| 摘 要： | 对峨眉山峨眉拟单性木兰群落特征与种群结构的初步研究表明:1、蛾眉拟单性木兰及其群落分布局限,地形、土壤、气候条件较为特殊;2、该群落与中国云南和东部亚热带常绿阔叶林具有广泛的联系,并具各“顶极群落”的特征;3、峨眉拟单性木兰林的两个基木群丛为:(A)蛾眉拟单性木兰+四川人头茶+包石栎-箭竹-苔草群丛与 (B)黄心夜合+大叶新木姜子+峨眉拟单性木兰-箭竹-单芽狗脊群丛;4、人类和猴群的活动与干扰直接威胁着该种种群和群落的生存与稳定。

| Abstract: | This paper deals with the distribution, characters and population structure of the Parakmeria omeiensis community on Emeishan in West China. The results show: 1. Parakmeria omeiensis and its community distribute in a limited area with a special environment of topography, soil and climate. 2. The community has a widely relation to subtropical evergreen broad-leaved communities in Yunnan and East China and a characteristics of "climax" 3. The two associations of the Parakmeria omeiensis forest are: (A) Parakmeria omeiensis + Gordonia szechuanensis + Lithocar pus cleistocarpus - Sinarundinaria nitida - Carex sp. association and (B) Michelia martinii + Neolitsea tevinei + Parakmeria omeiensis-Sinarundinaria nitida + Woodwardia japonica association. 4. The activity and disturbance of mankind and monkeys directly threaten the existence and stability of the population and its community. |
