| 摘 要： | 对秦岭油松人工林进行了调查，研究了不同营造方式对油松林分生长的影响。结果表明:油松人工栽植林树种组成较复杂，林分密度较小，干形尖削；油松飞播林中几乎是纯林，密度较大，树干通直圆满。两种不同营造方式对林分直径、材积生长量影响差异显著，但对树高影响不明显。油松飞播林在前9～10 a材积生长速度大于人工栽植林，在10～21 a材积生长速度明显低于人工林。

| Abstract: | Based on the investigation of Pinus tabulaeformis plantations in the Qinling Mountains,the effects of different forestation patterns on the stands' growing were studied.The results showed that the plantations by seedling transplanting were more complicated in tree composition than the plantations by aerial sowing.They obviously contain other mixed trees besides the predominant tree of P.tabulaeformis.Because of low population densities,the stem form in the plantations by seedling transplanting was tapered.I... |
