摘要
通过选择经营周期短经济效益明显的树种桉树与经营周期长生态效益可长期发挥的树种红锥、枫香、火力楠等进行混交复合经营试验分析,旨在改变桉树纯林森林经营带来的弊端,探索多树种经营,多效益实现的森林经营模式,为森林可持续经营,森林经营单位可持续发展提供参考。试验采用桉树∶红锥∶枫香∶火力楠=6∶2∶1∶1;桉树∶红锥∶枫香∶火力楠=4∶2∶2∶2;桉树∶红锥∶枫香∶火力楠=2∶3∶3∶2三种造林模式,试验林经过9 a生长,发现桉树∶红锥∶枫香∶火力楠=4∶2∶2∶2的经营模式森林蓄积量高,且因红锥、枫香、火力楠占比较高,林分的森林生态效益得以长期发挥,可逐步形成近自然森林经营模式。因此,为达到经济与生态双重效益高值,在福建省的森林经营中建议采用桉树∶红锥∶枫香∶火力楠=4∶2∶2∶2的模式。
This paper presents an experimental analysis of mixed-species management by combining Eucalyptus(a tree species with a short management cycle and significant economic benefits)with Castanopsis hystrix,Liquidambar formosana Hance,and Michelia macclurei Dandy(species offering long-term ecological benefits).The study aims to address the drawbacks of pure Eucalyptus plantation management,explore multi-species forest management models that achieve multiple benefits,and provide references for sustainable forest management and the sustainable development of forest management units.The trial utilized three planting models with the following species ratios:Eucalyptus:Castanopsis hystrix:Liquidambar formosana:Michelia macclurei=6∶2∶1∶1;Eucalyptus:Castanopsis hystrix:Liquidambar formosana:Michelia macclurei=4∶2∶2∶2;Eucalyptus:Castanopsis hystrix:Liquidambar formosana:Michelia macclurei=2∶3∶3∶2.After 9 years of growth,the experimental forest showed that the management model with a Eucalyptus:Castanopsis hystrix:Liquidambar formosana:Michelia macclurei=4∶2∶2∶2 resulted in the highest forest stock volume.Due to the higher proportion of Castanopsis hystrix,Liquidambar formosana,and Michelia macclurei,the forest's long-term ecological benefits were realized,gradually forming a close-to-nature forest management model.Therefore,to maximize both economic and ecological benefits,a planting model with a species ratio of Eucalyptus:Castanopsis hystrix:Liquidambar formosana:Michelia macclurei=4∶2∶2∶2 is recommended for forest management in Fujian Province.
