摘　　要：在通过二类清查数据分析长白落叶松人工林主要立地条件的基础上,利用27块包含未成林期和幼、中、近熟、成熟4个龄级调查样地的样木和解析木基础数据资料,结合树高、胸径与年龄关系的常用树木生长模型,采用相对优势高法编制了长白落叶松人工林的立地指数表,并采用数式法编制了胸径地位级表。结果表明：对数曲线方程lnH=3.130lnA-1.041和lnD=9.605lnA-16.307分别是立地指数和胸径地位级的最适合的导向拟合曲线。以30 a为长白落叶松标准年龄,在12~21 m范围内划分10个立地指数级,编制形成立地指数表和胸径地位级表。检验结果表明所编制的数表精度高、适用性强,可全面、客观地评价该地区长白落叶松人工林林分,也为立地质量评定提供基础数据和理论依据。编制的胸径地位级表,不但能预测不同立地条件下林木胸径生长,也可直接用于立地质量评价,对于指导抚育间伐等经营措施的实施有重要意义。The forest management inventory data were used to analyze the main distribution of site conditions for Larix olgensis plantations. The data of sample and analysis trees（ including dominant and mean trees） from 27 sample plots in various site conditions were used to construct site index table and site class table by fitting the generalized mathematical models of age and height or diameter（ D,diameter at breast height）. The logarithm curve equations are the best fit among other selected curves. The standard age is identified as 30 years,and 10 index classes are divided within 12-21 m. Based on dominant height and mean D data,site index table and site class table are constructed by the expansion of the guide curve by using comparative dominant height and numerical expression methods,respectively. Both tables are applicable and accurate in evaluating forest quality and predicting the growth of L. olgensis plantations,and also can provide valuable data and theory foundation for evaluating site quality.
