| 摘 要： | 为弄清间伐对落叶松人工林内环境因子,进而对落叶松林内天然更新的影响,在辽东山区对40年生落叶松人工林进行了5种不同强度的间伐试验(分别为0%、10%、20%、30%和40%)。间伐后,对环境因子和更新状况进行了观测。结果表明,林冠开阔度随间伐强度增大而增加,间伐后其林冠下光量子数量、地表平均温度、不同层次土壤平均含水量与空隙度大小成线形关系;落叶松人工林间伐一年内,更新树种丰富度没有显著变化,而更新密度和更新频度都明显增加(p<0.05)。更新树种数量增加与树种特性有关,增长幅度为阳性树种>耐荫树种。所有的更新树种中,对林冠开阔度变化响应最大的是黄波罗(Phellodendronamurense)。实验结果证实了辽东地区落叶松人工林间伐后,更新数量变化与周围保留的树种分布、树种特性和立地条件有关。图9表2参43。
