| 摘 要： | 尖峰岭国家级自然保护区三分区的青皮林是目前海南岛保存最好的林分之一，其生态系统的原生性较强．组成种类繁多，林分结构合理，平均胸径为28．6cm，最大植株胸径达143．3cm，23个样方中有14个样方出现了胸径≥70cm的大乔木；林木蓄积量高达469．773m^3／hm^2，而青皮、细子龙、野生荔枝、盘壳栎等13个种的蓄积量占总蓄积量的45％，其余301个少见种或偶见种的蓄积量只占55％，反映了青皮是热带常绿季雨林生态系统关键种的现实。青皮与细子龙、野生荔枝等的最佳分布海拔在300m～650m之间，它们与向低海拔分布的白茶、翻白叶和向高海拔分布的大叶白颜、青兰、拟核果茶等一道组成了热带常绿季雨林的表征种类。

| Abstract: | The Vatica mangachapoi forest in Jianfengling of Hainan Island, China, is one of the best protected forests in Hainan.The species component in Vatica forest is most complex comparing with subtropical or temperate forest, and the forest structure is in reason. The average DBH of the forest is 28. 6cm and the maxim DBH is up to 143. 3cm, and the timber volume is up to 469.773m3/hm2 .The timber volume of 13 dominant species including Vatica mangachapoi occupied about 45% of the total. The best distribution range in altitude of Vatica mangachapoi, Amesiodendron chinensis, Litchi chinensis var. euspontanea is about from 300m to 600m,and these species are the key stone species in tis forest ecosystem. |
