摘要:

利用地面观测和单绳上树法初次对布龙自然保护区勐宋片区开展的附生维管植物调查表明:1) 在6个样地77株宿主上 (共调查96株乔木,占地约02ha),共有1756株、丛个体,隶属14科47属103种;相比世界其他区域,物种丰富度处于旧世界热带水平区间,高于温带,但明显低于新世界热带水平;2) 兰科植物为最丰富的类群 (60%),其次为蕨类植物 (24%),其他类群占16%; 3) 垂直分布特征研究表明,距地面10~15m的中等高度带为物种最丰富的区间,约有51%的物种;0~5m高度带为个体数量最多的区间,共有约24%个体,揭示了除中等高度带以外的另一个重要附生生境;4) 常见的绞杀型榕属植物未见,而半附生植物密脉鹅掌柴 (Schefflera elliptica) 和多蕊木 (Tupidanthus calyptratus) 数量较多。

Abstract:

The first survey of vascular epiphytes was conducted using ground based inventory assisted by single rope technique in the recentlyestablished Bulong Nature Reserve, Xishuangbanna, China. Results indicated that vascular epiphytes were abundant and diverse there. On a total of 77 phorophytes in six plots (96 trees were examined in total, covered ca. 02ha area), 1756 individuals were recorded and were identified to 103 species (47 genera, 14 families). Compared with other regions, the epiphytes were as diverse as Paleotropics, and more diverse than temperate zone, but significantly less than the Neotropics. Orchids and ferns comprised 60%, 24% of the total flora, respectively, while others only took up 16%. The highest species richness and richest lifeform diversity was found in the middle canopy zone from 10 to 15m (51% of total species), where also supported high individual abundance (19% of total individuals). Besides the middle canopy, the most abundant zone of epiphyte individuals was detected at the base of the trunk (zone 0-5m, 24% of total individuals and 37% of total species), indicating another important niche for epiphytes in this forest environment. Primary hemiepiphytic figs were rare in the area and were not found on the surveyed host trees, while hemiepiphytic Araliaceae species (Schefflera elliptica and Tupidanthus calyptratus) were popular.
