| 摘 要： | 通过对扁刺栲—华木荷林区针阔混交林、次生阔叶林的群落调查以及扁刺栲的树干解析．研究结果表明：(1)扁刺栲在针阔混交林与次生阔叶林中,胸径快速生长期分别在a8～12和a10～14之间,生长高峰值分别出现在a10和a12,最大值分别为1．07cm和0．85cm．(2)扁刺栲在针阔混交林与次生阔叶林中,树高快速生长期分别在a6～10和a10～14之间,生长高峰值分别出现在a8和a10,最大值分别为0．55m和0．56m．(3)在针阔混交林中,16a生扁刺栲单株材积达0．0134m^3,而在次生阔叶林中只有0．0103m^3．在分析不同林分中扁刺栲生长差异及其原因的基础上,建议对次生阔叶林经营应采用动态管理．

| Abstract: | The community investigation and stem analysis were conducted in order to study the stem growing process of 16-year-old Castanopsis platyacantha in the conifer and broad-leaved mixed, forest and secondary broad-leaved forests. The results indicated that:(1) in the conifer and broad-leaved mixed forest and secondary broad-leaved forests, the time with high peak of annual growth increment of breast height diameter(DBH) and tree height were the 10th and 12th, 8th and 10th year respectively, and maximal value of annual growth increment of breast height diameter and tree height were 1.07 cm and 0.85 cm, 0.55 m and 0.56 m, respectively; (2)the individual tree volume of 16-year-old Castanopsis platyacantha was 0.013 4 m 3 and 0.010 3 m 3 in the conifer and broad-leaved mixed forest and secondary broad-leaved forests, respectively. Finally, based on the analysis of different growth processes of Castanopsis platyacantha and its reasons in the different stands, the dynamic management of secondary broad-leaved forest was proposed.
