摘　　要：通过分析毛竹林下红豆树、浙江楠、浙江樟生长及生理特性的密度效应,探索适合毛竹纯林转变为竹阔混交林的模式体系。结果表明:毛竹林下红豆树、浙江楠、浙江樟的生长具有较为明显的差异,红豆树和浙江樟的长势明显好于浙江楠。3个树种的光合速率(P_(n))、气孔导度(G_(s))、保护酶活性、可溶性糖质量分数、可溶性蛋白质量分数均存在显著差异,说明浙江楠、浙江樟在毛竹林下生长存在一定的胁迫,而红豆树的类胡萝卜素质量浓度及POD活性较高,增加了细胞保护能力。3个树种中,红豆树更适合在毛竹林下生长。By analyzing the density effect of growth and physiological characteristics of Ormosia hosiei Hemsl,Phoebe chekiangensis and Cinnamomum chekiangense under Phyllostachys edulis forest,we explored the model system suitable for transforming Phyllostachys edulis pure forest into Phyllostachys edulis-broadleaf mixed forest.The results showed that the growth of O.hosiei,Phoebe chekiangensis and C.chekiangense under Phyllostachys edulis forest had obvious differences,and the growth of O.hosiei and C.chekiangense was significantly better than that of Phoebe chekiangensis.There were significant differences in the photosynthetic rate(P_(n))and stomatal conductance(G_(s)),protective enzyme activity,soluble sugar and soluble protein mass fraction,indicating that there was a certain stress in the growth of Phoebe chekiangensis and C.chekiangense,while the high carotenoid quality concentration and POD activity of O.hosiei increased the ability of cell protection.Among the three tree species,O.hosiei is the most suitable to grow under Phyllostachys edulis forest.
