摘要
修枝是培育优质人工林无节材的主要营林措施。为了满足人们对高品质木材的需求,众多学者开展了修枝对人工林生态系统影响的系列研究。文中在总结国内外人工林修枝研究成果的基础上,分别从修枝对人工林生长、林下植被发育、土壤肥力、木材材性的影响等方面,综述了修枝对人工林生态系统影响的研究进展;指出目前人工林修枝研究中存在的问题,提出今后应加强人工林修枝的理论基础研究、制订不同树种人工林的修枝技术规范和标准、加强修枝对人工林生态系统长期影响的定位研究、研发适应山地作业的修枝机器人等建议,为人工林修枝及无节材培育提供科学依据。
Pruning is the main measure that is used in forest management to cultivate knot-free timber.In order to meet people’s demand for high-quality wood,many scholars have carried out studies on the impact of pruning on plantation ecosystem,and achieved remarkable results.Based on the review of research on plantation pruning at home and abroad,this paper summarizes the research progress in the effects of pruning on plantation ecosystem from the aspects of plantation growth,understory vegetation development,soil fertility and wood properties,and points out the problems existing in the current research on plantation pruning.It is suggested that the theoretical research on pruning in plantations should be strengthened,the technical specifications and standards for pruning of different tree species should be formulated,the research on positioning the long-term effects of pruning on plantation ecosystems should be promoted,and plantation pruning robots suitable for mountain operation should be developed,so as to provide the scientific basis for plantation pruning and knot-free timber cultivation.
