曼稿自然保护区野生大花万代兰分布现状

A Study on Distribution of Wild Vanda coerulea in Mangao Nature Reserve

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．

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 acutissirna, Dalbergia fusca and Castanopsis argyrophylla. According to the value for the protection and the threats on wild Fanda coerulea, the paper proposes the measures including strengthening management and protection, long-term monitoring for the distribution and population quantity, conducting study on techniques for artificial culture and so on.
