摘要：【目的】分析海南霸王岭热带山地雨林6 hm^(2)森林动态监测样地物种组成与群落特征,为深入理解热带天然林生物多样性维持机制提供基础依据。【方法】基于森林动态监测样地的群落调查数据,对样地内胸径(DBH)≥1 cm的所有木本植物进行了调查和统计,从物种组成特征、数量特征、科属地理成分、主要优势树种的径级结构和空间分布格局等方面入手,分析群落物种组成和特征。【结果】1)样地中物种丰富,组成复杂多样。6 hm^(2)样地内DBH≥1 cm的植物共有407种40783株个体,分属79科215属;平均植株密度为0.68株/m^(2),平均物种数为67.83种/hm^(2)。2)植物区系具有典型的热带植物区系特点。热带分布的科、属分别占样地总科、属的68.35%和88.83%。3)群落更新良好。样地内所有物种全部个体的径级分布呈典型的倒“J”型。4)优势树种的种群空间分布格局以聚集分布为主,不同物种表现为不同的空间格局类型且具有明显的空间尺度依赖性。【结论】本研究提供了海南霸王岭热带山地雨林6 hm^(2)森林动态监测样地内的物种组成和群落结构等基本信息,可为热带天然林物种共存机制、生物多样性与生态系统功能关系等方面的研究提供基础依据,也可为海南旗舰物种海南长臂猿的有效保护和海南热带雨林国家公园建设等奠定研究基础。
【Objective】The species composition and community characteristics of the 6 hm^(2) forest dynamic plot(FDP)in Bawangling tropical mountain rain forest,Hainan Island were analyzed to provide basic data for further understanding of the natural tropical forest biodiversity maintenance mechanisms.【Method】Based on the community survey data of the forest dynamic plot,all free standing trees with diameter at breast height(DBH)≥1 cm were tagged,measured and identified to species.We analyzed the species composition and community characteristics from the aspects of species composition,quantitative characteristics,geographical composition of family and genus,diameter class structure and spatial distribution pattern of dominant tree species.【Result】1)The FDP contained a rich variety of species,with a complex and diverse composition.There were 407 species and 40783 individuals with DBH≥1 cm in the 6 hm^(2) FDP,belonging to 79 families and 215 genera;the average plant density was 0.68 individuals/m^(2),and the average number of species was 67.83 species/hm^(2).2)The flora has typical characteristics of tropical flora.The tropical families and genera accounted for 68.35%and 88.83%of the total families and genera,respectively.3)The community regenerated well.The diameter class distribution of all individuals of all species in the plot showed a typical inverted"J"shape.4)The spatial distribution patterns of dominant species were dominated by aggregated distribution,and different species showed different types of spatial distribution patterns with obvious spatial scale-dependent.【Conclusion】The basic information of species composition and community characteristics provided in this study will support for the further study of species coexistence mechanisms and the relationship between biodiversity and ecosystem function in tropical natural forests.It can also provide background information for the protection of Nomascus hainanu and even the construction of National Park of Hainan Tropical Rainforest.
