摘　　要：毛竹是乔木状禾本科植物,具有强大的克隆繁衍和空间扩展能力。开展毛竹皆伐是毛竹扩张地修复的一种方式。本研究通过监测毛竹皆伐后的各生长因子发现,在皆伐强度经营措施下,毛竹在阔叶林中能续存3年左右,此后基本没有新竹存活;毛竹立竹度、产笋量、新竹数都是逐年降低,直至为0;死笋率逐年增加,直至全部死亡;胸径和株高也逐年降低。因此,毛竹的皆伐措施是一种比较有效的毛竹扩张防控措施,有利于对被扩张林地林分的保护与重建。Phyllostachys edulis is an arborous gramineous plant, which has a strong ability to clone, reproduce and expand space. Clear cutting of Phyllostachys edulis is one of the ways to restore the expanded area of Phyllostachys edulis. Through monitoring various growth factors after clear cutting of Phyllostachys edulis, this study found that under the clear cutting intensity management measures, Phyllostachys edulis could survive in broad-leaved forests for about three years, and after that, almost no new bamboos survived. The standing bamboo degree, shoot yield, and number of new bamboos of Phyllostachys edulis were decreased year by year until dreasing to zero. The rate of dead shoots was increased year by year until all of them died. The diameter at breast height and plant height was also decreased year by year. Therefore, clear cutting of Phyllostachys edulis was an effective measure to prevent and control the expansion of Phyllostachys edulis, which was conducive to the protection and reconstruction of the expanded forest stands.
