摘要
棕榈藤是一种重要的非木质森林资源,在全球生物多样性保护和经济发展方面起着重要的作用。为了解热带雨林恢复过程及林分结构对棕榈藤分布生长的影响,应用样方调查和排序分析法,对海南岛甘什岭3种不同恢复阶段的次生雨林进行调查。结果表明:(1)棕榈藤多度在恢复中前期最高(74±43),中期次之(32±37),前期最低(0±0),棕榈藤频度分布整体表现为中前期>中期>前期。中期的杖藤(13.62±8.39 mm)、小钩叶藤(8.01±3.05 mm)、多果省藤(6.54±7.52 mm)和黄藤(3.62±2.52 mm)地径生长大于中前期(7.52±3.75,6.72±3.33,4.73±5.20,3.51±2.4 mm),白藤(1.32±0.53 mm)小于中前期(7.87±6.45mm);中期林分的杖藤(131. 35±62. 72 cm)和黄藤(23. 93±15. 23 cm)高生长大于中前期(90.02±92.13,23.72±17.93 cm),但白藤(8.31±0.85 cm)、多果省藤(32.43±30.91 cm)和小钩叶藤(31.62±8.74 cm)小于中前期(54.30±50.77,48.46±78.11,34.35±7.10 cm)。(2)棕榈藤多分布在恢复中前期和中期林分中,灌丛群落不利于棕榈藤分布,黄藤、杖藤、多果省藤和白藤倾向于分布在恢复中前期的群落中,小钩叶藤多分布在恢复中期的群落中。(3)平均树高与棕榈藤多度均呈正相关,立木密度与棕榈藤多度呈正相关,最大胸径、平均胸径与小钩叶藤多度呈正相关。建议资源保护要加强对热带雨林的保护,资源培育利用要根据不同藤种进行林分结构调整或者选择适宜林分结构进行近自然培育。
Rattan is an important non-woody forest resource and plays a critical role in global biodiversity conservation and economic development. To understand the effects of forest restoration process and stand structure of tropical rainforest on the distribution and growth of rattan,we conducted a research on secondary rain forests in three different restoration stages in Ganshiling,Hainan Island using the methods of quadrat investigation and sequencing analysis. The results showed that:( 1) The abundance of rattan was the highest in the early-middle stage of restoration( 74±43),followed by the middle stage( 32±37),and the lowest in the early stage( 0±0). The frequency distribution of rattan manifested overall as early-middle stage>middle stage>early stage.The ground diameter growth of Calamus rhabdocladus( 13. 62 ± 8. 39 mm),Plectocomia microstachys( 8.01±3.05 mm),C. walkerii( 6.54±7.52 mm) and Daemonorops jenkinsiana( 3.62±2.52 mm) in the middle stage was greater than that in the early-middle stage( 7.52±3.75,6.72±3.33,4.73±5.20,3.51±2.4 mm). The ground diameter growth of C. tetradactylus( 1.32 ±0.53 mm) was smaller than that in the middle stage( 7.87±6.45 mm). The height growth of C. rhabdocladus( 131.35± 62. 72 cm) and D. jenkinsiana( 23. 93 ± 15. 23 cm) in the middle stage was greater than that in the early-middle stage( 90. 02 ± 92. 13,23. 72 ± 17. 93 cm),but the height growth of C. tetradactylus( 8.31±0.85 cm),C. walkerii( 32.43±30.91 cm) and P. microstachys( 31.62±8.74 cm) was lower than those in the early-middle stage( 54.30±50.77,48.46±78.11,34.35±7.10 cm).( 2) Most of the rattan species were distributed in the forests at the early-middle stage and middle stage of the restoration. The shrub communities were not conducive to the distribution of rattan. D. jenkinsiana,C. rhabdocladus,C. walkerii and C. tetradactylus tended to be distributed in the communities at the early-middle stage of the restoration,while P. microstachys was mostly distributed in the communities at the middle stage of the restoration.( 3)The average tree height was positively correlated with the abundance of rattan. Stem density was positively correlated with the abundance of rattan. The maximum and average diameters at breast height were positively correlated with the abundance of P. microstachys. It was suggested that the protection of tropical rain forests should be strengthened in respect of the conservation of rattan resources and that stand structure should be adjusted according to different rattan species or suitable stand structure should be selected for near-natural cultivation.
