茂兰自然保护区掌叶木资源调查及种子萌发实验

Investigation of Palm Leaf Wood Resources and Seed Germination in Maolan Nature Reserve

为了更好地了解和掌握掌叶木在茂兰保护区的分布情况及生长状态,笔者采用样带法对茂兰保护区的掌叶木资源的分布、植物学特性、生境特征和资源特点进行调查统计、分析,并开展萌发栽培试验,观察掌叶木生物学性状变化,旨在掌握茂兰保护区掌叶木植物种质资源的分布、保护现状,探讨掌叶木濒危原因和保护对策,制定科学合理保护对策,为开展后续的研究工作打下基础。结果表明:掌叶木在茂兰保护区内呈随机集群和星状分布于4个管辖区域,多生长在石面、石沟、石缝这些严酷生境中,能正常开花结果,天然更新能力差,幼苗幼树缺乏,成年植株长势一般,种群呈衰退趋势。

In order to better understand and master the distribution and growth status of palm leaf wood in Maolan reserve, the author used sample band method to investigate and analyze the distribution, botanical characteristics, habitat characteristics and resource characteristics of palm leaf wood in Maolan reserve, and carried out germination and cultivation experiments to observe the changes of biological characters of palm leaf wood. The results showed that the palm leaves were randomly clustered and stellate distributed in four areas of Maolan Reserve. They grew in the harsh habitats of stone face, stone ditch and stone seam.
