摘要
楠木类植物包括樟科(Lauraceae)的润楠属(Machilus)和楠属(Phoebe)植物及一些近缘种。自然分布的楠木群落正在逐步减少,为保护和合理利用楠木资源,本研究采取实地调研的方法,对长阳县境内3个乡镇(高家堰、贺家坪和龙舟坪)的楠木群落进行初步调查,并记录其生境条件、群落特征,分析该地楠木(楠属和润楠属)植物群落的群落结构特征、各生境因子对其分布的影响。野外调查发现5种没有记载过的楠木植物:湘楠(P.hunanensis)、白楠(P.neurantha)、华润楠(M.chinensis)、小果润楠(M.microcarpa)以及润楠(M.nanmu),初步确认是在长阳县内的首次记录。同时,调查发现该地阴坡、海拔640~698m以及坡地上部更适宜楠木植物生长。
Phoebes are a group of excellent and valuble timeber trees in China,it consists of the species of Machilus and Phoebe. The natural population and community of phoebes are gradually decreasing. For the protection and rational utilization of Phoebe community,in the present study,based on field data,we investigated the population and community of Machilus and Phoebe in Changyang County, Hubei Provience,and recorded the habitat and community characteristics. Six of phoebes, such as P. hunanensis, P. neurantha, M. chinensis,M, microcarpa,and M. nanmu were found in the county for the first time. Meanwhile,it was found that the shady slope and the altitude of 640-698 m on the upper mountain were more suitable for the growth of phoebes.
