摘要: 对海南岛不同海拔高度青皮为优势种的群落进行了典型抽样调查,共计调查临时样方13个,总面积2 800m2,分析了不同海拔高度对青皮林群落的物种组成、结构及群落特征的影响。分析结果表明:不同海拔高度青皮群落的优势种组成存在显著差异;青皮成树(DBH≥5cm)重要值和群落多样性与海拔高度呈相反变化趋势;不同海拔高度青皮成树株数各径级分布均呈倒J曲线分布,但差异较大,随海拔高度的升高,倒J曲线越趋于平缓;成树青皮株数、比例和断面积均随海拔高度的升高而减少,青皮平均胸径则随海拔高度的升高而增加。

Abstract: A total of 13 temporary sample plots with a total area of 2800 m2 were surveyed with typical sampling method to investigate Vatica mangachapoi dominant communities at different altitudes in Hainan Island.The effects of different altitudes on species composition,structure,and community characteristics of Vatica mangachapoi dominant communities were analyzed.The analysis results showed:there were significant differences on dominant species composition of Vatica mangachapoi communities at different altitudes; the changes of Vatica mangachapoi important value and community diversity for trees (DBH≥5cm)showed opposite trends as the altitude increases; tree number distributions of Vatica mangachapoi (DBH≥5cm)at different altitudes all showed inverted J-curve distribution among diameter classes,but the difference among them was significant and inverted J-curves tend to be much more flatr as the altitude increases; Vatica mangachapoi tree numbers,ratio and basal area (DBH≥5cm)decreases as the altitude increases,but average diameter of Vatica mangachapoi at breast height increases as the altitude increases.

Key words: community structure, diversity, Vatica mangachapoi, Hainan Island
