| 摘 要： | 根据人工林和天然林红松的管胞长度、生长轮宽度、生长轮密度和晚材率等性能指标的测试结果，采用最优分割法分析得出：人工林红松幼龄材与成熟材的界限为15a，天然林红松幼龄材与成熟材的界限为35a。通过人工林和天然林红松解剖、物理性质的比较，总体上表现为幼龄材性质低于成熟材，人工林材性劣于天然林。

| Abstract: | The tracheid length, growth ring width, growth ring density and latewood percentage of the wood from Pinus koraiensis plantations and natural forests were tested by using optimum method of classification. The result showed that the boundary lines of juvenile wood and mature wood of planted and natural Pinus koraiensis were the 15 th year and the 35 th year respectively. The property of juvenile wood was lower than that of mature wood and the performance of planted Pinus koraiensis was worse than that of natural Pinus koraiensis according to the comparison on their anatomical and physical properties. |
