鹿角蕨的资源调查与保护

Resources Investigation and Conservation of Platycerium wallichii

依托云南省第二次野生植物资源调查项目,对鹿角蕨在德宏州分布设置8个点进行实测法调查,并从鹿角蕨的生物学特性、生态学特性、群落特征等方面进行分析研究。结果表明:在8个点中,其中有5个分布点为本次调查到的新分布点;鹿角蕨在保护区内主要附生在曲枝榕、八宝树、西南猫尾木和印度血桐等植物上,在保护区外主要附生在黄葛树、露兜树、橡胶树等乔木上,与这些植物伴生的主要有桑科、大戟科、菊科、禾本科等植物,群落组成复杂,植物种类丰富;空气湿度和郁闭度是构成鹿角蕨生境的决定性因素。

According to the Second Wild Plant Resources Survey Project in Yunnan,a survey was conducted on8 natural sample zone of Platycerium wallichii in Dehong.We analyzed the community characteristics,species composition and resource conservation value of Platycerium wallichii.We found five new distribution in eight distributions.Platycerium wallichii mainly epiphytes on Ficus geniculata,Duabangagrandiflora,Dolichandrone stipulata,Macaranga indica and other plants in protected areas.Outside the reserve,the main epiphytes were Ficus virens var.sublanceolata,Macaranga indica,Pandanus tectorius,Hevea brasiliensis and so on.The main plants associated with these trees were Moraceae,Euphorbiaceae,Compositae,Gramineae,which reflect the complex community and rich plant species.Air humidity and canopy density were the decisive factors in the habitat of Platycerium wallichii.
