拟石斛(Oxystophyllum changjiangense)为海南岛特有的珍稀濒危附生兰科植物。为阐明其附生特性,笔者以分布于海南省霸王岭国家自然保护区的拟石斛为例,在系统调查其资源现状、生境特征及宿主种类的基础上,对其附生宿主的专一性、在宿主上的分布特点及附生个体数量与宿主胸径、树皮特性的相关性等进行分析。结果表明,86.6%的拟石斛个体分布在海拔800~1 000 m且主要附生在山地雨林中水源附近的高大乔木上;附生宿主18种,多见于木兰科、壳斗科、漆树科及梧桐科的植物;附生指数在0.32~0.94之间,其中白花含笑、长柄梭罗和红锥的附生指数接近于1;拟石斛全都分布在宿主的一级分支或二级分支处,二者差异性不显著;附生数量与宿主胸径呈显著性正相关(R=0.397,P<0.05),拟石斛对树皮特性选择具有偏好性。
