摘　　要：[目的]研究不同坡位对黄菠萝容器苗造林幼树生长的影响,以期为适地适树发展黄菠萝人工林提供理论支持。[方法]对黄菠萝幼树在不同坡位的生长状况进行综合调查分析,包括高生长、径生长、根系生长和生物量等指标。[结果]高生长方面,坡下的黄菠萝幼树最好,坡上的次之,坡中的较弱;地径、当年枝基径、根系总长度和根系表面积方面,坡上的最大,坡中、坡下的较小;根体积为坡中的较大,坡上次之,坡下的最小;根平均直径坡下的最大,坡上和坡中基本相同;根重在生物量分配率上占了将近50%,坡下根系生长较弱,生物量最低。[结论]采用黄菠萝容器苗造林,可以抵消不同坡位立地条件所引起的幼树高生长差异。[ Objective ] The aim was to study the effects of different slope positions on the growth of Phellodendron amurense container seed- lings, in order to provide theoretical supports on the development of P. amurense plantations. [ Method ] The growth status of P. murense on different slope positions was analyzed, including high growth, diameter growth, root growth and biomass. [ Result] On the high growth, the young trees on the bottom slope was the best, then were the top and the middle slopes; on the ground diameter, current year branch diameter, total root length and root surface area, the young trees on the top slope was the best, then were the middle and the bottom slopes; on the root volume, the young trees on the middle slope was the best, then were the top and the bottom slopes; on the root diameter, the young trees on the bottom slope was the best, the top and the middle slopes were basically the same; root on biomass allocation rate accounted for nearly 50% ,the root growth was weak on the bottom slope, the biomass was the lowest. [ Conclusion] P. amurense container seedling could offset growth differences caused by different position of slope site conditions of the young trees.
