| 摘 要： | 分析了不同间伐强度对侧柏(Platycladus orientalis)人工林林木生长的影响,对徐州市实施不同间伐强度的50年生侧柏人工林进行了研究。结果表明:胸径、冠幅、单株材积的生长量都随着间伐强度的加大而有了明显的增加,表现为间伐2次间伐1次未间伐,经方差分析,差异显著;间伐对侧柏人工林树高的生长几乎没有影响,3种林分的树高生长量在整个生长过程中都保持较高的一致性,经方差分析差异不显著;林分蓄积量随着间伐强度的加大而逐渐减小。

| Abstract: | Study was conducted on effect of different intermediate cutting intensity on growth of 50-year Platycladus orientalis plantation in Xuzhou, Jiangsu province. The result showed that DBH, crown size and single tree volume of the plantation increased with intensity of intermediate cutting, while stand stock decreased. But different intermediate cutting density had no effect on height increment. Analysis on variance showed the same result. |
