摘要:

研究海南霸王岭热带山地雨林原始林与伐后林的物种多样性及木质藤本与支持木的关系。结果表明:原始林中树木的物种丰富度和多度低于伐后林( P <0.05),而木质藤本的物种丰富度和多度在原始林与伐后林间无显著差异; 原始林中树木的平均附藤率和平均每木附藤数均高于伐后林( P <0.05),而平均每藤攀附支持木个体数表现为伐后林高于原始林( P <0.05); 在原始林中树木胸径与平均每木藤本数间呈显著的三次函数关系,伐后林中树木胸径与平均每木藤本数间呈显著的幂函数关系; 树木高度与平均每木藤本数在2林型中均呈显著的三次函数关系。

Abstract:

Species diversity of trees with DBH ≥1 cm and their hosted lianas were inventoried, and the liana-tree relationship was analyzed as well, in the primary evergreen forest and the post-logged forest in tropical mountains of the Bawangling Nature Reserve of Hainan Island. The results showed that the richness and abundance of trees were significantly higher ( P < 0.05) in the post-logged forest than the primary forest, but the richness and abundance of lianas were not significantly different in the two forest types. The average proportion of tree attached with lianas and the number of lianas per tree were significantly higher in the primary forest than in the post-logged forest( P < 0.05), but the number of host trees per liana was relatively lower in the primary forest( P < 0.05). In the primary forest, there was a cubic function relationship between the DBH of host trees and the mean number of lianas per tree. In the post-logged forest, there was a power function relationship between the DBH of host trees and the mean number of lianas per tree. The relationship between the height of host trees and the mean number of lianas per tree was cubic in the two forest types.

Key words: lianas, host tree, primary forest, post-logged forest, montane rain forest, Bawangling
