摘　　要：毛竹是一种重要的经济用材竹种,为分析上阔下竹经营对毛竹林生产力的影响,我们调查了福建省霞浦县内不同比例的上阔下竹混交林Ⅰ(48%)、Ⅱ(32%)、Ⅲ(30%)、Ⅳ(20%)和Ⅴ(14.3%),通过分析毛竹胸径、立竹度和叶面积指数,对5座混交林进行研究。研究表明:5座山的毛竹平均胸径依次为Ⅱ(12.1 cm)>Ⅲ(10.4 cm)>Ⅰ(10.3 cm)>Ⅴ(9.5 cm)>Ⅳ(9.4 cm),且差异显著,Ⅱ山体的立竹度和叶面积指数均最高,因此,当阔叶林投影面积比例在32%时,毛竹林生产力最高。本研究可以为毛竹林生态经营、长期生产力保持提供科学依据。Moso bamboo,Phyllostachys edulis heterocycla cv. Pubescens,is a significant economic plant. To analyze the effect of broad-leaved forest on the productivity of moso bamboos,we investigated five mountains with different proportions of broad-leaved forests to moso bamboo forests [Mountain-Ⅰ( 48%),Mountain-Ⅱ( 32%),Mountain-Ⅲ( 30%),Mountain-Ⅳ( 20%),and Moutnai-Ⅴ( 14. 3%) ]in Xiapu county of Fujian Province,and the diameters at breast height( DBHs) of moso bamboos were measured. We find that the mean DBHs for five mountains are 12. 1 cm( Mountain-Ⅱ),10. 4 cm( Mountain-Ⅲ),10. 3 cm( Mountain-Ⅰ),9. 5 cm( Mountain-Ⅴ),and 9. 4 cm( Mountain-Ⅳ),respectively,which have significant difference; both the spatial densities and leaf area index( LAI) of Mountain-Ⅱare the highest. Thus,the effective productivity of moso bamoos on Mountain-Ⅱ with a 32%proportion of broad-leaved forest is the largest. In addition,we aimed to provide a new management pattern for the mixed forest of hardwoods and moso bamboos, to attain the sustainable management for developing moso bamboos.
