摘要
采用植物群落学和植物种群学的研究方法 ,从数量和质量特征两个方面研究了海南岛坝王岭热带天然林的植物物种多样性。结果表明 :(1 )该地区不同植物群落的优势种类组成差别较大 ,彼此之间的物种相似性水平低 ;(2 )相对于低地雨林而言 ,该地区的山地雨林物种数量较多 ,物种均匀度较高 ,主要优势种的优势程度较弱 ;(3)在优先考虑物种稀有性的前提下 ,根据各植物物种在群落中所处的位置及其分布情况 ,可将该地区的植物物种分为珍稀濒危种、特征种和普遍种等三种主要类型。最后 ,对如何保护该地区的植物物种多样性进行了初步探讨并提出建议。
Using phytocoenological and phytodemographic methods, we studied the quantitative and qualitative characteristics of plant species diversity of tropical natural forest in Bawangling, Hainan Island. The results showed that 1) plant communities of this area had great differences in the composition of dominant species and there were low species similarities among the communities; 2) the mountain rain forest in this area had a larger number of species, a higher level of species evenness and relatively weaker dominance of the species than the lowland rain forest; 3) setting priority according to species rarity, all the plants in this area can be divided into three categories according to their positions and distributions in the communities, namely rare and endangered species, characteristic species, and common species, and 4) some suggestions were put forward for the conservation of plant species diversity in this area.
