竹阔混交林研究进展与展望

Progress and Prospects of the Research on Mixed Bamboo and Broadleaf Forest

对我国竹阔混交林经营模式的相关研究作了综合概述,阐述了混交林空间分布格局的研究方法,毛竹对阔叶树的扩张方式和竞争机制。竹阔混交林可更好地权衡经济效益、生态效益、社会效益。在毛竹林不同地域环境,搭配适宜的伴生树种,可以改善土壤自肥能力,提高空间利用率,增加毛竹生产力。混交比以7∶3和8∶2,混交分布以团状和星散均匀分布为好。

This paper introduced the growth status of moso bamboo forest in our country,and the research was made with a comprehensive overview,which is used to promote the recent accepted business model of mixed bamboo and broadleaved forest. The research methods of the spatial structure and pattern,the com-petitive mechanism,the expansion method of moso bamboo was reviewed for mixed forests. Research shows that mixed bamboo and broadleaved forest can better weigh economic,ecological and social bene-fits.Moso bamboo forest can improve the soil exploit ability,improve space utilization and increase the bamboo productivity by collocating appropriate associated tree species in different geographical environ-ment. The mixed ratio 7 ∶3 or 8 ∶2 is extensively applied,and the uniform distribution of clumps and scatter of mixed forest is better.
