| 摘 要： | 为研究抚育措施对侧柏人工幼龄林生长的影响,对北京郊区山地不同立地条件下的侧柏人工幼林进行了不同强度抚育试验。结果表明:抚育1年后对侧柏幼林生长影响不显著,5年后影响显著,其中,在阳坡薄土条件下,中度抚育措施侧柏树高、胸径、单株蓄积生长量最大;在阳坡厚土条件下,强度抚育措施侧柏树高、胸径、单株蓄积生长量最大;在阴坡厚土条件下,随着抚育强度逐渐增加,侧柏各指标生长量亦逐渐增大。

| Abstract: | In order to study the effect of tending measures on growth of young Platycladus orientalis forest,tending experiments of young Platycladus orientalis forest with different intensities were conducted under different conditions in the suburbs of Beijing.Result shows that there was no significant effect on growth of Platycladus orientalis in one year after tending,and the effect was significant after 5 years.Among them,under moderate slope condition,the height growth,DBH & individual growing stock are the highest by adopting moderate tending measures.The growth of Platycladus orientalis increase with the increase of tending intensity under the thick soil in the shady slope,and the growth of Platycladus orientalis increase gradually. |
