,利用二元回归方程编制二元立木材积表。选取5个常用的二元材积模型,应用ForStat2.0软件,利用最小二乘法拟合计算模型参数,并利用F检验和未参与建模的17株样本对其精度和适用性进行检验,确定最适用模型为山本和藏式:V=0.000 084 D^(1.747 818)H^(1.005 244),利用此式编制了塞罕坝地区华北落叶松人工林二元材积表,旨在为林业生产实践提供科学依据,实现塞罕坝森林资源科学经营。Larch forests in Saihanba region were used as research objects in this study, and 12 0 strains as representative samples and 17 strains as detection samples were extracted to compile the binary stem volume table by using binary regression equation. Five common binary volume models were selected and ForStat 2. 0 software was applied in the research to study the accuracy and applicability of the models. The least square method was used for fitting the model parameters, and the F-test with 17 detection samples was then carried out. The results showed that the most suitable model was Yamamoto Kazuhide type ： V=0. 000 084D^1.747818H^1.005244 This model was then used in the compilation of the binary volume table of the larch forests in Saihanba region, providing a scientific basis for the practice of forestry production and the scientific management of the forest resources in Saihanba region.
