摘要
修枝作为一种传统的森林经营措施,在调节林分结构、调控林木生长、提高木材质量、维持林分稳定性等方面具有重要作用。探索科学合理的修枝技术是国内外林业科技工作者的研究热点。文中综合国内外的研究进展,从林内小气候、林下植被以及林地土壤3个方面阐述了林木的修枝效应,以期揭示林木修枝对环境的作用规律,为人工林修枝技术的研究与应用提供依据;同时指出当前我国林木修枝工作中存在的问题,并提出展望,以期为今后的研究和生产实践提供参考。
Pruning is a traditional forestry management method that plays an important role in regulating forest structure,putting forest growth under control,improving timber quality,and maintaining forest stability.Exploring scientific and reasonable pruning technologies has been a research hotspot at home and abroad.Based on the domestic and overseas study results in recent years,we described the effects of pruning on the forest environment from 3 different perspectives of the forest microclimate,understory vegetation and soil qualities,with the expectation to reveal the role of pruning to environment and provide references to the research and application of planted trees pruning in the future. Meanwhile,we preliminarily pointed out the shortages and the prospects about the trees pruning in China,which could be used as references for the future studies and practices.
