海南霸王岭壳斗科植物优势的山地雨林群落特征初步研究

Study on the Community Characteristics of Fagaceae Dominance in Tropical Montane Rain Forest in Bawangling of Hainan Island

通过对霸王岭地区壳斗科植物优势的山地雨林群落的调查分析,得出以下结论:在样地中共有维管束植物249种,分属于84科,166属,其中蕨类植物12科18属25种,裸子植物3科4属5种,被子植物69科144属219种,表现了该群落的物种丰富程度;在种子植物的地理区系分布方面,该类型群落的种子植物的科和属的地理区系分布类型都有10种,总体而言都是以热带区域的分布类型为主,具有强烈的热带性特征;根据Raunkiaer的生活型划分原则,群落中的植物以高位芽的生活型为主,尤其是中高位芽生活型种类最多;群落中植物的叶的特征是以革质、全缘、单叶、中型叶为主,体现了该地区群落的气候和水热条件相适应的特征。

According to the investigation and analysis of the tropical montane rain forest of Fagaceae dominance in Bawangling of Hainan Island,there were 84 families,166 genera,249 species of vascular plants,among which there are 12 families,18 genera,25 species of pteridophyta,3 families,4 generas,5 species of gymnosperm,69 families,114 genera,219 species of angiosperm.The floral composition of the families and genera in the community can be divided into 10 areal types,and the tropical type is dominant and reflects that the fields show strong tropical characteristics.According to Raunkiaer’s rule,phanerophytes are dominant among the life form,especially the mesophanerophytes.The leaves are mainly leathery,entire,simple and mesophyll,which coincides with the temperature and moisture conditions in Bawangling.
