| 摘 要： | 在西双版纳曼稿自然保护区的4个天然植被亚型中选设了5条调查样线，以搞清自然保护区大花万代兰的垂直分布、生境选择及其附主植物．结果表明：曼稿自然保护区海拔1130～1600m范围均有野生大花万代兰分布，分布最为集中的是海拔1200～1450m的针阔混交林；多分布于林木上层郁闭度50％～60％的阳坡地段；主要附主植物有毛叶青冈、大叶栎、黑黄檀、银叶栲等．针对野生大花万代兰具有的保护价值及其目前所面临的各种威胁．提出加大管护力度、对其分布及种群数量进行长期性监测、开展人工培育技术研究等保护建议．

| Abstract: | Five-sample-route survey were selectively designed from 4 sub-types of natural vegetation in Mangao Nature Reserve to make clear vertical distribution,site selection and epiphyte Vanda coerulea.The result showed that wild Vanda coerulea mainly centralized in conifer-broadleaf mixed forest at the elevation of 1130 to 1600m and on the southern slope of mountain with enclosure of 50%-60%.The most preferred host trees are cyclobalanopsis kerrii,Quercus griffithii,Quercus acutissima,Dalbergia fusca and Castanops... |
