摘要
本部分对五指山森林植被的植物种群与森林结构进行定量和定性的分析研究，结果表明：森林群落具备热带森林群落特征，群落区系组成成分以热带亚洲成分为主；群落结构复杂，层次多样化；物种丰富，物种多样性指标大；群落中的种群分布格局、种间关系和频度分布规律等都说明物种独立分布性高，这样有利于充分利用丰富的热带资源；森林植被的动态特点是，森林群落中的树高（立木级）与个体数的关系为“倒丁”型模式，表现出热带森林具有强大的后备军来维持顶极状态系统的动态平衡．
The forest vegetation of Wu-zhi Shan Mt. is provided with characters of tropicalforest vegetation: more complicated compositions of plant communities, especially asiatropiccompositions of 30. 9% , more complicated structures of plant communities; minimal-area 3 500￣4 000m￣2 in the tropical lawland rain forest and 2 300￣2 500m￣2 in the tropical montane rainforest; higher species diversity and evennees (D=5.38 and 5. 34,J= 77. 8 and 82. 6) that alarge higber than south sub- tropical broad-leaf evengreen forest; better relationship betweenforest and environment that is showed by species associations. pattens and frequence lower.“Down J” model of relationship between stand classes and numbers of species is a characterof forest vegetation dynamics. “Down J”model shows that tropical forest have enough newrecruitments maintaining the dynamics equilibrium of the climax system.
