| 摘 要： | 在总结相关文献的基础上,通过对分布于广东西南地区的兰花蕉和广西十万大山的长萼兰花蕉种群的样地调查,分析兰花蕉分布规律、种群结构、濒危现状及其濒危原因,并提出相应的保护措施。兰花蕉空间分布格局呈聚集型,种群规模小,致濒的原因是环境破坏和自身繁殖能力下降。从形态学特征上分析兰花蕉及长萼兰花蕉的5个叶部特征,结果表明不管在种水平还是在居群水平,兰花蕉及长萼兰花蕉5个形态特征差异都达显著(P<0.05),其变异相对不太稳定,已出现一定的分化,且呈连续性。

| Abstract: | On the basis of summing the relative literatures and investigating on O.chinensis var.chinensis T.L.Wu in the southwestern of Guangdong Province and O.chinensis var.longisepala in Shiwandashan mountain in Guangxi Zhuang,the distribution law,the population structure,the endangered status and reason of O.chinensis were analyzed and the corresponding protection measures were provided.The space distribution of O.chinensis was in cluster aggregation with small population.The endangered reason of O.chinensis was the environmental damage and the decline of their own reproductive capacity.Five leaf morphological characters of O.chinensis var.chinensis and O.chinensis var.longisepala were analyzed.The results indicated that 5 leaf morphological characters of O.chinensis var.chinensis and O.chinensis var.longisepala were in significantly difference(P<0.05) no matter at species or at population level.The variances of their leaves were relatively unstable and some continuous differentiation had been appeared. |
