| 摘 要： | 桫椤是已经发现的唯一木本蕨类植物,桫椤的化石证据表明它是与恐龙同期生长的植物,是木本植物的活化石之一。自贡世界地质公园荣县金花桫椤自然保护区,现存有1.6万多株野生桫椤,是公园的活化石,成片的桫椤生长于山谷中,成带状分布,植株生长茂盛。虽然保护区内桫椤数量较多,但分布较为狭窄,幼苗数量少且分散,自然更新和发育受到一定制约。对此建议增加人工干预,进行相关的人工栽培和保育工作。

| Abstract: | Cyathea is the only woody fern that has been discovered so far. Fossil evidence indicates that it was grown contemporaneously with dinosaurs and is one of the living fossils of woody plants. There are more than 16, 000 Cyathea in the Jinhua Cyathea National Nature Reserve, Rongxian of the Zigong World Geopark. They grow in the dark, dank valleys. However, most of the seedlings in the valley belong to other tree species;Cyathea is a small and scattered seedling with narrow distribution and poor natural renewal. Therefore, it is suggested to increase artificial intervention and carry out related artificial cultivation and conservation work. |
