竹叶兰(Arundina graminifolia)具有重要的药用、景观价值,对分布在深圳梧桐山国家级风景名胜区的典型群落进行调查,样方物种数共41种,隶属于19科37属。重要值排名前5的分别为竹叶兰(49.77)、猪笼草(25.84)、金丝草(25.78)、芒萁(17.34)和石菖蒲(14.85)。Shannon-Wiener Index(h)为1.22。竹叶兰的野外分布范围较狭窄,并呈片段化,不同群落中时常有其他兰科植物共存。建议对该类岩壁特色植物群落整体保护,形成独特的“画壁”景观。
Arundina graminifolia has important medicinal and landscape values. The typical communities distributed in the Wutongshan National Scenic Area in Shenzhen were investigated. There were 41 species belonging to 37 genera and 19 families. Important value of the top 5 were respectively bamboo (49.77), Nepenthes (25.84), gold grass (25.78), Mansfield (17.34) and Shichangpu (14.85). The Shannon-Wiener Index (h) is 1.22. The distribution of the wild bamboo leaves narrow, and was fragmented, often in different communities coexistence of other orchidaceae. It is suggested that the overall protection of this type of rocky plant community should be protected to form a unique landscape painting.
