摘要
针对我国人工针叶林存在生态功能不够强、抵抗自然灾害能力弱、地力衰退等问题,研究了3种经营措施对杉木近熟林分的影响,结果显示杉木近熟林进行大强度间伐套种鹅掌楸后,林木的平均高生长、平均胸径生长、林分蓄积量、林分的经济和生态效益均高于其他2个处理(只间伐和不间伐)。其结果为近熟人工针叶纯林经营提供了一种非常值得推广的经营模式。
The artificial coniferous forest in China has some problems,such as weak ecological function,weak ability resisting natural disasters and land degradation.It was studied the effects of three management measures on the near-mature stand of cunninghamia lanceolata(lamb.)hook.The results showed that after inter-planting the Liriodendron chinense with intensive thinning,the mean height growth,mean DBH growth,stand volume,economic and ecological benefits of the trees in the near-mature stand of cunninghamia lanceolata(lamb.)hook were higher than those in the plots with the other two treatments(only thinning and no thinning).It provided a management model that is very worthy for the extension in the near-mature artificial pure coniferous forest.
